wflow is a distributed hydrological model platform that currently includes a number of models models. The models share the same structure but are fairly different with respect to the conceptualisation. The shared software framework includes the basic maps (dem, landuse, soil etc) and the hydrological routing via the kinematic wave. The Python class framework also exposes the models as an API and is based on the PCRaster/Python version 4.1. Links to BMI and OpenDA (www.openda.org) have been established. All code is available at github (https://github.com/openstreams/wflow/) and distributed under the GPL version 3.0.
The models are programmed python using the pcraster python extension. As such, the structure of the model is transparent, can be changed by other modellers easily, and the system allows for rapid development. In order to run the model both PCRaster 4.* and Python 2.7 are needed. At the moment only 64 bit versions are actively supported.
