Water Resource Management
The concept behind water resource management is to improve the effective and efficient use of existing and available water resources in all water sectors (urban and industrial). This section has many enlightening articles on the subject.< Back to Knowledge Center
The Use of Minewater to meet Future Urban Water Requirements in the Witbank Dam Catchment
The National Water Resources Strategy (NWRS) presents water balances for the water management areas (WMAs).
Surface,groundwater interaction- Using water balancing,hydraulic modeling and real-time monitoring to develop a truly
In drier parts of Southern Africa, water reservoir releases into riverbeds often lead to significant losses of flow volumes (river losses) and result in supply shortages for downstream water users.
Proposed Modelling Approach and Procedures for Water Availability
The DWAF Directorate: National Water Resource Planning has commissioned five studies on the Mhlathuze, Inkomati, Berg, Crocodile (West) and Olifants river systems, for the purpose of assessing the available water resources in support of the eminent process to license water use.
Practical experience with using the WQT irrigation block in the WRSM2000
The WQT salinity modelling system was developed in the late 1980s for the Department of Water Affairs and Forestry and has been used successfully throughout South Africa for Total Dissolved Solids (TDS) modelling.
Operating Rules for Dams with High Evaporation Losses
The purpose of this assessment was to determine general and drought curtailment rules for the major dams situated within the Great Marico River System.
Modelling Impacts of Dryland Sugarcane on Streamflows in a Water Stressed Catchment in KwaZulu-Natal
Recent studies have indicated that water allocated to users in the Mhlathuze River catchment exceeds the available yield of the system.
Management of Large Water Resource Systems
South Africa has one of the most complicated and integrated water resource systems in the world involving numerous interlinked river systems and major interbasin transfer schemes.
Lessons Learned from the Vaal River System Reconciliation Strategy Study
Reconciling the available water resources of the Vaal River System with the future expected water requirements of the system is an essential and continuous management activity of the Department of Water Affairs and Forestry (DWAF).
Hydraulic modelling in the water resources field- A practical application
In the latter part of the previous decade as well as the early part of this decade considerable time and effort have been spent developing a hydraulic model for the lower reaches of the Orange River (approximately 1 400 km from Vanderkloof Dam to the river mouth) during two Water Research Commission (WRC) managed studies.
Genetic Algorithms for Water Resource Assessments
The operating costs (in particular pumping costs) of the various water resource systems in South Africa amounts to hundreds of millions of Rands per year and much effort is invested by water resource planners to implement cost saving operating rules that do not jeopardize the long term assurance of supply.
Framework for Future Water Resource Analysis in South Africa
In the context of the challenges facing water resource management in South Africa and given the status of the prevailing analysis techniques, an evaluation of constraints and opportunities are presented to serve as background for a proposed framework for future water resource analysis in the country.
Development of Simplified Drought Operating Rules
The purpose of this development was to produce simplified curtailment curves that can be used to decide when and how severe curtailments need to be in periods of water shortage.
Development of an urban water requirement and return flow model
The Crocodile (West) River catchment, measuring approximately 29 300km² in extent, is a densely populated, substantially urbanised and industrialised catchment.
Component Based Analysis for Management of Leakage in Potable Water
Understanding and managing leakage in potable water distribution systems has always posed interesting and often difficult problems to the water supply authority.
Assessment of the water situation assessment model (wsam)
The Department of Water Affairs and Forestry (DWAF) developed the Water Situation Assessment Model (WSAM) as a macro-scale water resource planning tool.
Application on Groundwater-Surface water Interaction Modeling in the Schoonspruit Catchment
Under natural conditions approximately 50% of all the flow in the Schoonspruit catchment, comes from the Schoonspruit Eye, emphasizing the importance of the correct simulation of the eye flows.
Alternative Approach to the Lumping of Small Dams for the Purpose of Undertaking Water Resources Modelling
It is perceived that some uncertainty currently exists regarding the appropriate procedure that should be followed to lump small dams for the purpose of undertaking water resources modelling.
