Development of lookup tables of climate change impact
- n national water resources
What is lookup table
- f climate change impact?
Typical impact studies
1. Develop a detailed model 2. Develop a detailed climate scenario 3. Run the model 4. Analyze several simulation runs
Lookup table approach
1. Using a detailed model, run hundreds of simulations by changing climate conditions. 2. Develop a database of response to climate change (lookup table).
