摘　　要：根据感潮河道水沙运动特点,建立了适用于有闸河道的一维泥沙、水质数学模型,可以对闸门不同运行方式下水流、泥沙、污染物运动进行模拟。并运用该模型,对永定新河蓄淡、蓄咸两种闸门利用方式下泥沙、污染物运动进行了研究,为闸门运行方式的选择提供了依据。According to water and sediment movement characteristics of the tidal river, an one-dimensional sediment and water quality model have been established, which can be used on the river controlled by a gate and to simulate the movement of water sediment and pollutant during different operation modes of gate. In new Yongding River, this model have been used to study the transportation of sediment and pollutant when using two operation modes which are the mode of storing fresh water and the mode of storing sea water, and a right operation mode of the gate may be get according to the study.
