What is it?
Extensive information on the water resources of South Africa, Lesotho and Swaziland in the form of monitoring data, GIS maps, water resource models, spreadsheets and tools.
- GIS maps for rainfall, evaporation, streamflow, groundwater
- Land use and water use data
- WRSM/Pitman rainfall-runoff model datasets
- Study began in 2012 and completed in 2016
Why is it Important?
The data and tools on the website enable water resource practitioners to investigate, analyse and plan their water resources studies.
How can it be accessed and used?
There are a number of water resource sections such as:
- GIS Maps of rainfall, evaporation, runoff, land use, geology, soils, sediment, vegetation, EWR, water quality streamflow, groundwater
- WRSM/ Pitman rainfall-runoff model datasets
- Streamflow data in rivers and dams
- Catchment rainfall data
- Naturalised flow datafiles
- Water quality data
- Land use/ water use data for every quaternary catchment
- Reservoir records and dam balances
In each of these sections you will be able to download spreadsheets or shapefiles (SHP) directly, after registering as a user on the system.
For additional water data see Department of Water and Sanitation sites (such as the Water Quality Data Exploration Tool or GIS data page) or the hydrographical data layers in the NGI topographical datasets via SASDI (such as for the Northern Cape).
