Decision Support for Water Resource Policy in South Africa

The Department of Water Affairs and Forestry (DWAF) is responsible for the formulation and implementation of water policy and for supervising the provision of water services in South Africa.

DWAF recently set about reviewing decision support tools to replace the antiquated and poorly understood simulation models that they currently use to conduct assessments of their managed water resources systems.

SEI’s WEAP system was selected by DWAF as one of eight models in contention for replacing their current systems. In support of DWAF’s efforts to understand and appreciate the full capabilities of the WEAP system, SEI developed an application for a South African watershed and demonstrated the model’s utility by performing a sample analysis typical of DWAF water planning studies.

This case study was presented to an expert panel at a model-review workshop in Pretoria in May 2008.
