RIENTATION
1.1
What is CulvertMaster?
CulvertMaster is an extremely powerful, yet easy-to-use program that helps civil engineers design and analyze culvert hydraulics, from single barrel to complex multi-barrel culverts with roadway overtopping. You will be able to use CulvertMaster within minutes of installing it. Just click the appropriate button to create a new analysis, design, or worksheet. Then enter data in clearly labeled fields with full context-sensitive help, and click to calculate. It is really that easy. CulvertMaster also allows you to solve for most hydraulic variables, including culvert size, flow, and headwater, as well as plot and generate output for rating tables showing computed flow characteristics.
You have a choice of culvert barrel shapes, including circular pipes, pipe arches, boxes and more. Flow calculations handle pressure and varied flow situations such as backwater and drawdown curves. Design discharge can be calculated using either the Rational or SCS method. Rainfall information is calculated using rainfall tables, equations, or the National Weather Services’ Hydro-35 data. CulvertMaster also plots Intensity-Duration-Frequency (IDF) curves. CulvertMaster’s flexible reporting feature allows you to print the design and analysis results in report format or as a graphical plot.
1.2
How Can You Use CulvertMaster?
CulvertMaster can design or analyze culverts and compute headwater for a range of flow rates. For a typical CulvertMaster project, you may be interested in several culvert locations and can try several different designs for each location. After reviewing the designs, you perform a detailed analysis on one of the designs. In summary, you can use CulvertMaster to: x Predict peak flows
x Size culverts
x Compute and plot rating tables and curves x Design and analyze special shapes
x View output in both US Customary and SI (metric) units x Generate professional looking reports and graphs.

3. Select one of the three examples from the element list and open it using the Open
Element command button.
The notes below explain the three elements included in the example project.
Turkey Hill Road - Design
Design example - An urban section roadway embankment with 3:1 side slopes. Uses a 50-year design event and a 100-50-year check event computed using the SCS TR-55 Graphical Peak Discharge method. Five different scenarios are explored to select the best design, based upon an allowable headwater and the engineer's estimate of construction costs.
Highway 66 & Turkey Hill - Analysis
Analysis example - Existing cross-drainage system serving an urban watershed that is currently overtopping during the design return period. The engineer must propose remedial measures. It is desired to maintain traffic, so culvert(s) must be bored to get design flood below pavement subgrade (i.e. allow 18" freeboard below finished pavement elevation).
4 Chapter 1 - Orientation
Detention Outlet Structure - Quick Calc
Quick Culvert Calculator example - For a sketch plan submittal. Engineer must provide preliminary design and cost estimate. It is known that the engineer has to provide a detention facility and estimate the required hydraulic control structure. For the 25-year design storm, this site can discharge no more than 75 cfs, and the engineer has determined that sufficient detention storage at elevation 107 can be provided. The pond bottom is at elevation 100, and this is to be designed as a dry pond (i.e. no 'dead storage'). The top of the embankment is at elevation 110.
Use a 15-foot wide embankment with 3:1 front and back slopes. The culvert has a headwall at the upstream end with a trash/kid grate, and is projecting from the downstream embankment face with riprap protection to prevent scour. The engineer made a judgment that Ke should be increased from 0.5 to 0.7. The total length of the barrel is 70 feet.

Use the Copy button to export the registration information to the Windows Clipboard so that you can paste it into other Windows applications.
Requesting Permanent Network License
System administrators who are responsible for managing network license versions of Haestad Methods' software must activate their organization’s floating licenses by obtaining a permanent license file from Haestad Methods. This may be done using the Request License button on the Registration dialog. This button will only be available for users who have purchased the network-licensing feature.
Haestad Methods uses SentinelLM License Manager software from Rainbow Technologies to manage network licensing for this application. For more information concerning the administration of the Haestad Methods floating network licensing, please refer to the Sentinel Software System Administrator’s Guide online documentation installed with your network license server software.
8 Chapter 1 - Orientation To acquire a network license file, the administrator must first generate the network locking codes for the computer that will be acting as the network license server. To get you license server locking code, use the SentinelLM echoid utility. This is installed with the license server software onto the computer acting as the network license host for this application.
The echoid utility must be run from the same computer that will act as the license server host for this particular Haestad Methods application.
