چکیده

 دشت تویسرکان از دشت­های ممنوعه است که سطح آب زیرزمینی آن در 22 سال اخیر بیش از 11 متر افت داشته است. در این مطالعه روند کیفی آب زیرزمینی با استفاده از اطلاعات 15 حلقه چاهمشاهده­ای طی دوره آماری (1394-1384)، روند کمی آب زیرزمینی با استفاده از اطلاعات 17 چاه مشاهده­ای و هم­چنین روند تغییرات بارندگی با استفاده از اطلاعات 11 ایستگاه باران­سنجی طی دوره آماری (1393-1372) با آزمون ناپارامتری من­کندال بررسی شد. برای هر سری زمانی با استفاده از روش تخمین­گر سن، شیب‌خط روند محاسبه شد. پارامترهای کیفی مورد مطالعه شامل 13 پارامتر کیفی می­باشد که در هرسال، دو بار (دورهتر و دوره خشک) اندازه­گیری شده­اند.نتایج نشان داد  که دشت از لحاظ کیفی دچار افت شده و روند تغییرات کاهشی معنی­دار در سطح ایستابی، به میزان متوسط سالانه 53 سانتی­متر افت دارد. نتایج تحلیل بارش نشان‌دهنده آن است که بارش به‌طور متوسط، سالانه 75/3 میلی­متر کاهش دارد.

چکیده [English]

The groundwater level of Tuyserkan plain has dropped by more than 11 meters in the last 22 years. This study surveyed the trend of groundwater quality parameters in the study area using data from 15 observation wells from 2005 to 2016, the trend of groundwater quantity parameters using data from 17 observation wells, and also the trend of rainfall changes using 11 rain gauge stations data from 1993 to 2014 by non-parametric Mannkandal test. For each time series, the trend line slope was calculated using the Sen's slope method. The quality parameters included 13 parameters that were measured twice a year (i.e., during the wet and dry periods). Based on the results, the quality parameters of the plain decreased, and the trend of significant decreasing changes in the water table dropped by an average of 53 cm per year. Moreover, the results of precipitation analysis showed that the average annual precipitation decreased by 3.75 mm.
