In this study, abstraction, desalination and recharge method and SEAWAT numerical model are used to investigate seawater intrusion repulsion in a hypothetical two-dimensional coastal aquifer to understand the relation of seawater intrusion with abstraction, desalination and recharge parameters (i.e. abstraction/recharge rate, wells distance and depth). Abstraction, desalination and recharge con...

Saltwater intrusion (SWI) is a type of pollution that adversely affects the quality groundwater in coastal aquifers. The Nile Delta aquifer (NDA) Egypt contains large amount freshwater. Increasing abstraction from and sea level rise have led to an increase SWI, which has reached up 100 km inland. Therefore, practical measures are required prevent further SWI. This study aims identify optimal we...

We optimize groundwater management in the presence of marine consequences of submarine groundwater discharge (SGD). Concern for marine biota increases the optimal steady-state head level of the aquifer. The model is discussed in general terms for any coastal groundwater resource where SGD has a positive impact on valuable near-shore resources. Our application focuses of the Kona Coast of Hawai’...

The Algarve region of Portugal is experiencing severe water scarcity with existing supplies insufficient to meet demand, limited resilience drought. Managed aquifer recharge (MAR) can provide intermediate storage and bridge the gap between availability success depending on available capacity accept store water. We present results a regional study quantifying both these aspects estimate potentia...

Groundwater constitutes 99% of all liquid freshwater globally that is available for human use. levels in the Nairobi aquifer system (NAS) have been declining over time because excessive abstraction fueled by increased water demand. This has cost pumping and drilling boreholes, which unsustainable. The objective this study to determine effect recharge on groundwater using a more realistic approa...

The effect of future climate scenarios on surface and groundwater resources was simulated using a modeling approach for an artificial recharge area in arid southern Iran. Future climate data for the periods of 2010–2030 and 2030–2050 were acquired from the Canadian Global Coupled Model (CGCM 3.1) for scenarios A1B, A2, and B1. These scenarios were adapted to the studied region using the delta-c...

In this work, the electrodes of a microbial desalination cell (MDC) are investigated as the positive and negative electrodes of an internal supercapacitor. The resulting system has been named a supercapacitive microbial desalination cell (SC-MDC). The electrodes are self-polarized by the red-ox reactions and therefore the anode acts as a negative electrode and the cathode as a positive electrod...

Groundwater depletion is the natural consequence of withdrawing water from an aquifer at a higher rate than recharge. If groundwater abstraction exceeds recharge for extensive areas and long time, overexploitation or persistent can occur [...].

This study applies a production function approach to value the groundwater recharge function of the Hadejia-Nguru wetlands in northern Nigeria. The groundwater recharge function supports dry season agricultural production which is dependent on groundwater abstraction for irrigation. Using survey data this paper first carries out an economic valuation of agricultural production, per hectare of i...

Surplus water from seawater desalination plants along the Israeli Coast can be injected underground for seasonal storage. Two pilot projects were established to simulate the movement of air bubbles and changes in the well hydraulic parameters during pumping and recharging. The study showed that it is impossible to remove the smaller air bubbles (dissolved air) that are created during the inject...
