Deep porous reservoirs are subject to charge and discharge of fluids (oil, gas or water), either naturally or induced by human exploitation. This leads to a variation in pressure inside the reservoir and consequently to a deformation of the overlying material. The knowledge of the ground surface displacements allows inferring the fluid migrations and the hydromechanical properties in the porous...

Previously published field investigations and modeling studies have demonstrated the potential for sample bias associated with vertical wellbore flow in conventional monitoring wells constructed with long-screened intervals. This article builds on the existing body of literature by (1) demonstrating the utility of continuous (i.e., hourly measurements for ∼1 month) ambient wellbore flow monitor...

shohada (sepah) avenue in qazvin, a historic city, is a part of safavid era infrastructure of the city. it connects various important cites and poles like jame' mosque, imamzadeh hosein, dowlat-khaneh and the traditional bazaar complex to one another. this axis in khomartashi, in kabir jame' mosque - preservation and restoration of jame' mosque complex as principle core of the ci...

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...

In this study we propose a multi-source data approach for quantifying long-term flooding and aquifer recharge in ungauged ephemeral rivers. The methodology is applied to the Buffels River, at 9000 km2 the largest ephemeral river in Namaqualand (NW South Africa), a region with scarce stream flow records limiting research investigating hydrological response to global change. Daily discharge and a...

groundwater resources are the main source of water supply in many arid countries such as iran. because of uncontrolled increasing of the population, limitation of surface water resources and excessive extraction from aquifers, sharp drop in groundwater level in many plains such as khezel plain located in hamedan province was occurred. khezel plain is important because of strategic crop farming ...

River-recharged aquifers are developed for drinking water supplies in many parts of the world. Often, however, dissolved organic carbon (DOC) present in the infiltrating river water causes biogeochemical reactions to occur in the adjacent aquifer that create elevated Mn and Fe. Mn concentrations in groundwater from some of the production wells installed in the aquifer at Fredericton, New Brunsw...

River Bank Filtration is a water treatment technique that consists of bring out from river by pumping wells located in the nearby aquifer. It Aquifer Recharge which surface treated through aquifer medium. In present study an attempt made to understand impact on water, Jabalpur city Madhya Pradesh. The geological conditions, well types, cost saving coagulant and physical, chemical biological eff...
