Numerical Modeling of Recovery of Moisture from the Unsaturated Zone: A Feasibility Study.

Numerical modeling of the recovery of moisture by injecting warm air in the unsaturated zone in a 100 m × 100 m plot of agricultural land in Kuwait, a country located in an arid environment, was conducted to provide "proof of concept" of the technique. If technically and economically feasible, it will be a potential additional source of water that could be exploited for farming activities and other uses. The COMSOL software was used to develop the model and, based on the results of the scenario runs, the effects of different hydraulic and operational parameters, including that of well spacing, on moisture recovery were assessed.

A numerical modelling approach to investigate the fate of brine reject of farm scale desalination plants on groundwater aquifers in arid environments.

Farm-scale desalination units are gaining popularity for agricultural irrigation in arid countries, such as Kuwait to meet freshwater demands. However, less attention has been given to the management of environmentally hazardous brine reject water they produce. In this study we investigated the fate of brine water produced by the inland desalination units on the underlying aquifers using numerical modelling and field investigations.

Planning for a Multi-Well Artificial Recharge Field in Kuwait with the Help of Numerical Modeling.

Kuwait, an arid country, wants to have a reserve of water for emergency use and has planned to create an underground reserve of water through multi-well artificial recharge at Kabd area. Numerical modeling of different recharge-recovery scenarios was carried out to chalk out an optimum strategy for implementation of the project. These scenario runs suggested that apart from the aquifer parameters and the quality of the groundwater and the recharge water, the well spacing and well construction, orientation of the field with respect to the prevailing hydraulic gradient, and the injection and the pumping schedule would determine the overall recovery efficiency of the setup.
