drastic model has been used to map groundwater vulnerability to pollution in many areas. since this method is used in different places without any changes, it cannot consider the effects of pollution type and characteristics. therefore, the method needs to be calibrated and corrected for a specific aquifer and pollution. in the present research, the rates of drastic parameters have been correct...
In this study, after simulating 5 years of saltwater intrusion with SEAWAT package in Astaneh–Kouchesfahan coastal aquifer, Iran, 19 strategies, including managerial, structural, and combined were investigated to reduce the intrusion. Since managerial solutions cause users’ dissatisfaction structural increase costs, two-player game theory was used identify most appropriate solution. According r...
Well designed monitoring networks are essential for the effective management of groundwater resources but the costs of monitoring well installations and sampling can prove prohibitive. The challenge is to obtain adequate water quality and quantity information with a minimum number of wells and sampling points, a task that can be approached objectively and effectively using numerical optimizatio...
The nomenclature for Kansas aquifers needs revision. Many of the names currently in use were derived in an ad hoc manner without the benefit of a consistent set of hydrogeologically based guidelines. Because nomenclature forms the basis of scientific discussion of hydrologic issues, names should be clearly defined and consistently applied in order to prevent erroneous or unintended hydrologic i...
The studied area located in south and south western Arak town and are the part of Sanadaj-Sirjan Zone. The plutonic rocks in Astaneh and Boroujerd areas are quartz diorite, granodiorite and monzogranite. In addition to plutonic rocks, subvolcanic rocks of rhyodacite composition are present in Astaneh area. In general, in these areass mineral assemblage is the same in different units. The common...
Wells screened across multiple aquifers can provide pathways for the movement of surprisingly large volumes of groundwater to confined aquifers used for public water supply (PWS). Using a simple numerical model, we examine the impact of several pumping scenarios on leakage from an unconfined aquifer to a confined aquifer and conclude that a single inactive multi-aquifer well can contribute near...
The Tamarack State Wildlife Area in eastern Colorado is being investigated as a possible managed recharge project to redirect flows in the South Platte River for water quantity management. Two primary surface water/groundwater interactions exist at Tamarack: (1) between the South Platte River and alluvial aquifer and (2) between backwater sloughs, or secondary river channels, and the alluvial a...
Background Nitrate is among major anions in drinking water. Therefore, it is crucial to investigate its concentration in water resources. Modeling is a management strategy to predict the behavior of nitrate in water resources. Objective The current study aimed to predict nitrate concentration in the aquifer of Qazvin plain, using Groundwater Modeling System (GMS). Methods The GMS7.1 software ...
Abstract—Adequate and reliable estimates of aquifer parameters are of utmost importance for proper management of vital groundwater resources. At present scenario, the ground water is polluted because of industrial waste disposed over the land and the contaminants are transported in the aquifer from one area to another area, which is depending on the characteristics of the aquifer and contaminan...
