Hydrogeologic Information System
Hydrologic data Hydrogeologic data Environmental data Meteorological data
Management of the catchments area

Interest of the Hydrogeologic Information System
A Data Bank with a maximum of data about region’s feature (hydrological, hydrogeological, environmental, 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
