Abstract

Groundwater and drainage-water sustainability is crucial to water management. Controlling the interaction between the groundwater and drain-water salinity at the watershed level has only been the topic of a limited number of studies. This study statistically compares salt concentration rate across time and four different flow regimes. We sampled water from 2014 to 2018. The study used R software to analyze water-quality parameters utilizing PCA and indices. Multiple water-quality indices were used to test irrigation water. A linear model with TDS as the response was fitted to the data. Another two-factor repeated-measurement covariate model was built. Water-quality indices suggest that measured water from varied flow regimes in the study area is suitable for irrigation. Based on the statistical models, Tukey's adjustment pairwise demonstrates considerable salinity variations between drain water and surface water. However, the main effect of the flow regime on TDS is significant. This indicates that the TDS value varies depending on the flow regime, not on time plus the interactions between these regimes. Keywords: Total dissolved solids (TDSs), Groundwater, ANCOVA, Flow condition, Tile drain, PCA
不同水流状态下的水质参数统计评估
地下水和排水的可持续性对水资源管理至关重要。在流域层面控制地下水和排泄水盐度之间的相互作用仅是少数研究的主题。本研究统计比较了不同时间和四种不同水流制度下的盐浓度率。我们采集了 2014 年至 2018 年的水样。研究使用 R 软件,利用 PCA 和指数分析水质参数。多种水质指数被用于测试灌溉水。一个以 TDS 为响应的线性模型被拟合到数据中。建立了另一个双因子重复测量协变量模型。水质指数表明,研究地区不同水流状态下测得的水适合用于灌溉。根据统计模型,Tukey 调整配对表明,排水与地表水之间存在相当大的盐度差异。然而,流态对 TDS 的主效应是显著的。这表明 TDS 值的变化取决于流态,而不是时间加上流态之间的相互作用。关键词总溶解固体(TDSs) 地下水 方差分析 流动条件 瓦片排水 PCA
