In Talsim-NG, a river basin model is setup according to a modular principle. All relevant objects and processes of the water resources system are represented by system elements. These can be linked together as building blocks to represent the entire system including its interactions.

Each system element has specific properties and methods, is able to process certain input variables and provides specific output variables (see model concept). The following table gives an overview of all system elements in Talsim-NG with their most important properties/methods as well as input and output variables:
