Sint Jansbeek stream restoration

Iv played a key role in the restoration of the Sint Jansbeek, a project aimed at tackling drought and increasing resilience to extreme rainfall across the region. Flowing from the village to the River Meuse, the stream has been transformed from a straight, purely functional watercourse into a naturally meandering stream where surface water, groundwater and ecological processes are in better balance.

Iv developed hydrological models, designed fish passes to support the migration of species such as the weatherfish, and delivered technical solutions for weirs and water level management.

The project involved a range of challenges, including balancing the competing interests of agriculture and nature, technically reconciling measures to address both drought and waterlogging, and carefully integrating the restored stream into a variety of landscapes. In addition, the incorporation of ecological corridors within a landscape that respects its cultural heritage required a fully integrated design approach.

A key technical challenge was increasing the length of the stream by reintroducing meanders, significantly enhancing its water storage capacity. This reflects the principle of water and soil as guiding factors in spatial planning, with the water system forming the basis for the overall design. By combining land and water engineering, landscape design, hydrology and urban water management, the project has created a stream that supports biodiversity while remaining practical to manage for the regional water authority.

The restoration of the Sint Jansbeek delivers multiple benefits, including improved water storage, enhanced ecological value and an attractive, functional public space. The stream now serves as an ecological corridor and is a strong example of blue-green infrastructure, where water, nature and the living environment reinforce one another.

By creating a longer, more natural watercourse, the stream is better able to cope with the impacts of climate change, including prolonged periods of drought and more intense rainfall. The project successfully combines engineering and nature to demonstrate how Iv delivers solutions that are functional, sustainable and visually well integrated into their surroundings. Through its multidisciplinary approach, Iv has contributed to a resilient, future-ready water system that maintains the balance between people, nature and cultural heritage.
