Presentation Overview 1.GIS and database 2.Modelling i.MOHID modelling system ii.Case study: Trancão basin a)Progress b)Future work

Geographical Information System  Field data: Storage Storage Treatment Treatment Analysis Analysis  Georeferenciation  Web sharing

Project GIS allows to…  Systematize experimental data  Share results on the Internet  Search and query information  Model results visualisation and comparison with field data

MOHID Modelling System River Network Surface Water (ocean, estuaries, reservoirs) LAND (basins, aquifers) GUI (Graphical User Interface) GIS (basin, bathymetry creator)

MOHID Applications
