FREEWAT aims at serving as pre- and post-processor for processing of hydrological time-series to maximize sensor gathered information (baseflow extraction, resampling, etc.), water quality data, solving groundwater flow, contaminant transport in saturated and unsaturated condition, calibration of numerical models, optimization of water supply systems, management of water for agricultural purposes. FREEWAT helps in building shared awareness on the value of water. It may be used by public authorities for the implementation of river basin management plans using the participatory approach (as done in 14 case studies in the project) – or by companies for providing readily usable models on contaminated sites to agencies, instead of only reports.
