WEAP: Water Evaluation And Planning System User Guide (for WEAP 21)

Jack Sieber, Annette Huber-Lee, Paul Raskin, David Purkey

The Water Evaluation and Planning System (WEAP) aims to incorporate concerns about allocation of limited water resources, environmental quality, and sustainable water use into a practical tool for water resources planning. 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, as well as 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.

Polestar: System Manual for Version 2000

Paul Raskin, Charles Heaps, Jack Sieber, Eric Kemp-Benedict

The PoleStar System provides a flexible and user-friendly framework for building and assessing alternative development scenarios at regional, national, and global scales. It is an adaptable accounting and model-building framework designed to assist the analyst engaged in sustainability studies—not a rigid model reflecting one particular approach to environment and development interactions. With PoleStar, analysts can customize data structures, time horizons, and spatial boundaries—all of which can be expanded or altered easily. They can also introduce new variables, indicators and relationships to match their needs. The system can synthesize information generated from formal models, existing studies, or any other sources upon which the user wishes to draw.
