Martijn Visser is a hydrologist at Deltares, where he focuses on integrated water resources management, as well as building open source software to support it. As an early adopter of the Julia programming language he’s been active in the open source community, helping to set up and maintain JuliaGeo and its packages, which aim to make it easier to work with geospatial data in Julia.
Session
We introduce two hydrological numerical models in Julia, developed at Deltares. Wflow is a distributed hydrological modelling platform, including different vertical and lateral concepts. Ribasim is a water resources model, solving the water balance equation for regional surface waters, allowing users to solve water allocation questions. We explain why we (re)wrote Wflow and Ribasim, which were originally coded in respectively Python and Fortran and discuss why we keep most processing in Python.
