Study on One Dimensional Mathematical Model for Unsteady Flow Sediment and Water Quality in Channel with a Sluice

Abstract:

Based on existing mathematical model for one-dimensional unsteady flow and non-uniform water-sediment, the inside boundary condition of sluice has been introduced to establish a mathematical model which is suitable for sediment and water quality in nontidal river channel with sluice, in combination with empirical model of local erosion-deposition and one-dimensional mathematical model for water quality. It can be used to simulate motion of water flow, sediment and pollutant under different operational modes of sluice in tidal reaches. In addition, a mathematical model calculation software for water-sediment and water quality has been developed on this basis after sluice has been built, which is also being used to study the influence of different application solution of sluice in Yongding New River on the motion of sediment and pollutant, so as to provide a basis for the selection of sluice operational modes.
