Application of the Sediment Mathematical Modelling on Plannec Project of Lingdingyang Bay

摘要

Based on the combined hydraulic calculation for the eastern network region at the Pearl River estuary and several outlets to the Lingdingyang Bay, the sediment calculation modelling was introduced in the establishment of the sediment mathematical model for Lingdingyang Bay and the eastern region with one and two dimensional flow calculation. Model adjustment and verification were performed in conjunction with field data. The simulated results coincide well with measured data. In addition the model is applied to predict the shore-line planning scheme of Lingdingyang Bay. The theoretical criterion is provided for the shore line plan in the model. And a new mathematical simulated method is put out to research the planning engineering concerned with one-dimensional net rivers and two-dimensional estuary.
