Groundwater Vulnerability to Pollution R index map (Net Recharge) in Catalonia according to DRASTIC
Net recharge map expressed as an index value according to DRASTIC ranges from 1 to 10, being 10 the net recharge greater than 500 mm and 1 the recharge less than 50mm.
Net recharge map is based on the SIMPA hydrogeology distributed model developed by the Agriculture Ministry of Spain. In addition, these data have been correlated with other available data: the pan-EU groundwater recharge map for DRASTIC assessment in the framework of the GeoERA project HOVER (WP7).
