Abstract:
WEAPİ is a microcomputer tool for integrated water resources planning. It
provides a comprehensive, flexible and user-friendly
framework for policy analysis. A growing number of water professionals are
finding WEAP to be a useful addition to their toolbox of
models, databases, spreadsheets and other software. This introduction
summarizes WEAP's purpose, approach and structure. A
detailed technical description is available in a separate publication,
the WEAP User Guide.
Many regions are facing formidable freshwater management challenges.
Allocation of limited water resources, environmental quality
and policies for sustainable water use are issues of increasing concern.
Conventional supply-oriented simulation models are not
always adequate. Over the last decade, an integrated approach to water
development has emerged which places water supply
projects in the context of demand-side issues, water quality and ecosystem
preservation.
WEAP aims to incorporate these values into a practical tool for water
resources planning. WEAP is distinguished by its integrated
approach to simulating water systems and by its policy orientation. WEAP
places the demand side of the equation
- water use patterns,
- equipment efficiencies,
- re-use,
- prices and
- allocation
on an equal footing with the supply side
- streamflow,
- groundwater,
- reservoirs and
- water transfers.
WEAP is a laboratory for examining
alternative water development and management strategies.
WEAP is comprehensive, straightforward and easy-to-use, and attempts to assist rather than substitute for the skilled planner. As a
database, WEAP provides a system for maintaining water demand and supply information. As a forecasting tool, WEAP simulates
water demand, supply, flows, and storage, and pollution generation, treatment and discharge. As a policy analysis tool, WEAP
evaluates a full range of water development and management options, and takes account of multiple and competing uses of water
systems.
