The present study discusses one-dimensional modeling of the coal ash spill into the Dan River in February 2, 2014, using CCHE1D model. The simulations involved unsteady flow hydrodynamics, unsteady non-equilibrium transport of bed material and coal ash in multiple size classes. Discharges of coal ash transport and percentages of coal ash deposited in the mixing layer are presented. The paper presents the investigation of the sensitivity of model results to the rise time and fall time of the triangular hydrographs of pond water and coal ash discharges into the Dan River, the number of size classes used for modeling bed material and coal ash, the mixing layer thicknesses and the nonequilibrium adaptation length.
