The availability of water resources in South Africa is shrinking in terms of quantity and quality due to increasing requirements and the vastly changing land uses.
This reality necessitates the close management of natural resources and specifically water resources in a holistic manner and continuously monitoring from source to sea.
Therefore, the main objective of this study is to update the 2011 PES/EIS database that curated information for the main rivers in 1946 Quaternary Catchments in South Africa.
The study will focus largely on primary, secondary and quaternary catchments and should include the significant water resources in the proclaimed strategic water resource areas on sub-quaternary reaches (SQRs) level which include the associated lotic wetlands i.e. floodplainwetlands, channelled valley bottoms and estuaries situated in the SQR.
The wetlands database must be addressed in detail where e.g. seeps, unchanneled valley bottoms, pans and lakes that are not connected to a river.
A standardised approach for obtaining and reflecting the latter mentioned information will be provided, assessed and the approach agreed upon during the inception phase
