Introduction GIT Geology and Information Technology SID&GRID Project: Simulazione e sistemi IDroinformatici per la Gestione delle Risorse IDriche Funded under POR FSE 2007-2013 by Regione Toscana Started in April 2010 and concluded in March 2013 Scientific partnership: Dep. of Mathematics, University of Firenze Land Lab, Scuola Superiore S.Anna, Pisa CNR--ISTI, Pisa End-users partnership: Ingegnerie Toscane S.r.l., Pisa Autorità di Bacino Pilota del Fiume Serchio, Lucca H2O Ingegneria S.r.l., Pisa See also: Rossetto, R., Borsi, I., Schifani, C., Bonari, E., Mogorovich, P., Primicerio, M., 2010.

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.

Anna) [hydrological supervision and testing] Claudio Schifani (formerly CNR ISTI) [GIS interface and DB] Scientific supervisors: M. Primicerio (Università degli Studi di Firenze) E. Bonari (Scuola S.

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.) Input and output data may be published on the web via WMS
Software capability (2) SID&GRID allows to know the distribution of the water resource in space and time 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
Software capability (3) Assessment of impacts on the hydrological cycle caused by climate change and or urban sprawling Simulations of recharge variations to aquifers in areas run by fire. How urban sprawling impact recharge to the aquifers?ce management and planning Example: run off generation on a slope
Software capability (4) Asssessment pumping wells impact in sensitive areas 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) Full 3D solution (+ evaporation, transpiration, pond, seepage flow)
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; Canopy interception: the net rainfall rate reaching the soil surface.
Software architecture: DB and GIS interface Tight coupling approach

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 (c) a rich set of GIS plug-in to be used in synergy with SID&GRID
Proposal for HORIZON 2020 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.)
