Wflow is a Julia package that provides a hydrological modeling framework, as well as several different vertical and lateral concepts that can be used to run hydrological simulations. It is a continuation of the work available here.

You can use Wflow in the following three ways.

  1. From Julia as a library. The Quick start describes how to install it, prepare an example model, and run a simulation.
  2. With the wflow_cli Command Line Interface. This way there is no need to install Julia, you can download a binary and run.
  3. Through the Basic Model Interface, which is a standardized interface to run the model that also makes it easy to couple other BMI enabled models to it.

Wflow can also be linked to the flood forecasting system Delft-FEWS. This is described in Run from Delft-FEWS
