Provenance and depositional environments of early cretaceous sediments in the Bredasdorp Sub-basin, offshore South Africa: an integrated approach
(University of the Western Cape, 2020)Southern offshore basins of South Africa are well known as potential provinces of hydrocarbon exploration and production. The complex nature of the Bredasdorp sub-basin’s syn-rift architecture (transform fault system) can ... -
Foraminiferal biostratigraphic studies from Mesozoic succession of selected wells from the Orange Basin, western offshore, South Africa
(University of the Western Cape, 2020)Located on the western offshore on the Atlantic Ocean margin of Southern Africa, the Orange Basin is the youngest and largest of the South Africa’s seven sedimentary basins. This passive margin basin in known for its ... -
A critical assessment of the social and economic aspects of environmental impact of assessment in South Africa.
(University of the Western Cape, 2002)MAGISTER SCIENTlAE IN THE FACULTY OF NATURAL SCIENCES OF THE UNIVERSITY OF THE WESTERN CAPE. This thesis focuses on Environmental Impact Assessments (EIA's) as prepared in the Western Cape Province. The thesis attempts ... -
The impacts of channelisation on the geomorphology and ecology of the Kuils River, Western Cape, South Africa
(University of Western Cape, 2003)Urbanisation and storm water input in the Kuils River catchment changed the flow of the river from ephemeral to perennial. This led to flooding problems in the Kuilsrivier central business district. The river was channelised ... -
Geomorphic analysis of river character and behaviour in three semi-arid, mountainous catchments in the Eastern Cape, South Africa
(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 ... -
The petrogenesis of the intermediate to mafic rocks of the yzerfontein subsuite, and their relationship to-, and paragenesis of hydrothermal veining, cape granite suite, saldania belt, south africa
(University of Western Cape, 2020)The 535 Ma post-orogenic Yzerfontein Pluton is a composite pluton that comprises rocks of mafic, intermediate and felsic compositions belonging to the shoshonitic series. The Yzerfontein Pluton forms part of the Cape Granite ... -
Understanding Striga occurrence and risk under changing climatic conditions across different agroecological farming systems at local and regional scales122
(University of Western Cape, 2020)The invasion by Striga in most cereal crop fields in Africa has posed an acute threat to food security and socioeconomic integrity. Consequently, numerous technological and research developments have been made to minimize ... -
Spatial modelling of invasive species distribution in water-limited environments using remotely sensed data and climatic scenarios in the Heuningnes catchment, South Africa
(University of Western Cape, 2020)The occurrence and spread of Invasive Alien Plants (IAPs) is a threat to global water resources and natural ecosystems due to high water use rates. With the current climate change projections and their ability to survive ... -
Regional groundwater monitoring in the Olifants-doom water management area
(University of Western Cape, 2006)The aim of this investigation was to provide a framework or strategy for prioritising and implementing regional groundwater monitoring in the OlifantsDoom Water Management (WMA) area. Regional groundwater monitoring is ... -
The influence of clay diagenesis on the petrophysical properties of sandstone reservoirs in the Pletmos Basin Offshore South Africa
(University of Western Cape, 2020)Pletmos Basin is a Mesozoic half graben located in the southern part of South Africa and has undergone numerous tectonic changes which involve alteration of structure and reworking of sediments. Clay diagenesis has become ... -
Foraminiferal biostratigraphy and depositional environment of the early cretaceous drilled succession in Durban basin, east coast, South Africa
(South African Journal of Higher Education, 2020)Durban Basin located on the eastern coast of South Africa has been a focus of interest for Petroleum Exploration for the last few decades. Only four exploratory wells have been drilled in this offshore basin without success. ... -
Using hydrogeochemistry and geophysical techniques to determine the extent of connectivity between Langerban road and Elandsfontein aquifer system, West Coast, South Africa
(University of Western Cape, 2020)The heterogeneity in groundwater systems suggest that not all aquifers are connected in groundwater systems. This study is about the interaction between aquifers within groundwater system. Langebaan Road and Elandsfontein ... -
Measurement and modelling of catchment erosion dynamics under different land cover types, Jonkershoek Catchment, Western Cape
(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 ... -

Effects of clay minerals on the petrophysical properties of sandstone reservoirs from the Offshore Pletmos Basin, South Africa
(University of the Western Cape, 2019)With the latest advancements in the Pletmos Basin it is imperative to understand and study how sandstone reservoirs are affected by clay minerals. Clay minerals are an influential component in sandstone reservoirs worldwide ... -
Using citizen science in monitoring groundwater levels to improve local groundwater governance, West coast, South Africa
(University of the Western Cape, 2019)Monitoring of groundwater levels provides a basis for assessing the availability of water in aquifers, thereby informing the decisions on abstraction and uses of such water for various purposes. It provides an understanding ... -
Characterizing water quality of rivers and underlying aquifers in the Nuwejaars Catchment, South Africa
