A 3d groundwater flow model is to be drawn from the region around Target. The model area is bordered by the Scheldt in the east and north and by the Durne in the south and southwest. All layers from the Quaternary layers t.e.m. will be charged the water-carrying part of the Paleozoic. This is an area with an area of ​​30 to 30km. The purpose of the model is to provide a clear picture of the groundwater flow in the different aquifers and through the aquitards. It is up to take into account aspects influencing this movement today. The groundwater flow model is intended as a single synthesis of the existing information of the area.
