Currently, in South Africa, there are various initiatives to look at water resources and water demand on a catchment scale. Many of these studies investigate water availability for the Basic Human Needs Reserve, Ecological Reserve and for licensing for other uses (see Pollard et al, 2002). Indispensably, computer models are being used for these studies.

A component of the WHiRL project in South Africa included looking at the integration of water services with catchment level water resources and infrastructure planning. As part of that work, the Resources, Infrastructure, Demand and Entitlement (RIDe) methodology was developed and applied (Moriarty et al, 2004).

This paper discusses use of water resources modelling tools as part of the application of the RIDe methodology, in order to assess possible management scenarios for water resources in the Sand River Catchment, South Africa.
