Information on measured sediment load is important in the calibration of hydrologic models used in sediment yield prediction. The purpose of this study was to relate sediment load to discharge at a river section. An appropriate section was selected at the Lotanyanda river, Limpopo, South Africa. Depth integrated sediment samples were collected once a day on various dates at an appropriate interval and analyzed to determine the sediment concentration and turbidity. The water level and water temperature readings were also taken at the time of sediment sampling. Information obtained on sediment concentration and discharge was used to determine the sediment load on the dates when sampling was done commencing autumn through winter in the year 2016. Based on the values of measures of performance that included R 2 , NSE, RMSE, PBIAS and RSR, performance of predicted sediment concentration based on sediment rating curves was very good and could be used for predicting sediment load. The measures of performance, however varied from season to season. The relationship between sediment load and discharge varied from one season to another and the quality of fit (R 2 ) based on regression analysis differed from one season to another. Knowledge of sediment load discharge relationship can be used in sediment load prediction based on discharge information.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
