Identification and prioritization of areas for riparian buffer restoration in the Sout River catchment, Overberg District, Western Cape

Abstract

River catchments in areas dominated by agricultural activities are prone to contamination by nutrient-rich sediments whereby phosphorus is most concern. Phosphorus binds to fine sediments and gets transported to the rivers through surface runoff. Elevated levels of phosphorus in watercourse can compromise their water quality. One of the major consequences of high concentrations of phosphorus in watercourses is eutrophication which has detrimental effects on biota. Therefore, measures need to be put in place to protect water resources and prevent further water quality degradation.
