Einsatzmöglichkeiten von Talsim-NG/en

Talsim-NG is the right tool for many different tasks:

• Rainfall-runoff simulations (both flood and long-term scenarios)
• River basin modelling and management
• Management of reservoirs, flood control reservoirs, dams or dam systems for various uses (water supply, flood protection, low flow augmentation, energy production, compliance with minimum releases, recreational use)
• Water quality simulations
• Coupling of water quantity and water quality considerations
• Dimensioning of water resource management facilities
• Operational use of Talsim-NG for water management in connection with a monitoring system

Talsim-NG includes the necessary tools for water resource analyses:

• Time series management
• Management of simulations and their results including result comparison
• Long-term simulations / short-term forecasts
• Request and output of arbitrary state variables
• Calculation of useful parameters such as balance values or probabilities

Atmosphere / Vegetation / Soil Interface for Crop Water Requirements and Irrigation

Sub-basin

Linkage of flow components

Surface and sub-surface flow components between elements are interconnected. If soil downstream is saturated, flow from the upstream cell is impeded:

• Backwater effects
• Surface flow accumulates from element to element

Nested modelling

A model within a model!

If necessary, sub-basins can be simulated with different resolutions and levels of detail within a large river basin model.

Participatory modelling / serious gaming

Talsim-NG as tool for capacity building:

1) Topic: Live interaction between water managers
2) Tool: Put operators in various positions

• upstream perspective, downstream perspective
• exposes stakeholders to different levels of dependencies
• shows effects with/without data sharing
• demonstrates effects with/without cooperation
• mimics flood / drought events

3) Activity: A group of water managers plays at the same time
