Extension of the Hydrogeologic Information System
Use of a powerful Data Base System Management (Access is limited about storage capacity and data security)
Integration of a statistic module for designing graphs using some of the data base’s stored
Decision Support System (DSS)
INTEREST OF THE HYDROGEOLOGIC INFORMATION SYSTEM
Possibility of generalization of this system to the whole Tunisia
A Data Bank with a maximum of data about region’s feature (hydrological, hydrogeological, environmental, socioeconomic, meteorological,soil, GIS data…)
Regroup and organize data in the same frame. The scatting of the hydrogeological data about the catchment area will be a hurdle behind researches
Update will be very easy since data will be centralized
Simulation of water inflow in the catchment
Conception allowing making additions of new frames and modules
We can manage a SHP files without using ArcView
SUMMARYSUMMARY
Geographic database: 33 layers SHP and 3 raster data
Land use map Iso-salinity, iso-piezometric and iso-depth map
Hydrogeological database: Information about 1544 wells (depht, standing water level, salinity,…) Information about the water table (phreatic and profond) Information about nodes:
Lake, dam…Observation well, bore hole…
Socio-economic database: socio-economic dynamic (population, migration, demography increases…)
Vectors layers and raster data technical report
Hydrological technical report
Determination of the inputs user in WaterWare
