冲蚀速率 meaning in Chinese

erosion rate

Through analysis , we conclude that washing action of wave and flow is main power of evolvement of region of interest landform , structure lead to the fact that water area around shallow structure in cheng dao sea field has an increase about 0 . 3m / a through actual measurement , water depth increase rate around foundation is 0 . 25m / a , slope gradient of side slope averagely has a decrease of 5 % o a year , however marine hydropower wash rate through compute is 0 . 2m / a on underwater bottom , the wash rate on structure foundation is 0 . 35m / a
分析认为，浪流的冲刷作用是研究区水深地形演化的主要动力，构筑物的存在，使埕岛海域浅水区人工构筑物周边水域实测年水深增加幅度约0 . 3m a ，地基附近水深增加速率0 . 25m a ，边坡坡度平均每年以5减缓，而计算得出的海洋水动力冲蚀速率在水下底坡为0 . 2m a ，在构筑物地基冲蚀速率达0 . 35m a 。
