河水涨落 meaning in English

river breathing
river stage fluctuation

Using ansys as analysis tool , and the influence of river water fluctuating on geoelectric observation data in different distance from riverway to geoelectric monitoring observe station is numerically simulated , and the relationship between error of observation data and distance from riverway to the stations is summarized
摘要利用ansys作为分析平台数值模拟了观测系统距河道不同距离情况下，由河水涨落引起的浅层局部电性非均匀性对地电观测数据的影响，总结了观测系统距河道远近与观测数据误差大小的关系。
