River basins have long been attracting human settlement and development, promising water and fertile lands (Newson 1992). The Bot River Catchment on the southern coast of South Africa is no exception. However, much of the development in this catchment has not been controlled and its land and water resources are being abused. This is affecting the water quality and quantity of the river system and estuary at an alarming rate. In this thesis, the ‘reference’ land cover in the Bot River Catchment is recreated. This term is used to describe “the hydrological state of the catchment as it was when completely covered in natural vegetation, thus before it was impacted by humans” (Jacobs & Bruwer 2002:12). A rainfall-runoff model is employed to investigate the effects of various land covers on the catchment’s runoff quantity, by comparing the simulation results of the catchment’s reference and current state. The results of the model point to a large reduction in runoff since the reference state of the catchment. As the rainfall-runoff model applied did not allow for modelling of the annual agriculture that dominates the catchment, the runoff reduction was attributed to the smaller areas of perennial agriculture, forestry and alien vegetation infestation. The simulation results confirmed the threat of current land use practices on the environmental integrity of the Bot River Catchment. A transition to agricultural practices that are more suited to the climate is suggested and the eradication of alien vegetation should be seen as a priority. Most importantly, a holistic approach should be taken towards the management of the Bot River Catchment. The altered hydrodynamic regime of the Bot River Estuary is symptomatic of misuse of the entire catchment. As ongoing demographic and land use pressures create a new generation of water management problems (Department of Water Affairs & Forestry 1993), a deeper understanding of the relationships between the different components in the Bot River Catchment becomes increasingly urgent.
