Groundwater surface - GWO: GwFlur spacing [m]
Description
Knowledge of the location of the groundwater surface (GWO) is helpful for many questions in the context of site assessments. Their detection is only possible selectively at groundwater measuring points or other suitable groundwater outcrops. In the area, especially nationwide, prognostic estimates are possible. For Rhineland-Palatinate, a nationwide estimation of the average altitude of the groundwater surface was carried out using a stationary groundwater flow model. At the same time, the representation of groundwater levels is possible. In conjunction with the topographical elevation model, a forecast model of mean distances, i.e. an averaged depth of the groundwater surface below the surface of the terrain, is thus also available. Due to the very different temporal and spatial resolution of the input data used, their different scaling and non-congruent time windows of the data sets, the model results have only a very simplistic, prognostic character. It should also be borne in mind that seasonal groundwater fluctuations – especially in the solid rocks – can amount to several metres. In addition, groundwater levels have been falling in many regions since around 2003. Despite these limitations, however, the model results provide important guidance on a territorial scale. Further explanations on the procedure and methodology for the assessment of the groundwater surface in Rhineland-Palatinate can be found in Projektbeschreibung. The presented assessments of groundwater surface, levelling and groundwater level do not replace site-based on-site investigations.: Knowledge of the location of the groundwater surface (GWO) is helpful for many questions in the context of site assessments.
