relative water depth meaning in English

相对水深

In the test of transmission coefficient property , semi - circle type , rectangle type , trapezoid type and concave type dyke are studied . research study is on the effect of relative water depth over the dyke to the transmission coefficient of the four different types dyke , and the comparison is done . finally , the experimental formula is given to the transmission coefficient , which are compared with the present formulae
在潜堤透射特性的研究中，选取半圆型、矩型、梯型和槽型潜堤作为研究对象，在分析各个影响因素对潜堤透射影响的基础上，选取最主要的影响因素，即相对堤顶水深作为研究的重点，分析研究了堤顶相对水深对四种结构型式潜堤透射系数的影响，比较分析了四种结构型式潜堤透射特性，在此基础上，总结了计算潜堤透射系数的经验公式，并与已存在的计算公式进行了对比，最后对潜堤的促淤效果进行了评估。
