Short summary
Soil erosion threatens global food security, yet modeling soil conservation remains challenging. We evaluated WaTEM/SEDEM (Water and Tillage Erosion Model/Sediment Delivery Model) in six highly instrumented micro-scale watersheds optimised for soil conservation using a GLUE (Generalized Likelihood Uncertainty Estimation) framework. The model captured the magnitude of very low sediment yields but showed limited accuracy for annual steps. However, it performed well over eight-year timeframes and larger spatial scales, demonstrating its suitability for strategic, long-term soil conservation planning.
