This study focuses on the influence of dam reservoir to cause excessive sediment disaster due to anomalous weather conditions by global warming. First, a sediment hazard probability model was developed and interpreted with observed sediment deposition records. Sediment yield was estimated for various return period and 5 year return period was found to be the best matched with the observed records. More over, it was observed that sediment production varies with particular land use in the region. Result of this study conform that the sediment hazard probability model is a much better tool to predict macroscale sediment storage in dam reservoirs.
