摘要：Potential areas for theuse of Small Reservoirs and Stone Bunds as agricultural water management interventions have been assessed using Weighted Overlay Analysis (WOA). The four key parameters that were combined to obtain the suitability levels of the interventions are runoff, soil type, land use/cover and slope. The results indicate high potential areas of 57.25% and 85.40% for small res ervoirs and Stone bunds respectively. Comparing the two interv entions in terms of slope suitability, the high potential areas for small reservoirs occurred on undulating slopes (0-8%) and that of the stone bunds on rolling slopes (8-16%). Luvisols and nitosols were identified by the model to be the soil types that support the use of small reservoirs and stone bunds in the high potential areas. A validation of the results revealed that 65.15% of existing small reservoirs in the study area were located in areas predicted by the model to be of high potential.
