Abstract

According to the nonlinear relationship among the components of AQUIFERs these systems are called as complex systems. Due to natural and artificial changes the estimating the degree of complexity of these systems is very important for groundwater quality and quantity assessments. In this study MULTI-SCALE ENTROPY (MSE) theory was applied to analyze long-term variation piezometers (1985-2014) in order to ascertain impacts of Saveh dam on the complexity of the Saveh AQUIFER plain located downstream of the dam. In this approach, unlike the sample entropy that calculates only the amount of entropy for a single scale factor, the MSE was used to assess the possible changes in the complexity of the AQUIFER in multi scale factors. The results showed that the complexity of the AQUIFER after the construction of Saveh dam decreased precipitously from the beginning of the AQUIFER plain to its middle line. An average of 31 percent increase can be seen in the entropy difference between the samples (complexity) in two periods (before and after the dam construction). The complexity properties alterations of the AQUIFER caused the destruction of natural systems AQUIFER and decrease the complexity of it. The comparison between proposed approach and Mann-Kendall method indicated the efficiency of MSE in evaluating the complexity of AQUIFER systems and detection of abnormal events in the groundwater table level time series. This study provided a reference for conservation of the AQUIFER natural environment and the assessment of impacts induced by big hydraulic structures on the groundwater system.