Write down the values for the locking codes that are posted in the echoid utility’s message box. Be certain to record these values accurately, as they will be used by Haestad Methods to generate a custom license file keyed to the specific license server’s hardware signature. Once issued, a license key-code may not be installed on another machine. You will not be able to transport the license server to another network machine without obtaining new lock codes. With echoid values in hand, start the Haestad Methods product application on any workstation located on the network served by the license manager. You can even install and run the Haestad Methods application from the same computer that will be acting as the license server host computer.
Select Help\About from the pull-down menu to open the Registration dialog. Open the
Request License Key dialog using the Request License button. Fill out the form, then either
email or fax the completed form to Haestad Methods using the Submit Request button.
Installation Guide for Network License Versions
To set up CulvertMaster for operation as a network licensed version:
1. Place the diskette labeled Disk 1 in the floppy disk drive (commonly the a: or b: drive). 2. Place the CD in your CD-ROM drive (commonly the d: or e: drive).
3. If the Autorun feature of the operating system is enabled, setup will begin automatically. Proceed to step 5.
4. If Autorun is disabled, click the Start button on the task bar, select Run from the menu, and type d:\setup (use the actual drive letter of the CD-ROM drive if it is not the d: drive). Click OK.
5. To perform the following steps, you must have full administrator privileges for the target network-based installation folders. Follow the instructions of the Setup Wizard, which will guide you through the installation of two components:
Network deployment folder – A directory installed on a network node that is
available from all client workstations on which the license product will be installed. Users of the floating licenses will invoke the network-based installation utility
setup.exe, which will install and configure the application to each client workstation.
Network License Manager and Utilities – The license manager service executable
file that will automatically monitor availability and distribute network floating licenses to client applications as they are started up across the license hosting LAN. The license manager may be installed on any shared node in the network, but is generally located on a network server machine.
6. Start the license server using the appropriate procedure for the host machine’s operating system:
Windows NT – Use the loadls utility via the Service Loader menu option to install
controlled via the Windows NT Control Panel\Services group.
Windows 98, ME, and XP – To enable automatic license server startup, use Windows Explorer to add the license server program, Lserv9x.exe, to the Windows
system StartUp folder. Manually start the license server by running the lserv9x via the License Server menu option.
7. Announce the availability of the product via email. Instruct interested users to install the product the using the Start\Run menu command and browsing to the network deployment folder installed in step 5 to run setup.exe. The license server ships with special 30-day licenses that will allow users to begin using the application immediately. 8. Obtain a permanent license file for the application. A permanent license file must be
obtained from Haestad Methods within 30 days of receipt of the product package. Request a permanent license file by following these steps:
At the host computer on which the license server will run, use the echoid utility via the Locking Codes menu option to determine the locking codes that will be used to generate license keys for your network. The license key file will be configured specifically for the license server machine installation. Write down these locking codes.
Start the Haestad Methods product application at any workstation where the product has been installed. The product can even be installed directly on the computer acting as the license server.
Select Help\About from the pull-down menu and click the Registration button. Use the Request License button at the bottom of the Registration dialog and fill out the License Key Request form with the system administrator contact and host server locking code information. Be certain to accurately record the locking codes obtained during the previous step since inaccurate information will result in the generation of unusable license files.
Click the Submit Request button. Following the instructions in the form, e-mail or fax the form to Haestad Methods. The activation request will be processed, and a license file will be generated and e-mailed to the system administrator making the request.
9. Use the lslic utility located in the AdminTools directory to modify the permanent license file managed by the network license server. After the license key file requested above is received via e-mail from Haestad Methods, save the file attachment to a computer folder on any computer resident on the network serviced by the running license server. For future convenience, safety, and ease-of-support, it is recommended that the license file be saved in the license manager tools directory, AdminTools. This utility must be run from the operating system prompt. Enter lslic –F <filename>, where <filename> is the name of the license file attachment emailed by Haestad Methods and saved to the hard-drive. This step will install the new license key into the license file, lservrc, located on the same computer and in the same directory that the license server resides.
Once these steps are completed, floating licenses will be available to concurrent users via the network. Should the number of users exceed the number of license keys available, the unlicensed client sessions will continue to run in demo mode.
Network Deployment Folder
Interested users may install the complete product via the network deployment folder using the Windows Start\Run command. Browse to the deployment directory, and run setup.exe to install the program to a client workstation.

