退水 meaning in Chinese
depletion
recession
su idingwater
subsiding water
Examples
- Study on the model of return water quality of irrigation in farmland
农田灌溉退水水量水质平衡模型研究 - Research of recession flow on the loess slope and its nitrogen pollution
黄土坡面退水及其氮污染试验研究 - Through the water quality analysis on the cod tp , tn in the irrigation water and drainage water in a model experimental field , the regulation and its influence on environmental water pollution by the drainage water was also studied
通过对萧山闻堰镇某二季晚稻试验田灌溉用水和农田排水的逐次记录和取样分析，研究了农田退水中cod 、 tp 、 tn的排放量和排放浓度变化，以及农田退水对本地水环境的影响。 - 4 . as for the three kinds of waterproof underlying surface , when rainfall intensity is strong , the rise process curve will steep in the process of discharge , and also speed of discharge to reach steady will quicker . but it produces little effects on duration of fall
4 .对于透水性差的下垫面，雨强越大，流量过程的涨水曲线越陡，且达到稳定流量的速度也更快，但对流量过程的退水历时影响不大。 - Thus , the next 1500 hours correspond to the base flow recession period . it is obvious that the aquifer with ampler water storage will produce larger subsurface runoff . from the above numerical simulations , one can see that the b - s model can reasonably simulate the subsurface runoff varia - tion in the two extreme conditions
而在持续了1500 h以后入渗突然都变为0对应着实际情况中径流的消退期,显然储水较多的潜水面的地下径流比较大,而随着退水的持续进行行,地下径流也越来越小
