Abstract:
|
"Being able to assess the ability of a catchment to satisfy potential water demands is crucial for water resource planning. In this study, a scenario analysis approach was used in combination with the Water Evaluation and Planning (WEAP) model, to assess the impacts of possible future demands on the water resources of the Olifants River catchment, South Africa. The WEAP model was used to simulate water demand in five different sectors; rural, urban, mining, commercial forestry and irrigation. For each scenario the model provided data on unmet demands and the impacts on river flow. The implications of construction of new water infrastructure and improved demand management were assessed. The study illustrates the value of scenarios linked to simple modeling tools, to provide insight for resource planning."