If you are already familiar with standard Windows interfaces, you will find CulvertMaster to be intuitive and comfortable. Even if you are not accustomed to Windows standards, just a few minutes of exploring CulvertMaster should be enough to acquaint you with the flexibility and power that this program offers.
2.1
CulvertMaster Main Window
The following figure illustrates some of the important areas that make up the main CulvertMaster window.

2.2
Menus, Toolbars, and Shortcut Keys
Anyone who has ever watched someone else use a computer should realize that not all people use computers in the same way. Some prefer to primarily use the mouse, some the keyboard, and others use a mixture of both.
For this reason, Haestad Methods’ programs provide access to the most common features through several means, including:
x Pull-Down Menus x Toolbars
x Shortcut Keys
2.2.1 Pull-Down Menus
As with any Windows-based program, the menu system provides easy access to many features. Items can be accessed by clicking the desired menu text, or by pressing the Alt key to activate the menus and then pressing the key for the underlined letter of the menu item you wish to access.
For example, to open an existing file you can use the mouse to select File\Open, or you can press the Alt and F keys (Alt + F), then O on the keyboard.
Figure 2-2: Typical pull-down menu
2.2.2 Toolbars
The toolbar buttons offer one-click access to some of the most commonly used features, giving you even quicker passage to the most frequent actions.
For example, to open an existing file (the equivalent of selecting File\Open from the pull-down menu), simply click the File Open button .
2.2.3 Shortcut Keys
Shortcut keys are the keyboard equivalent of toolbars. Key combinations, which are usually a simultaneous application of the Ctrl (Control) key and a letter key, can provide instant access to common features. If a shortcut is available for a menu item, it will be indicated in the menu itself.
For example, to open an existing file (the equivalent of selecting File\Open from the pull-down menu) you can press the Ctrl and O keys (Ctrl + O) at the same time.
2.3

3.2.2 Unit System
Although individual units can be controlled throughout the program, you may find it useful to change your entire unit system at once, to either the System International (SI) unit system or the US Customary (English) system.
When you switch to a different unit system, you will be asked to confirm this action. If you choose YES, all data will be displayed in the default unit for the selected system.
3.2.3 Enter Key Behavior
Enter Key Behavior controls which standard the Enter key follows during editing:
x CUA Enter Key – With this setting, the Enter key acts as it normally does for Windows applications. It is conforming to Common User Access (CUA) standards. This means that when you press the Enter key, it is as though you pressed the default button on the dialog. CUA Enter Key is the recommended setting.
x Tabbing Enter Key - With this setting, the Enter key behaves the same as the Tab key for editable fields (not buttons). This means that when you press the Enter key, the cursor will move to the next field in the dialog.
3.3
Calculation Options
The Calculation Options dialog enables you to set the HGL Convergence Test, Discharge Convergence Test, and Number of Profiles options, all of which adjust the speed and precision of your system design calculations.
3.3.1 HGL Convergence Test
In iterative flow balance calculations, the HGL Convergence Test value is taken as the maximum absolute hydraulic grade difference between two or more culvert system hydraulic components at final convergence. This value is also used in the standard step gradually varied flow profiling algorithm. If two successive depth iterations are within this absolute test value, the step is solved.
3.3.2 Discharge Convergence Test
In iterative flow balance calculations, the Discharge Convergence Test value is taken as the maximum relative difference between the system discharge and the sum of the flow components in the culvert system.
3.3.3 Number of Profile Steps
This option sets the number of steps used to accomplish the gradually varied flow profile within each barrel. The default setting is 5, and it is recommended that you use at least 5 steps for accuracy. Increasing the number of steps will increase the accuracy of the profile calculation.
3.4
Graph Options
These features allow you to customize the way a graph looks, and will be accessible from Rating Curve Plots. The dialog is divided into several tabs:
Titles
x Titles - There are three sets of titles for a graph: Graph title, X-Axis title and Y-Axis title. Each title set contains two levels: title & subtitle. A pie chart simply has a title and a subtitle.
x Title Font - This feature allows you to select and change the text font type for specific items on the graph or pie chart. Use the selection list to choose the item for which to change the font, then click the ellipsis (…) button to select the desired font type from the list of available fonts currently installed on your PC.
Axis (for graphs only)
x Automatic Scaling - By default, the program uses the Automatic Scaling options for setting the X and Y-axis minimum, maximum, and increment values. To customize an axis, turn the check mark off and enter the desired values for the minimum, maximum, and increment. If desired, you can customize a single axis while leaving the other in the Automatic Scaling mode.
x Log Scale - Place a check mark in this box to use a log scale for this axis. You can use a log scale for one or both axes.
