地下水位变化 meaning in English
changes of water table
Examples
- A study on the variation and forecasting models of groundwater level and draining waterlogging in cultivated soil layers in the jianghuai valley
江淮流域地下水位变化规律及预报模型与耕作层排渍模型研究 - The deformation of slope caused by change of ground water level was investigated by adopting a fully coupled procedure and the state - dependent dilatant sand model
本文采用完全耦合有效应力分析程序和与状态相关的剪胀性砂土模型模拟斜坡因地下水位变化而发生的变形。 - 7 topography and land use are main factors affecting the change of groundwater table , then influencing the redistribution of soil moisture and salinity . soil secondary salinization can be considered as the main factors that influence the stability of new oasis in alluvial plain
7 、地形和土地利用是影响阜康荒漠绿洲地下水位变化的关键因素，而地下水位的连续变化又影响了土壤水盐在空间上的分布。 - Groundwater level prediction is also a very important field in groundwater environment prediction . land subsidence , encroachment of sea water and deterioration of water quality and so on by artificial development have relation to sustained drop of groundwater level . after groundwater level change mechanism was analyzed , the establishment method of groundwater level prediction regression analysis model was explored . and the groundwater level development trend of some planning region with the model was predicted according to its change characters of groundwater level , wath ' s more , the prediction results was analyzed
地下水位的预测也是地下水环境预测的重要内容，地下水在开采过程中所产生的地面沉陷、海水入侵、水质恶化等现象均与地下水位持续下降有关，本文在对地下水位变化机理分析的基础上，探讨了地下水水位预测回归分析模型的建立方法，并针对某规划区地下水位变化的特点，应用该模型对该规划区地下水位发展趋势进行了预测，并对预测结果进行了分析。 - The alteration procedure of the underground water level is simulated under drizzle and storm rainfall conditions respectively adopting the coupling fem analysis program of surface flow and subsurface flow . the numerical simulation of the underground water level shows that the drain ditch installed over the slope does not have an notable effect on the underground water level
利用降雨条件下地表水入渗和产流耦合的计算程序，模拟了小降雨强度和大雨强度对地下水位变化的影响，并用数值计算给出了地表排水沟对地下水变化的影响不是很显著的结论。
