چکیده

آگاهی از مقادیر و تغییرات پارامترهای هیدرولوژیکی آبخوان­ها در راستای مدیریت پایدار و حفاظت از منابع آب های زیرزمینی بسیار مهم و حیاتی است. از جمله پارامترهای هیدرولوژیکی آبخوان نشتی در جریان آب های زیرزمینی، ضریب قابلیت انتقال و نشت ویژه می­­­باشد. نوآوری این تحقیق بررسی تاثیر تغییرات این پارامترها بر روی جریان دائمی آب زیرزمینی آبخوان های نشتی محدود و نامحدود با استفاده از روابط دقیق و جدید ارائه شده در این پژوهش می­باشد. در این تحقیق آبخوان های نشتی نامحدود و محدود در حالت جریان دائمی آب های زیرزمینی مورد بررسی قرار گرفتند و با استفاده از یک روش تحلیلی، روابطی جدید و دقیق برای محاسبه مقدار افت سطح پیزومتریک در هر کدام از آبخوان ها به دست آمده است. همچنین با استفاده از این روابط آنالیز حساسیت ضریب قابلیت انتقال و نشت ویژه آبخوان ها انجام شده است.

چکیده [English]

Knowing the values and changes of hydrological parameters of aquifers for sustainable management and conservation of groundwater resources is very important and crucial. Among the hydrological parameters of leakage aquifer in groundwater flow are transmissibility coefficient and specific leakage. The innovation of this research is to study the effect of changes in these parameters on the steady flow of groundwater of finite and infinite leakage aquifers using the new and accurate selotions provided in this investigation. In this research, infinite and finite leakage aquifers in steady state of groundwater flow were studied and with using a new analytical method, new and exact solutions for calculating the drawdown in each of the aquifers were achieved. Also using these selotions, the sensitivity analysis of transmissibility coefficient and specific leakage of aquifers were done.
