“射阳河口”属小型河口,在江苏海岸冲淤演化的空间格局中具有重要的位置。本文针对在河口修建挡潮闸和围垦这两种人类活动,设计了四种模拟方案:无闸、建闸(关闸)、开关闸(关闸、开闸在涨、落潮期交替)、围垦;分别进行模拟计算,并比较各方案中的流场、悬沙等特征。结果表明,与无闸时相比,建闸和围垦造成河道及河口区水位、流速、流向和悬沙浓度不同程度的变化。
“Sheyang estuary ” is a small estuary, in the Jiangsu coastal scour and siltation evolution spatial pattern has an important position. In this paper, four kinds of simulation schemes are designed for the construction of tidal flats and reclamation at the estuary. There are four kinds of simulation schemes: no gate, gate closing, gate opening and closing (gate closing and gate opening alternation), reclamation ; Respectively, to simulate the calculation, and compare the program flow field, suspended sediment and other characteristics. The results show that the water level, flow velocity, flow direction and suspended sediment concentration in river courses and estuaries are different from those in the absence of sluice.
