Reeshof stream restoration

Iv played an important role in the redesign of the Donge in Reeshofweide, focusing on stream restoration and fish migration. The new meandering stream improves ecological connectivity and contributes to a more sustainable water system, with a better balance between surface water and groundwater. Iv was responsible for the design, calculations and a hydrological analysis of the future water management system. The calculations were carried out using SOBEK models, based on the hydrological boundary conditions provided by Waterschap Brabantse Delta.

One of the main challenges within the project was determining the dimensions of the stream. This required defining the appropriate cross-sections, the required bed resistance and the optimal flow distribution between the old and new courses of the Donge. Integration into the existing water system also required careful decision-making. The connections to existing watercourses and the location of flow control structures were therefore developed as an integrated part of the design to ensure a properly functioning water system. The principle of water and soil as guiding factors was an important design basis throughout.

The new meander contributes to a robust, climate-resilient water system. The stream not only improves water quality and biodiversity, but also provides better regulation of water levels in both wet and dry periods. This makes the project a strong example of a blue-green scheme in which water, nature and the living environment reinforce one another.

By integrating hydrological modelling and technical design, Iv has created a solution that performs well both ecologically and functionally. In this way, the project contributes to sustainability, habitat development and a future-proof layout of the area.
