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 inclusing 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:

Element	Important loads	Properties / methods	Element output
Sub-basin	Precipitation Temperature Evaporation	Soil properties/imperviousness Runoff generation Runoff distribution Runoff concentration ...	Surface runoff Baseflow Total discharge ...
Point source		Water input into the system	Runoff
Transport reach	Inflow	Translation Retention	Runoff
Consumer	Inflow	Consumption behavior Contribution from other areas Return flow into the system	Return flow Contribution Total discharge
Diversion	Inflow	Diversion rule	Two outflows
Reservoir	Inflow optional: Precipitation Evaporation	Storage rating curve Storage-surface rating curve Capacity of operational equipment Operating rules (Infiltration properties) ...	Releases Storage Water level
System Outlet	Inflow
