Deltares and Rijkswaterstaat took the initiative to establish a Numerical River Laboratory (RiverLab). The elements of this laboratory are based on the Delft3D FM Suite, and consist of a fully developed numerical modelling environment for hydraulic and morphological simulations on unstructured grids in 1D-2D-3D. The environment is open source, and may be downloaded by everyone to conduct experiments and test new model concepts. In doing this, we enable and stimulate the building of a modelling community, to share knowledge, ideas and insights in an interdisciplinary and interagency manner.

This website provides the platform for the availability and continuous development of the process-based, hydrodynamic and morphological model environment. It is based on the Delft3D-FM (Flexible mesh) software. Available is the software for 1D, 2D and 3D modelling. Some example-models are available.

The Numerical River Laboratory is developed within the context of the Netherlands Center for River Research (NCR) with financial support of Deltares and Rijkswaterstaat. The RiverLab is part of a bigger research initiative, called Rivers2Morrow: Working on the Future of our Rivers. This research initiative aims at improving understanding of the long term development of lowland rivers, concentrating on flow, morphology, ecology, governance and its interactions. It is a cooperation between the Ministry of Infrastructure and Water Management, Rijkswaterstaat, several universities, knowledge institutes and high-end consultancy firms. Rivers2Morrow aims at gaining knowledge to improve maintenance of lowland rivers and to improve policy decisions which often have consequences on the long time scale

Rivers2Morrow is the research program that is connected to NKWK-initiative taken by the Ministry of Infrastructure and Water Management. NKWK is a Dutch abbreviation which stands for: National Knowledge and Innovation Program on Water and Climate. See waterenklimaat.nl/research-tracks/rivers/?lang=en.
