introduction one of the most vulnerable water resources against contamination is ground water table. these resources are exposed to contamination in various forms. identifying and controlling contamination in these resources are more difficult and costly than surface waters. also because of the persistence of contamination in these resources, the best way to prevent their contamination is to id...

land use management policy and method are two important factors in usage of land by human. in this regard, evaluation of environmental capability would serve as a valuable basis for the best use practice of soil and water resources in addition to the reduction in environment consequences of the projects. in the correct study, the environmental capability of birjand plain, located in the south k...

Hydrological Processes. 2017;1–19. Abstract This study analyzes a long‐term regional compilation of water table response to climate variability based on 124 long‐term groundwater wells distributed across New England, USA, screened in a variety of geologic materials. The New England region of the USA is located in a humid‐temperature climate underlain by low‐storage‐fractured metamorphic and cry...

An analytical solution for the case of transient, pumping-induced drawdown in a nonuniform aquifer is presented. The nonuniform aquifer is conceptualized as a uniform matrix into which a disk of anomalous properties has been placed. The disk can be arbitrarily located with respect tothe pumping well. This solution can be used to develop considerable insight concerning the nature of drawdown i n...

The study area of Marand city is 45 ° 46 'east longitude and 38 ° 26' north latitude and is located in the northwest of East Azarbaijan province and 60 km northwest of Tabriz province. Unfortunately, in recent years, the development of countries, including Iran, has led to more exploitation and improper use of groundwater resources, which reduces these resources and does not control the amount ...
