A comparison of Remotely-Sensed Precipitation Estimates with observed data from rain Gauges in the Western Cape, South Africa
Maswanganye, Sagwati Eugene (University of the Western Cape, 2018)Precipitation data are critical for management of water resources. Precipitation can be measured through ground measurement by means of rain gauges and by remote sensing techniques. Rain gauges often give accurate measurements, ... -
Effects of catchment management on physical river condition, chemistry, hydrogeomorphology and ecosystem service provision in small coastal rivers of the Western Cape
Petersen, Chantel R. (University of the Western Cape, 2019)River systems are by nature complex and dynamic systems, which vary in structure and therefore function, and are closely connected to their landscapes. The primary aim of this thesis was to develop a systems operational ... -
Environmental modelling of wetland distribution in the Western Cape, South Africa: A climate change perspective
Mohanlal, Shanice (University of Western Cape, 2021)Wetlands have been recognised as one of the most intrinsically valuable and threatened ecosystems in the world. Global estimates indicate that wetlands are being lost or transformed at a rapid rate, exacerbated by projected ... -
Geomorphic analysis of river character and behaviour in three semi-arid, mountainous catchments in the Eastern Cape, South Africa
Sekese, Siviwe Pamela (University of Western Cape, 2019)The analysis of what controls why rivers are the way they are, and how and why they change is crucial in predicting river dynamics and deriving classification systems that can assist management. A variety of factors control ... -
Identification and prioritization of areas for riparian buffer restoration in the Sout River catchment, Overberg District, Western Cape
Manchidi, Tshireletjo (University of the Western Cape, 2023)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 ... -
Investigating associations between fluvial style and the characteristics and distribution of geomorphic units in non-perennial rivers
Grootboom, Curtis Renatius (University of the Western Cape, 2019)Although non-perennial rivers are the most dominant river type in arid and semi-arid areas, far outnumbering perennial rivers, recent reviews have shown that the knowledge base supporting non-perennial river research is ... -
Measurement and modelling of catchment erosion dynamics under different land cover types, Jonkershoek Catchment, Western Cape
Abrahams, Ebrahiem (University of the Western Cape, 2020)Several attempts have been made to assess the impact of post-fire soil erosion; however, erosion occurs as a result of the complex interplay between many factors, such as climate, land cover, soil and topography, making ... -
Understanding spatial patterns of dispersal and deposition of fine sediment and adsorbed phosphates in the Wiesdrift Wetland on the Nuwejaars River, Cape Agulhas
Jagganath, Tashveera (University of the Western Cape, 2021)River catchments in agricultural areas are strongly influenced by runoff from cultivated or grazed fields, and nutrient loading of these fields can result in large quantities of nitrates and phosphates being transported ...
