PCDitch offers help

At Witteveen+Bos we work with partners to create sustainable water bodies and a safe environment in deltas, coastal and river areas. With rising sea levels, subsidence and changing climate, we face major challenges. This requires smart digital solutions, PCDitch offers help.


Both the PCLake model and the PCDitch model were developed by Jan Janse (Janse, 2005). Both models have been further developed by Witteveen+Bos, STOWA, NIOO-KNAW, Netherlands Environmental Assessment Agency and the WUR. PCLake has already been used successfully in several projects.
