2 WEAP Highlights Integrated water resources planning system. Integrated water resources planning system. GIS-based, graphical drag & drop interface. GIS-based, graphical drag & drop interface. Basic methodology: physical simulation of water demands and supplies. Basic methodology: physical simulation of water demands and supplies. Additional simulation modeling: user-created variables and modeling equations. Additional simulation modeling: user-created variables and modeling equations. Scenario management capabilities. Scenario management capabilities. Links to spreadsheets & other models Links to spreadsheets & other models

3 WEAP Capabilities Can do High level planning and strategic analysis at local, national and regional scales High level planning and strategic analysis at local, national and regional scales Demand management Demand management Water allocation Water allocation Cannot do Daily operations Daily operations Least-cost optimization of supply and demand Least-cost optimization of supply and demand

4 Examples of Analyses –Sectoral demand analyses –Water conservation –Water rights and allocation priorities –Groundwater and streamflow simulations –Reservoir operations –Hydropower generation –Pollution tracking –Ecosystem requirements

5 Selected Projects California California –Impacts of climate change and other stressors on ecosystem services Volta and Syr Darya Volta and Syr Darya –Food and environmental security China China –Providing a basis for cooperation/negotiation between Beijing and upstream water users South Africa South Africa –Moving towards equity in water use

6 …& Adaptation… Alternative baseline scenarios can examine vulnerability of water supplies to different demographic, technological, & climatalogical/hydrological futures. Alternative baseline scenarios can examine vulnerability of water supplies to different demographic, technological, & climatalogical/hydrological futures. WEAP for Vulnerability… Alternative policy scenarios can explore demand and supply management options for adapting to future vulnerability. Alternative policy scenarios can explore demand and supply management options for adapting to future vulnerability. Implications for the multiple and competing demands on water systems. Implications for the multiple and competing demands on water systems. Implications of policies can be evaluated (ability to meet water needs, hydropower availability, pollution loadings, costs, etc.) Implications of policies can be evaluated (ability to meet water needs, hydropower availability, pollution loadings, costs, etc.)

7 Schematic View Click and drag to create a new demand site

8 Data View Data is displayed numerically and graphically

9 Results View Results can be displayed in wide range of formats and scales

10 Overviews Favorite charts can be selected to give quick overviews

11 Sectoral Water Demands Irrigation Livestock Mining Industrial Commercial Ecosystems Domestic Total Water Demand Major Cities

12 Illustrative Demand Structure Agriculture Industry Municipal Cotton Rice Wheat... Electric Power Petroleum Paper... South City West City... Irrigation... Cooling Processing Others Single Family Multi-family... Furrow Sprinkler Drip Standard Efficient... Kitchen Bathing Washer Toilet... SECTOR SUBSECTOR END-USE DEVICE

13 Supplies Rivers Rivers Groundwater Groundwater –storage capacity –maximum monthly withdrawal –natural recharge Diversions (e.g. canals, pipelines) Diversions (e.g. canals, pipelines) Reservoirs Reservoirs Other (e.g. desalination) Other (e.g. desalination)

14 Hydrology Read-from-File Method Historical or synthetic data, imported from data files Historical or synthetic data, imported from data files Water-Year Method Create a series of water year types from very dry through normal to very wet (5 types). Create a series of water year types from very dry through normal to very wet (5 types). For each scenario year specify its type. For each scenario year specify its type. Use to examine alternative climate scenarios. Use to examine alternative climate scenarios.

15 Hydropower Capacities, efficiencies, and other properties of power generation
