Drainage of a horizontal Boussinesq aquifer with a power law hydraulic conductivity profile
[1] Solutions to the Boussinesq equation describing drainage into a fully penetrating channel have been used for aquifer characterization. Two analytical solutions exist for earlyand late-time drainage from a saturated, homogeneous, and horizontal aquifer following instantaneous drawdown. The solutions for discharge Q can be expressed as dQ/dt = aQ, where a is constant and b takes on the value ...
متن کاملGroundwater flow to a horizontal or slanted well in an unconfined aquifer
[1] New semianalytical solutions for evaluation of the drawdown near horizontal and slanted wells with finite length screens in unconfined aquifers are presented. These fully three-dimensional solutions consider instantaneous drainage or delayed yield and aquifer anisotropy. As a basis, solution for the drawdown created by a point source in a uniform anisotropic unconfined aquifer is derived in...
متن کاملPumping-induced drawdown and stream depletion in a leaky aquifer system.
The impact of ground water pumping on nearby streams is often estimated using analytic models of the interconnected stream-aquifer system. A common assumption of these models is that the pumped aquifer is underlain by an impermeable formation. A new semianalytic solution for drawdown and stream depletion has been developed that does not require this assumption. This solution shows that pumping-...
متن کاملPredicting water level drawdown and assessment of land subsidence in Damghan aquifer by combining GMS and GEP models
It is over two decades that groundwater flow models are routinely implemented for better management of groundwater resources.Modeling groundwater flow with the help of the ground water modeling system (GMS) in the Damghan plain aquifer in northern Iran,which experiences declining levels and numerous environmental hazards, has demonstrated that, (a) in the worst case scenario theaquifer will fac...
متن کاملa comparison of linguistic and pragmatic knowledge: a case of iranian learners of english
در این تحقیق دانش زبانشناسی و کاربردشناسی زبان آموزان ایرانی در سطح بالای متوسط مقایسه شد. 50 دانش آموز با سابقه آموزشی مشابه از شش آموزشگاه زبان مختلف در دو آزمون دانش زبانشناسی و آزمون دانش گفتار شناسی زبان انگلیسی شرکت کردند که سوالات هر دو تست توسط محقق تهیه شده بود. همچنین در این تحقیق کارایی کتابهای آموزشی زبان در فراهم آوردن درون داد کافی برای زبان آموزان ایرانی به عنوان هدف جانبی تحقیق ...