Grid (for graphs only)
x X-Axis - Place a check mark in this box to view grid lines corresponding to the X-Axis labels.
x Y-Axis - Place a check mark in this box to view grid lines corresponding to the Y-Axis labels.
x Line Color - Use this selection list to define the color to use for both axes grid lines. x Line Style - Use this selection list to define the line type (solid, dashed, etc) to use for
both axes grid lines.
x Fill Color - Use this selection list to define the color to use for background fill within the plotting boundaries of the graph.
x Save as Default - Place a check mark in this box to save the current grid settings as the default for subsequent graphs.
Note: You can specify to use grid lines for one or both axes.
Display (for pie charts only)
x Data Labels - Allows you to annotate the pie-charts with percentages, labels, or both. x Chart View - Allows you to generate a 3D-view pie chart.
x Legend Location - Allows you to place the legend (if any) on the left, right, top, or bottom of the pie chart.

3.5
FlexUnits
Unit flexibility is available from almost anywhere within Haestad Methods’ software, including elemental dialogs, and the FlexUnits Manager.
3.5.1 Set Field Options
Most dialogs permit you access to FlexUnits, which allow you to set such options as the units, rounding, and scientific notation for any field in the dialog.
To set the display options for a unitized attribute:
1. Right-click the field and select Properties from the pop-up menu. The Set Field
Options dialog will appear.
2. Set the options you want for your units.
3. Click OK to set the options for the field, or Cancel to leave without making changes. 4. Depending on the type of unit you are working with, you will be able to change the
following characteristics: Units
Display Precision Scientific Notation
3.5.2 Units
Units are the method of measurement displayed for the attribute. To change units, click the choice list, then click the desired unit. The list is not limited to either SI or US customary units, so you can mix unit systems within the same project.
FlexUnits are intelligent - the units actually have meaning. When you change units, the displayed value is converted to the new unit, so the underlying magnitude of the attribute remains the same.
For example, a length of 100.0 feet is not converted to a length of 100.0 m or 100.0 in. It is correctly converted to 30.49 m or 1200.0 in.
3.5.3 Display Precision
The precision setting can be used to control the number of digits displayed after the decimal point, or the rounding of numbers.
Number of Digits Displayed After Decimal Point
Enter 0 or a positive number to specify the number of digits after the decimal point.
For example, if the display precision is set to 3, a value of 123.456789 displays as 123.457. This works the same regardless of whether scientific notation is active.
Rounding
Enter a negative number to specify rounding to the nearest power of 10. (-1) rounds to the nearest 10, (-2) rounds to the nearest 100, and so on.
For example, if the display precision is set to (–3), a value of 1,234,567.89 displays as 1,235,000.
Display precision is for numeric formatting only and will not affect calculation accuracy.
3.5.4 Scientific Notation
Scientific notation displays the number as a real number beginning with an integer or real value, followed by the letter "e" and an integer (possibly preceded by a sign). Click the field to turn scientific notation on or off. A check will appear in the box to indicate that this setting is turned on.
Scientific Notation is for numeric formatting only and will not affect calculation accuracy.
3.5.5 Minimum and Maximum Allowed Value
Minimum and maximum values are used to control the allowable range for an attribute, and are used for validation of user input. For example, some coefficient values might typically range between 0.09 and 0.20. A frequent user input error is to misplace the decimal point when entering a value. If you enter a number that is less than the minimum allowed value, a warning message will be displayed. This helps reduce the number of input errors.
28 Chapter 3 – Project Settings You may change this number in cases where you find the default limits too restrictive.
These allowable minimums and maximums are only available for certain parameters.
3.5.6 FlexUnits Manager
The FlexUnits Manager, which can be accessed by selecting Tools\FlexUnits, allows you to set the parameters for all the units used. The dialog consists of the following columns: x Attribute Type – Attribute measured by the unit.
x Unit - Type of measurement displayed. To change the unit of an attribute type, click the choice list and click the unit you want. This option also allows you to use both US customary and SI units in the same worksheet.
x System - Set the system of units. Click the system column for the desired unit, and a button should appear. Click the button, and set the unit system to US or SI.
x Display Precision - Rounding of numbers and number of digits displayed after the decimal point. Enter a negative number for rounding to the nearest power of 10: (-1) rounds to 10, (-2) rounds to 100, (-3) rounds to 1000, and so on. Enter a number from 0 to 8 to indicate the number of digits after the decimal point. This feature works the same whether scientific notation is on or off.
x Scientific Notation - Display numbers in scientific notation. Click the field to turn scientific notation on or off. If it is turned on, a checkmark appears in the box.
