Talsim-NG is an advanced hybrid hydrological/hydraulic watershed model designed to tackle a wide range of hydrological concerns, from flood management to drought assessment. This scalable and modular software allows for customizable configurations based on specific water management needs, accommodating everything from small catchments of less than 10 km² to large river basins exceeding 3,000,000 km², such as the entire Nile basin.

Core features of Talsim-NG include precipitation-runoff simulation (with snow modeling), hydraulic modeling of structures, and complex atmospheric, vegetation, and soil interactions. The software supports flexible time-step simulations, ranging from one minute to a month, and offers various functionalities like groundwater modeling, wetland modeling, and calculations for plant water requirements and irrigation needs.

The system is backed by a comprehensive online documentation resource, continuously updated to provide users with the latest operational information and tutorials. Talsim-NG is an essential tool for effective water resource management, accommodating both professional and research-oriented applications.
