Talsim-NG is a hybrid hydrologic/hydraulic river basin model. it is designed to capture all hydrological situations from flood to drought. The software concept is modulare and scalable, meaning that a water resources system can be tailored according to the actual needs. The spatial resolution has no limits. The temporal resolution as simulation time step can vary from one minute to one month. Talsim-NG was applied for watersheds < 10 km² up to river basins > 3,000,000 km² (e.g. entire Nile system).

Talsim-NG is based on an open, generic model architecture. With the available components, the user is able to simulate any water management system and management strategies.

This Wiki contains the official documentation of Talsim-NG.

This Wiki is constantly being maintained and expanded. Individual sections are still under construction.