Notes: The display units can also be changed from several other areas in the program, and any changes are project-wide. For example, if length is changed from units of feet to meters, all pipe dialogs will display length in meters. If you change the units in the pipe dialog from meters to yards, the FlexUnits Manager will indicate that length is in yards.
FlexTables have the ability to use localized units, which are maintained separately from the current project settings. This allows you to create reports using units that differ from the ones currently active.
3.6
Quick Culvert Calculator
The Quick Culvert Calculator dialog is convenient for solving various culvert design problems. It provides quick solutions when detailed hydrological or site design scenarios are not needed.
1. To use the calculator, select one of the following Solve For properties: Headwater
Discharge Size
3. Select the Solve button to calculate the Solve For property and other exit results.
To access the Quick Culvert Calculator, select Worksheet\Create\Quick Culvert
Calculator from the pull-down menu.

The tabs at the top of the dialog show the location properties that can be entered or computed. These properties include:
x Watershed x Headwater x Tailwater x Grades
The lower part of dialog is used for managing culvert components, culvert design trials, and roadway profiles for computing overtopping.
x Design/Analysis - The Design and Analysis radio buttons located at the left-center of the dialog allow you to change between the two modes.
Design Mode - In design mode the individual culvert design trials you create are listed in the lower right area of the dialog. The command buttons to the left of the list allow you to create, open, duplicate, or delete culvert design trials. Data for any selected design trial is entered using the Culvert Design Trial dialog. The Solve All button calculates results for each individual design trial using the location data from the upper half of the Designer/Analyzer dialog.
Analysis Mode - In Analysis mode the weir element and culvert components for the embankment cross-drain system are listed in the lower right area of the dialog. The command buttons to the left of the list allow you to create, open, duplicate, or delete culverts. Data for any selected culvert is entered using the Culvert Component dialog. Data for the weir element is entered using the Overtopping Component dialog. The Solve All button calculates the cross-drain system using all the listed culvert components together using the location data from the upper half of the
Designer/Analyzer dialog.
In Design mode, the Weir element for computing the overtopping component is unavailable. In Analysis mode, the Headwater and Grades tabs are unavailable.
The Copy Design button lets you select an existing culvert design trial (created in design mode) to copy as a new culvert component. This button is only available in Analysis mode.
30 Chapter 3 – Project Settings
3.7.1 Watershed Tab
The first tab sheet of the Culvert Designer/Analyzer dialog allows you to enter the watershed information.
Three methods are available: x Peak Discharge Method x Rational Method
x SCS Peak Discharge Method
In Analysis mode, use the pulldown menu located at the upper-right of the dialog to select the type of storm to solve for: Check or Design Storm, or Overtopping.
The Check Storm / Design Storm / Overtopping pulldown menu is only visible when the Culvert Designer/Analyzer dialog is in Analysis mode.
Peak Discharge Method
The Peak Discharge method for watershed data entry is a quick and easy way to specify the discharge requirements for the culvert.
x Design Peak Discharge - Enter a peak discharge to use for the design storm. x Check Peak Discharge - Enter a peak discharge to use for the check storm.
Simply right-click any CulvertMaster table to access the new Copy-to-Clipboard feature. This allows you to place the table information in the Windows Clipboard to be used in other Windows applications.
Rational Method
The rational method solves for peak discharge based on the area, rational coefficient, and rainfall intensity for the watershed.
Subwatershed Information:
x Area - The surface area of the subwatershed. In the Rational Method, the subwatershed area(s) are used in conjunction with total watershed area to calculate the weighted rational coefficient.
x C (Rational Coefficient) - A unitless number between 0 and 1 that represents the ratio of rainfall volume over a watershed to the volume of discharge from the watershed.
Total Watershed Information:
x Total Area - This is the sum of the areas in the subwatershed spreadsheet. It is a non-editable value.
x Weighted C - This is the weighted rational coefficient computed from the subwatershed spreadsheet. It is a non-editable value.
