Abstract

The Free State province in South Africa is persistently affected by droughts leading to severe impacts on water bodies. In this study, remote sensing images from Landsat 8 were used to monitor the area covered with water and the density of vegetation around the Mockes dam area during the 2016 drought year in the Free State, South Africa. Short Wave InfraRed images (SWIR), together with Normalized Difference Water Index (NDWI) on the EOS (Earth Observation Satellite) hydrological models, were used to estimate the surface water in the Mockes dam over the four seasons of summer, autumn, winter and spring in 2016. The results indicated a decline in surface water in the Mockes dam between the seasons, as the year progressed and the drought intensified. Additional water was given to the Mockes dam from the Rustfontein dam in winter but the volumes also declined in spring. Throughout the summer, autumn and winter seasons, the vegetation surrounding the Mockes dam was severely stressed due to the unavailability of moisture from the soil.
