| 1 | Sustainable Management of Runoff and Sediment Yield in a Rapidly Urbanizing Residential Area: A Case Study of Malete, Kwara State, Nigeria |
This study investigated the effects of the application of stone bunds and vegetative filter strip for sustainable management of runoff and sediment yield generated in Malete watershed, Kwara State, Nigeria. Soil Water Assessment Tool (SWAT) model interfaced with Geographical Information System (MapWindow GIS) was employed to simulate and predict the hydrological processes of the watershed into sub-basins which were further divided into Hydrological response units (HRUs). The model was used to evaluate the efficacy of the application of stone bund and vegetative filter strip in reducing storm water generated from the watershed. The outcome of the study showed that the total predicted surface runoff and sediment yield in the watershed were predicted as 131.53 million m 3 and 243.77 t/ha respectively. The maximum and minimum runoff predicted were 19.89 million m 3 and 17.76 million m 3 at sub-basins 13 and 7 respectively, and the average runoff predicted value was 16.44 million m 3 . Also, the maximum and minimum sediment yield in the watershed occurred at sub-basins 41 and 8 having predicted values of 46.40 t/ha and 11.26 t/ha respectively, and the average sediment yield predicted was 30.472 t/ha. The results revealed that the implementation of stone bunds reduced sediment yield by 93% while vegetative filter strip reduced it by 37%. In addition, the model could serve as a decision support tool for stakeholders and relevant local authorities to formulate policies and strategies in the management of runoff and sediment yield generation in the study area. | 3.
