The rainfall-runoff-sediment yield process, which involves many mechanisms, is highly complicated and dynamic in nature. In the present study, an attempt has been made to develop dynamic sediment yield model, considering present day rainfall and runoff and past values of rainfall, runoff and sediment yield as the input variable, to estimate the sediment yield from a catchment on daily basis. The model was applied on Giridih watershed, a sub-catchment of Barakar river basin, Jharkhand, comprising an area of 731.02 km², to test its applicability and capacity to estimate and generate daily sediment yield data for the catchment. The estimated and generated values of sediment yield by developed model were found to be in good agreement with the measured values.
