Wflow

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.

Documentation

See stable or
dev for the documentation.

Installation

For the installation enter the Pkg REPL by pressing ] from the Julia REPL, and then

pkg> add Wflow

A more detailed description, including a development install, is available
