FRESHEM Zeeland (starting page)
Description
In October 2014, the research programme FRESHEM Zeeland (FREsh Salt groundwater distribution by Helicopter ElectroMagnetic survey in the Province of Zeeland) was launched on behalf of the Province of Zeeland, Rijkswaterstaat, Het Rijk (Deltafonds), Evides, the Scheldestromen water board, ZLTO, the Flemish-Dutch Scheldt Commission and the municipalities of Zeeland. The implementing knowledge parties Deltares, TNO and the German Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) contribute to the research aspect of the programme and the scientific products. The aim of FRESHEM Zeeland is to develop an approach for producing a three-dimensional chloride distribution of groundwater in the Province of Zeeland using electromagnetic helicopter measurements (HEM). This approach uses already available information on the geology and knowledge of the groundwater system.
The result consists of 3 parts:
1. 3D result. The three-dimensional distribution of groundwater chloride concentration with a horizontal resolution of 50*50 m2 and a vertical resolution of 0.5 m.
2. 2D result. For each flight line, a chloride concentration profile with a horizontal resolution of (approximately) 4 metres.
3. Border area maps. For the limits 150, 300, 1000, 1500, 3000 and 10000 mg Cl/l, the depth of the interface has been determined in relation to NAP and ground level.
