Abstract: A model called ROTO was developed to estimate water and sediment yields on large basins (several thousand square miles). ROTO is a continuous model operating on a daily time step that accepts inputs from continuous time soil water balance models. Components for water and sediment movement in channels and reservoirs are included. ROTO uses a command structure to route and add flows down through the watershed. The model is currently being applied on large watersheds in Arizona and New Mexico.
