WEAP Highlights
 Integrated water resources planning system.
 GIS-based, graphical drag & drop interface.
 Basic methodology: physical simulation of
water demands and supplies.
 Additional simulation modeling: user-created
variables and modeling equations.
 Scenario management capabilities.
 Links to spreadsheets & other models
WEAP Capabilities
Can do
 High level planning
and strategic analysis
at local, national and
regional scales
 Demand management
 Water allocation
Cannot do
 Daily operations
 Least-cost optimization
of supply and demand
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
Selected Projects
 California
– Impacts of climate change and other stressors on
ecosystem services
 Volta and Syr Darya
– Food and environmental security
 China
– Providing a basis for cooperation/negotiation between
Beijing and upstream water users
 South Africa
– Moving towards equity in water use
WEAP for Vulnerability…
 Alternative baseline scenarios can examine vulnerability of
water supplies to different demographic, technological, &
climatalogical/hydrological futures.
…& Adaptation…
 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 of policies can be evaluated (ability to meet
water needs, hydropower availability, pollution loadings,
costs, etc.)

Supplies
 Rivers
 Groundwater
– storage capacity
– maximum monthly withdrawal
– natural recharge
 Diversions (e.g. canals, pipelines)
 Reservoirs
 Other (e.g. desalination)
Hydrology
Water-Year Method
Read-from-File Method
 Create a series of water year
“types” from very dry through
normal to very wet (5 types).
 For each scenario year
specify its type.
 Use to examine alternative
climate scenarios.
 Historical or synthetic data,
imported from data files
Hydropower
Capacities,
efficiencies, and
other properties
of power
generation
Priority Allocation
of Water Resources
 Supply Priorities
Allocation Order
 Demand Preferences
Network
WEAP System Requirements
 Windows 95 or later
 32 MB of RAM (64 MB suggested)
 Imports from/exports to Excel and Word (not
required).
 Uses standard ArcView GIS “shape” files.
ArcView is not required.
