摘要: Lake Urmia is known as one of the largest saltwater lakes on earth. In past decade, average water level this lake has decreased significantly and endangered its unique ecosystem. As such, surrounding groundwater are related together. Therefore, investigating changes in quality quantity occupies a very important status planning managing resources region. Most studies conducted to analyze time series trends have made use common non-parametric tests Mann–Kendall or Spearman’s Rho tests, which do not pay enough attention impact autocorrelation domain. Verily, coefficients may leave significant impacts trend qualitative quantitative resources. Regarding present study, parameters were analyzed using modified test with considering coefficients. addition, values slope estimated Theil–Sen estimator. The results indicated that was essential assessing trend. regarding well analysis temporal groundwater, it sodium adsorption ratio (SAR), NA %NA had ascending other decreasing thereof. spatial trend, found Na, EC, Ca, Mg, anions cations near City.
