Recently, special attention has been paid to artificial groundwater recharge in water resource management in arid and semi-arid regions. Water resources distribution in these regions is extremely uneven, both in spatial and temporal forms and groundwater is the only water resource and is a major constraint on economic and social development. Artificial groundwater recharge is considered an appr...

To demonstrate the capabilities of Geographic Information System (GIS) techniques and numerical modeling for groundwater resources development in arid areas, specifically for the demarcation of suitable sites for the artificial recharge of groundwater aquifers, a study was carried out in the Maknassy basin, which is located in Central Tunisia. Thematic maps were prepared using a Hydrogeological...

The paper aims at evaluating the effects of heavy groundwater withdrawal and artificial groundwater recharge of an exmining pond to the aquifer system of the Langat Basin through the three-dimensional (3D) numerical modeling. Many mining sites have been left behind from the massive mining exploitations in Malaysia during the England colonization era and from the last few decades. These sites ar...

A new method of evaluation of the response of a water table to artificial recharge is presented. The solution is formulated in the form of a simple numerical model. The model has several advantages over the traditional methods of mounding prediction. The effect of the unsaturated zone, which modifies the recharge rate as compared with the infiltration rate, is considered. Mounding is calculated...

The Latrobe Valley has an extensive monitoring network to measure the environmental impacts of mining and power generation operations. Regional groundwater and topographic survey data have been recorded for over 40 years. This data is used to calibrate mathematical models for the prediction of groundwater drawdown and subsidence. The concept of artificially recharging aquifers through re-inject...

Abstract The coupled MODFLOW-HYDRUS software package was used to produce a saturated-unsaturated flow model for a Flood Spreading System (FSS) and its associated aquifer. The study aim to improve simulations of near-surface hydrological processes, including temporal and spatial variation in groundwater recharge rates. The coupled model was built with average RMSE=1.1 and 1.3 for calibration ...

Artificial recharge improves several water quality parameters. Denitrification is a good example of water treatment process that could be achieved through artificial recharge. To improve the removal of nitrate and other emerging organic contaminants (EOCs) a reactive barrier at the bottom of an infiltration pond can be added. In the present study, the efficiency in removing nitrate of an artifi...
