A critical component in determining post-mining pit water quality is knowledge of groundwater fluxes, both as the pit fills and after steady state conditions have been reached. Simulations of the filling of an open pit in Crescent Valley, Nevada, were made to generate inputs for pit lake chemistry predictions. The simulations show that the water table recovery is most rapid immediately after pu...

Abstract The effects of changes in climate on aquifer storage and groundwater flow to rivers have been investigated using an idealized representation of the aquifer/river system. The generalized aquifer/river model can incorporate spatial variability in aquifer transmissivity and is applied with parameters characteristic of Chalk and Triassic sandstone aquifers in the United Kingdom, and is als...

In this paper, the Artificial Neural Network (ANN) approach is applied for forecasting groundwater level fluctuation in Aghili plain,southwest Iran. An optimal design is completed for the two hidden layers with four different algorithms: gradient descent withmomentum (GDM), levenberg marquardt (LM), resilient back propagation (RP), and scaled conjugate gradient (SCG). Rain,evaporation, relative...

Groundwater depletion poses a significant threat in arid and semi-arid areas where rivers are usually ephemeral and groundwater is the major source of water. The present study investigated whether an effective water resources management strategy, capable of minimizing evaporative water losses and groundwater depletion while providing water for expanded agricultural activities, can be achieved t...

Pavements consisting of water-permeable paving stone have a certain retention and storage capability for rainwater in the event of intense rain. Applied on a large surface, this results in a mitigation of flood events. Compared to an impermeable surface area, the surface flow rate decreases while groundwater regeneration increases. To date, the actual change in the third water balance parameter...

this paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from mighan playa aquifer. cluster analysis classified samples into four clusters(a, b, c and d) according to their dominant chemical composition: cluster a (dominant comp...

Groundwater is an important resource that can be used for various purposes. Various factors change the chemistry of GW, such as chemical composition aquifer well leaching human waste into groundwater. The study area a barren land covered by some sabkhas, in addition to agricultural fields. aims assess groundwater quality drinking purposes using Water Quality Index. chemically heterogeneous and ...

The Pantanal is a vast evaporation plain and sediment accumulation surface that floods annually. It is located in the Upper Paraguay River Basin, a major source of floodwaters to the Pantanal. The recent construction of a large dam in the upper reach of the Cuiabá River raises questions: What will be the dam influence on the flood area and duration? What will be the consequence for groundwater ...
