Salinization map 2014 - eastern coastal area (m-mv)

The map shows the depth of the 6 ?m interface in meters relative to ground level. This interface can be regarded as the interface between fresh and saline groundwater. By visualizing the map together with the data points, you know where measurements were taken and where interpolation took place. The map is the result of electromagnetic measurements carried out from the air in April 2014. The resistance of the subsurface was determined. The 6 ?m interface was derived from this. Resistivities (or resistances) of the subsoil less than 6 ?m can almost always be attributed to the presence of brackish or saline groundwater. The map is indicative and gives a global picture of the spatial distribution of saline and non-saline sediments in the eastern coastal plain. To know the local salinity distribution and lithological variation in detail, further research by the end user is necessary.

lineage https://www.vmm.be/publicaties/verziltingstoestand-van-het-oostelijk-kustgebied In april 2014 voerde de VMM metingen uit aan de oostkust om de verziltingstoestand van het grondwater te bepalen. De verdeling tussen zoet en zout grondwater werd al eens in kaart gebracht in de jaren 1960 en 1970. Dat is toen bekendgemaakt via de verziltingskaart. De helikoptermetingen tonen op het eerste zicht een ingewikkelde verdeling van zoet en zout grondwater. Wanneer echter dichterbij wordt gekeken, is een verband merkbaar met het soort bodem, de topografie en het zoutgehalte van de waterlopen.
