Welcome to WSIMOD

WSIMOD stands for the Water Systems Integrated Modelling framework.

The terrestrial water cycle is a highly interconnected system where the movement of water is affected by physical and human processes. Thus, environmental models may become inaccurate if they do not provide a complete picture of the water cycle, missing out on unexpected opportunities and omitting impacts that arise from complex interactions. WSIMOD is a modelling framework to integrate these different processes. It provides a message passing interface to enable different subsystem models to communicate water flux and water quality information between each other, and self-contained representations of the key parts of the water cycle (rivers, reservoirs, urban and rural hydrological catchments, treatment plants, and pipe networks). We created WSIMOD to enable a user greater flexibility in setting up their water cycle models, motivated by the abundance of non-textbook water systems that we have experienced in industry collaboration. The WSIMOD Python package provides tutorials and examples to help modellers create nodes, connect them with arcs, and create simulations.
