Introduction (ctd.)

Final goal of the project

To develop a 3D physically based distributed hydrological model (surface/subsurface water) to be used as helpful tool by public bodies and/or private companies in order to simulate the whole hydrological cycle and perform spatial-temporal analysis for water management and planning

All the project was developed using open source and free codes. SID&GRID architecture is based on:

1. integration of a DBMS (Data Base Management System); 2. development of tools/toolbar into a GIS framework;

3. integration and development of groundwater (saturated and unsaturated zone) and surface water hydrological modeling codes in the GIS platform.

Software capability

A GIS platform as pre- and post-processing tool to simulate the

hydrological cycle

(in addition to standard GIS functionalities)

Model output can be analyzed and integrated with any other

GIS-based data (e.g. for urban planning, new infrastructure design, environmental assessment, etc.)

Software capability (2)

For each simulation a water budget and a

contour map of total head in the aquifer are produced

Data on discharge and head at selected locations of a surface water body may be produced

All the data produced may be used for taking informed and critical decisions in water resource management and planning

SID&GRID allows to know the distribution of the water resource

in space and time

Software capability (3)

Simulations of recharge variations to aquifers in areas run by fire.

How urban sprawling impact recharge to the aquifers?ce management and planning

Assessment of impacts on the hydrological cycle caused by climate

change and or urban sprawling

Software capability (4)

Example: Simulation of the expected drawdown at the end of a dry season or the groundwater head increase at the end of the recharge period

Software architecture: hydrological model

SID&GRID numerical core is composed by a set of numerical packages,

derived by the well-known

MODFLOW

“family” (U.S. Geological Survey):

the user can simulate the whole hydrological cycle or just parts of it (in

red:

tools specifically developed or adapted in SID&GRID).

1. Groundwater flow, activating one or more “stresses”: Effect of Well(s)

Interaction with River/Streams or Drains Direct aquifer recharge

Other boundary conditions (e.g. lake/sea interface) 2. Water flow in the unsaturated zone with two options:

1D infiltration model (with evapotranspiration)

Software architecture: hydrological model

3. Water flow in stream/river ( 1D Saint-Venant eq. (kinematic—wave approximation) and interaction of surface/subsurface flows.

4. Possibility to activate Local Grid Refinement(s) in selected areas of interest. 5. Overland flow.

6. New Jython algorithms (directly integrated in gvSIG) to compute: the PET (Potential Evapotranspiration) term;

Ongoing development

MARSOL FP7 project

TEA and S. S.Anna are partners of the ongoing R&D project MARSOL (Demonstrating Managed Aquifer Recharge as a Solution to water scarcity and Drought), Funded by EC under the FP7 Programme (section Environment Water Inno&Demo)

In particular, concerning SID&GRID:

Inclusion of SEAWAT<=> capability to simulate heat and solute transport in aquifer(s), useful to model:

(a) contamination plumes (b) well field protection areas (c) sewater intrusion

(d) geothermal plants (very low/low enthalpy) (e) ...

Ongoing development

Porting in QGis platform

(to be confirmed)

Using QGis (instead of gvSIG) as GIS platform for SID&GRID This might allow:

(a) a larger community of users

(b) a larger community of developers

A proposal under H2020 financial scheme has been recently submitted (April 8, 2014) Main goals:

(a) disseminating the use of SID&GRID around Europe (innovation & capacity building) (b) including additional capabilities (e.g. calibration, solute transport in unsat. zone, water management software)

Core group: TEA, Scuola S.Anna, TU Darmstadt

And other (14) partners from: Spain, Germany, Romania, Greece, France, Malta, Estonia, Ukreine, Slovenia, Turky, Czech Rep, UNESCO, …

Spin off services

TEA and Scuola S.Anna are proposing a series of activities (as market up-take of the research product)

1. CONSULTING

- Using SID&GRID to provide groundwater modeling services - Support for software installation

- Consulting and support in using SID&GRID 2. TRAINING

- Classroom courses and custom training classes 3. DEVELOPMENT and SOFTWARE MAINTANANCE - Consulting to develop new customized capabilities

- Integration with other in house activities (environmental monitoring, air pollution, landfills, soil remediation, etc.)
