The Netherlands has a long history of water management. To operate and design our water system in a changing environment, we need computer simulations. Deltares is currently developing the next generation water resources software Ribasim, which will be used in the Dutch National Hydrological Model. The core is written in Julia on top of the SciML stack.
In this talk we will show the design of the application and discuss strengths and difficulties of Julia and its ecosystem for such a use case.
Ribasim replaces several command line applications written originally written in the 80’s in Fortran. Rather than simply rewriting them in Julia, we strived to make it more hackable and to make use of advances in solvers, automatic differentiation, file formats and interfaces.
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.
