The SEMEAU modelling tool is designed to conjunctively simulate surface and groundwater both in terms of quantity and quality.

The SEMEAU project is above all focused on developing a tool adapted to the hydrosystems of European hills and medium mountains where the forest generally covers a substantial part of the catchment areas. This innovative tool will thus be useful, usable and used within the scope of operational water resource management.
A useful tool
The SEMEAU tool will have a significant application extent as it relates to the surface and groundwater bodies located in the hilly and medium mountain areas representing approximately one third of the European space (Massif Central, Black Forest, Cornouaille, Bohemia, etc.). In terms of quality of water, it must take into account all the parameters deemed important in this type of context (chloride, nitrates, phosphates, etc.). The SEMEAU tool must in particular include the impacts of forest cover management on the groundwater resources as these regions are subjected to rural abandonment and namely an increase in the demand for fire wood.
Besides the technical aspects involved in modelling the functioning of hydrosystems, this will simulate land management scenarios by the local stakeholders in the dual aim of local development and water resource protection.
A usable tool
The SEMEAU tool must be adapted to the wide diversity of hydrological contexts encountered in hilly and medium mountain areas. It must therefore be compatible with different types of catchments. It should also be technically and cost effective.
A used tool
The SEMEAU tool, previously tested on the different sites (Volvic, Saint Etienne), will be specifically exposed to the local, national and European end users.
