The Kathagerbroek area provides habitat for many rare botanical species, which largely depend on upward seepage occurring in the area. A groundwater flow model of the area leads to a better understanding of the local hydrological conditions and estimates the source of the upward seepage, which is a crucial information for preserving this nature reserve.
Building a groundwater flow model of the Kathagerbroek in South Limburg
Supervisors: George Bier, Roel Dijksma
The main goal of the research is to build a steady-state groundwater flow model of the area around Kathagerbroek, which is a protected nature reserve providing habitat for many rare botanical species. These species are very sensitive towards a change in local hydrological conditions, especially upward seepage. A projected motor-way close to the Kathagerbroek area could have a negative impact on this seepage process and therefore a numerical modelling of the groundwater flow in the area is needed. For a better understanding of the groundwater flow around the Kathagerbroek a regional groundwater flow model is built. Using information provided by this regional model a more detailed local groundwater model can be set up. This local model enables to focus in more detail on the local hydrological conditions and also to estimate the upward seepage rate in the Kathagerbroek area.
