Abstract

The Yellow River Delta supports the ecological function as a typical estuarine foreshore wetland. The wetland area is changing greatly every year because of sediment deposition and erosion, which influences the wetland function tremendously. Application of environmental fluid dynamics code (EFDC) to the Yellow River Delta is on the basis of the mobile bed dynamic model and wetting-drying process. Careful calibration is carried out for the numerical model which is set up for the Yellow River Delta, the sediment transport process of the model is compatible to the Yellow River situation. The simulated bed elevation by considering the sediment deposition in the Mouth is particularly focused on, the numerical results are in agreement with the measured bed morphology within 1992–2000. Simulation in this paper indicates that most of the sediment deposited just out of the Mouth which makes the mouth move forward into the sea 2.5 km per year. This paper presents good results in simulation of varying sediment deposition and provides further methods to predict the future morphology and area of the Yellow River Delta.
