Salinisation map 2014/2017 optimistic (mTAW)

Description

The map, based on the helicopter measurements of 2014 and 2017, gives an optimistic estimate of the depth of the interface between fresh and brackish groundwater in meters TAW. Taking into account the uncertainty of the measurements, two versions of the salinisation map were drawn up: 1. A conservative estimate of the depth of the interface based on a 95% probability of fresh groundwater being found above this interface. 2. An optimistic estimate of the depth of the interface based on an 89% probability of fresh groundwater being found above this interface. Fresh water means conductivity less than 2000 μS/cm. It is advisable to consult both interfaces in order to estimate the freshwater distribution at a particular location. In addition, the data points (‘salination map_2014_helicopter measurements’ and ‘salination map_2017_helicopter measurements’) are available in order to identify where effective measurements were made and where interpolations were made. The data points are on flight lines where a vertical profile can be consulted with a view of the bulk resisitiveit for the measurements from 2014 and with a view of the salinity, the bulk resistivity, the lithology and the stratigraphy for the measurements from 2017. On the profiles, the boundary between fresh and brackish (optimistic and conservative) and between brackish and salt groundwater is visible. The boundary between brackish and saline groundwater is defined as 25000 μS/cm.
