Webmudflow, flow of water that contains large amounts of suspended particles and silt. It has a higher density and viscosity than a streamflow and can deposit only the coarsest part of its load; this causes irreversible sediment entrainment. Its high viscosity will not allow it to flow as far as a water flow.
