Belgium – Survey services – ECOHYDROLOGICAL STUDY KIKBEEK and SAC MECHELSE HEIDE

Opportunity description

The reason for initiating the ecohydrological study is the stability problems in the Kikbeek lake, as a result of which the water-level increases aimed at achieving the conservation objectives currently cannot proceed. The subject of the ecohydrological study is to investigate the effects of higher water levels (than the current levels) in the Kikbeek quarry on the surrounding groundwater-dependent vegetation. In addition, it will be investigated which supplementary rewetting measures in the Habitats Directive area of Mechelse Heide, Ziepbeek Valley, Neerharerheide and Asbeek are necessary to achieve a climate-resilient system. The aim of the study is to investigate the impact on groundwater levels and the ecological boundary conditions resulting from increases in the water level of the Kikbeek lake and from hydrological restoration measures in Mechelse Heide, Ziepbeek, Neerharerheide and Asbeek. This must lead to maximising the restoration and conservation of groundwater-dependent vegetation. The objective is to achieve climate-resilient system restoration without jeopardising critical infrastructure (such as the E314 motorway) and the long-term stability of the Berg quarry and the Kikbeek lake. The preparation of hydrological and ecological model predictions must serve to investigate scenarios for water-level increases in the Kikbeek lake and to develop and evaluate the development of wetland nature in the Habitats Directive area of Mechelse Heide.
