- The tidal current in the radial sandbanks area apparently has directional to - and - fro movement , which can be observed not only from tidal ellipses , but also from water particle traces . the calculated distribution of tidal velocity in this area shows that the average velocity is around 0 . 6 to 1 . 0 m / s
平面潮流椭圆、水质点迹线、潮流流速特征研究表明，辐射状沙脊群海域潮流具有明显的定向往复流形式，平均潮流流速一般为0 . 6 1 . 0m s ，满足形成潮流沙脊的水动力条件。 - The geomorphological instantaneous unit hydrograph ( giuh ) is viewed as the frequency distribution of the times of arrival of individual water deoplets at the catchment outlet . the travel path , for a typical hillslope cell . consists of a hillslope fraction , corresponding to overland flow and a stream fraction , corresponding to concentrated channeled flow . to obtain the time of travel , velocities must be defined . hillslope and stream velocities vary with location and must be strongly correlated with slope , and therefore a spatial distribution of velocities and hence of travel times could be obtained . the present methods of giuh neglect any time delays associated with overland flow pathways
地貌单位线被看作是流域上各水质点在弱相互作用下，到达流域出口汇流时间的频率分布。对于一个典型的山坡型网格单元，汇流路径由两部分组成，即坡地部分和河道部分，为了得到汇流时间，必须首先确定汇流速度。坡地和河道的汇流速度随着区域位置而变，并且必然与坡度有关，因此，可首先计算流速的空间分布，进而得到汇流时间的空间分布。 - Wave off into shallow waters , seabed by the friction effect change steep wave front , trough ice , water points trajectory showed reciprocating flow , but also to the shore into the flow speed usually return rate greater than offshore , the net result of sediment at the bottom to the shore handling , and was the shock waves on the shore with the water current - riviera online accumulation
外海波浪传入近岸浅水区，受到海底的摩擦作用，波锋变陡、波谷变缓，水质点运动轨迹呈现往复流动，而且向岸进流速度通常大于离岸回流速度，导致底部泥沙净向岸搬运，并被激岸浪的上冲水流带至海滨线上堆积。
