Possible applications of Talsim-NG
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

Gridded or watershed oriented approach
Talsim-NG can be used for both gridded or watershed oriented concepts
gridded
watersheds
Atmosphere / Vegetation / Soil Interface for Crop Water Requirements and Irrigation
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
