Description of the System Elements

Navigation
| |

In Talsim-NG, a river basin model is setup according to a modular principle. All relevant objects and processes of the water management system are represented by system elements. These can be linked together like building blocks to represent the entire system with 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
natural/urban Catchment Area	Precipitation Temperature Evaporation	Soil properties/ proportion of paved areas Discharge formation Discharge distribution Discharge concentration ...	Surface drainage Basic outflow Total outflow ...
Introduction 40px	Water entry into the system	Outflow
Transport Route 40px	Inflow	Translation Retention	Outflow
Consumer 40px	Inflow	Consumption behavior Subsidy from other areas Reintroduction into the system	Reintroduction grant Total outflow
