Incorporating uncertainty in water resources simulation and assessment tools in South Africa
Expanded Title:The main objective of the project was to contribute to the incorporation of uncertainty assessments in water resource decision making in South Africa, and the main output was the development of a framework for uncertainty assessments in water resources availability analyses within South Africa. This framework has been based on international experience, the water resources analysis methods that are commonly applied within South Africa, the data constraints that exist within the country as well as the requirements for water resources management decision making. The framework has been supported by the development of some new approaches to applying existing hydrological models and illustrated by examples of their application. The project has identified the main sources of uncertainty and offers some recommendations on approaches to reduce the level of uncertainty. Some of these are achievable in the short-term through changes in technical practices (such as hydrological model parameter estimation), while others require closer engagement in the future between scientists, water resources engineers and policy makers at governmental level (such asimprovements in the national rainfall monitoring network).
