For soil erosion modeling, determining sediment transport capacity (Tc) is essential because it plays a key role in sediment detachment, transport, and deposition research. This paper provides insights into the seasonal spatial distribution of sediment transport capacity, excess runoff depth in response to the distribution of precipitation, and land use at a watershed scale, using SCN Curve Number (CN) method, Remote Sensing (RS), and Geographic Information Systems (GIS). Spatial distribution in runoff production on hillslopes and sediment transport are explained. We integrated the effect of slope gradient in the curve number to model the landscape effect on sediment transport. The findings show that seasonal variation in sediment transport capacity is influenced by climate change. During June and October, the transport capacity is higher and coincides with channel areas in the Boubo watershed. Potential applications of this map may help the decision-maker to deal with problems associated with watershed development and management.
