Recharge areas and geochemical evolution of groundwater in an alluvial aquifer system in the Sultanate of Oman

A regional hydrogeochemical model was developed to evaluate the geochemical evolution of different groundwaters in an alluvial aquifer system in the Interior of Oman. In combination with environmental isotopes the model is able to extract qualitative and quantitative information about recharge, groundwater flow paths and hydraulic connections between different aquifers. The main source of water ...

Uncertainty and urban water recharge for managing groundwater availability using decision support

Quantifying groundwater availability depends upon sound methods and the use of integrated models. To determine availability or sustainable yield, the influence of scientific uncertainty from key sources, such as anthropogenic recharge, must be considered. This study evaluates uncertainty in recharge interpretations on the modeled available water balance for an urban case in Texas, USA. Analyses ...

Modeling the groundwater recharge in karst aquifers by using a reservoir model

The estimation of the groundwater recharge in a karstic system becomes an important challenge due to the great hydrodynamic variability in both time and space. This paper proposes a two reservoir conceptual model to simulate inflow into both the conduit system and the fissure network system based on the analysis of the spring hydrograph. The structure of the model and the governing equations are ...

Investigation of introducing water from an artificial recharge plant to an existing groundwater distribution system

ABSTRACTThe consequences of mixing water from the Arrenaes Artificial Recharge (AR) trial plant with groundwater from existing well fields have been investigated. The potential problems of interest are bacterial regrowth, precipitation of iron, and corrosion in the raw water distribution system. The AR trial plant is located on the Arrenaes peninsula on Zealand, Denmark. A large-scale production ...

A GIS-based methodology to delineate aquifer recharge areas

A GIS-based methodology to delineate risk areas for contamination of groundwater resources is presented by identifying recharge conditions to the aquifer. Identifying the recharge areas is based upon surface and subsurface geologic conditions that may control the risk of potential oil spill contaminants into the aquifer. This study uses the Chicot aquifer system in southwest Louisiana as a pilot ...

Relevance of hydrological parameters in artificial recharge sites selection and assessment in a granitic aquifer

Due to increasing demand of groundwater and indiscriminant pumping, groundwater levels have been declined beyond economic levels and the natural recharge is not enough. Thus enhancing recharge to the groundwater system through artificial means has been evident. Depending on the situation, a variety of methods have been in practice but assessing their efficacy as well as optimal site selection has ...

Uncertainty Analysis of Mound Monitoring for Recharged Water from Surface Spreading Basins

This study has conceptually reviewed issues related to implementation of a groundwater mound monitoring well (GMMW) for monitoring recharged water from a surface spreading basin with emphasis on uncertain hydrogeological conditions. For this, we selected a recharge site in the City of Mesa, Arizona, that is characterized with near surface clay lenses of low permeability. A geostatistical ...

Optimal location of artificial recharge of treated wastewater using fuzzy logic approach

Increasing water demands in light of limited water resources have intensified exploitation and drawdown of groundwater. On the other hand, rising water demand has accelerated wastewater production. Therefore, urban wastewater management via artificial recharge may play a significant role in aquifer management. While site selection for artificial recharge projects is a major challenge, fuzzy ...

Managed aquifer recharge: rediscovering nature as a leading edge technology

Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe in recent years as an efficient means of recycling stormwater or treated sewage effluent for non-potable and indirect potable reuse in urban and rural areas. Yet aquifers have been relied on knowingly for water storage and unwittingly for water treatment for millennia. Hence if ‘leading edge’ is defined as ...

In Search of Ideal Groundwater Treatment

As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

Groundwater banking: opportunities and management challenges

Groundwater banking is the use of aquifers to store water to balance seasonal or longer-term variations in supply and demand. The large storage capacity provided by aquifers can be a valuable tool for conjunctive use of surface water and groundwater as well as other elements of integrated water resources management. Successful groundwater banking requires favorable hydrogeological conditions to ...

Groundwater levels under climate change in the Gnangara system, Western Australia

The Gnangara system is the main source of freshwater for Perth, Western Australia. However, aquifers in the region are under severe stress due to a drying climate, intensive pumping and changes in land use. The aim of this study is to apply the mean rainfall cumulative deviation and Mann-Kendall analyses at 77 monitoring bores to investigate the response of the water table to key recharge ...

Generalization and formalization of the US EPA procedure for design of treated wastewater aquifer recharge basins: II. Retrofit of Souhil Wadi (Nabeul, Tunisia) pilot plant

The ‘Cap Bon’ peninsula in Tunisia suffers from intensive tourist activities, high demographic increase and industrial development. As groundwater had been for a long time the main water source, aquifers had been subject to a severe depletion and seawater intrusion. Despite the measures taken prohibiting new drillings and water carrying by the construction of a waterway linking the ...

$Evaluating groundwater sustainability for fractured crystalline bedrock$

Evaluating groundwater sustainability for fractured crystalline bedrock

Water sustainability is an important concern for communities that rely on groundwater in fractured rock; yet the complexity of the fracture system and the unknown rate of recharge make quantifying groundwater availability difficult, if not impossible, using conventional water balance calculations. This study provides a new approach for estimating groundwater sustainability in fractured rock that ...

Monitoring groundwater resources for Municipalities - Case Study

Background The City of Tucson is located in the Sonoran Desert in southwest United States (U.S.), approximately 100 km north of the Mexico-U.S. border. Tucson Water operates more than 215 groundwater wells, covering more than 300 square miles, providing more than 37 billion gallons (140 million m3) of potable water to its 730,000 inhabitants each year. The region receives only 12 inches of ...

Groundwater resources of a multi-layered aquiferous system in arid area: Data analysis and water budgeting

The Maknassy basin in central Tunisia receives insignificant precipitation (207 mm/y), but the hydrological system retain very small quantities of water due to the steep topography and surface water resource partially mobilised witch is evacuated toward the basin outlet. However, the Maknassy plain support agriculture based on ground water ...
