Abstract

Purpose of this study is to used the physicochemical parameters (DO, pH, NO3-, PO4 3-, TDS & TSI), water quality index of IRWQI and statistical methods to assess the pollution and spatial-temporal impact of LAND USE wastewaters on water quality in CHOGHAKHOR WETLAND in Chahar-Mahal Bakhtiari province, Iran. Sampling twelve stations were selected based on systematic non-random for the sampling and measurement. At first, index model of IRWQI was prepared in GIS environment based on average of surface and depth of qualitative parameters by interpolation functions (deterministic and geostatistical methods). Therefore, correlation coefficients of water quality index with stations proximity of LAND USE wastewaters based on buffering method was used for determination of LAND USE efficacy. Results, demonstrated that annual average of wetland IRWQI index (fairly good status of 70) with the pearson correlation coefficient of 0.78 and the parameters of PO4 3-, NO3-and TDS with partial correlation coefficients of -0.82, -0.64 and 0.62 respectively were caused by wastewaters pollution of farmland and residential area in the south and west half of wetland. Also results of spatial-temporal impact of LAND USE wastewaters using statistical and geostatistical methods showed that highest impact on water quality of CHOGHAKHOR WETLAND is created in spring and early autumn with correlation coefficients of 0.70 and 0.59, and lowest impact is reached in summer with correlation coefficient of less than 0.1.Maximum trophic and worst qualitative status is results for water surface temperature of 10.5-13.5oC in first half of autumn and spring with status of moderate to fairly good with values of 50 to 61 for this condition which is due to increased and best quality is in more than 19.5oC and less than 6oC in summer and first half of winter with good status of 70 to 82 for this condition which is due to decreased agricultural activities, floods, wastewaters of seasonal rainfalls and biological and chemical variations caused of temperature.
