The Material Designer lets the user maintain and edit the material database of UnSat Suite. Both the materials comprising the profile and the pesticides/contaminants leaching through the soil are stored in the material database.

You can create new materials for each model with the Material Designer. To begin, open the dialog box.

Materials are stored separately for every model. To use the Material

Designer, select the name of the model from the Model list. Then, select

the layer type from the Material Category list. Finally, select the material from the Material list.

Create a new profile using an existing template or create a new template, and edit it until you are satisfied that it will suit your needs.

To create a new template:

1) From the File menu, ) Save Project. (this is necessary to save the template)

2) <right click> on the profile in the Project Tree 3) ) Save As Template

4) ) [Yes]

5) Type a unique name for this profile template in the Confirm Name dialog box.

6) ) [OK] to save a template.

To open the dialog box:

1) From the File menu click Settings

For VS2DT, PESTAN and VLEACH in the Material Designer all soils are structured according to the widely used USDA-SCS classification scheme into the material groups (categories). For the HELP model all materials are grouped according to the functional categories of landfill materials. Within each category the user may add an unlimited number of soil records.

The following chart illustrates the components of the 12 main material categories for the VS2DT, SESOIL, PESTAN and VLEACH models.

yellow color

Sand

Between 85-100% sand, under 10% clay, under 15% silt. yellow color

Loamy Sand

Between 70-90% sand, under 15% clay, under 30% silt.

turquoise color

Sandy Loam

Between 42-85% sand, under 20% clay, under 50% silt.

turquoise color

Sandy Clay Loam

Between 45-80% sand, between 20-35% clay, under 27% silt.

The soils were composed of silt (2-50 µm), clay (<2 µm), and sand (>50

µm).

The view of the Material Designer dialog box differs for the HELP model. The Design Layer Permissions frame, which does not show up for the rest of the models, displays features which pertain to specific HELP material categories.

The custom thickness refers to the thickness of the layer and can be edited directly in the Material Designer or can be edited through Layer

Properties. Manufactured materials, such as geomembrane liners, have

set thicknesses which can not be altered. The interface allows setting

Drainage parameters for Lateral Drainage and Geotextiles and Geonets layers in HELP. The specific drainage parameters of the layer

can be specified in layer properties while running the project. Also in HELP, the user can specify the initial moisture content of some layer categories. If custom initial moisture content for the layer is checked, the user can specify this parameter through the layer properties.

To add new material to the Material Designer, use one of the existing green color

name to a unique name for the new material in the Name box. Then, enter a description of your new material in the Description box. In the Material number box you can enter an index number. For the HELP model, material numbers 1 - 42 are used by the default materials. New materials for the HELP model should begin at 43. For the remaining models, numbering can begin at one. This number is for filing purposes only and does not change the properties of the material. It is important, however, to make sure that the model numbers do not repeat. Each new material, within a model, should have a new number.

In the Thickness box you can enter the default thickness of the material. Every time you enter the material into a profile, it will be entered at this thickness. Click the accompanying units for the thickness in the

Thickness units box.

The Soil Parameters tab will display all the editable properties of the soil. You can specify the materials default property values in the appropriate boxes in the Value column. You can also click the accompanying units from the Units column.

If you are designing or modeling for the VS2DT model, there will be additional tabs for Transport Parameters and Initial Conditions. To edit these parameters click the appropriate tab. Type in the new value in the appropriate boxes in the Value column. You can click and select other units from the Units column if you have your data in different units. When you have completed specifying the properties of the new material, ) [Add].
