“…Models are the best methods known for evaluating flow processes in the subsurface (e.g. Senthilkumar and Elango, 2004) and also provide impressions of the continuous spatial and vertical variations in the key aquifer parameters Ophori, 1999;Ebraheem et al, 2003;Uddameri and Kuchanur, 2007;Yidana, 2011). It is the proper use of numerical groundwater flow models that can lead to the proper definition of regional and local recharge and discharge areas.…”

“…Numerical groundwater flow and solute transport models can also be used to estimate hydraulic parameters (e.g. Ebraheem et al 2002Ebraheem et al , 2003Sefelnasr 2007); and predict aquifer responses to different pumping scenarios and climate conditions (e.g. Sherif and Singh 1999;Gossel et al 2004Gossel et al , 2008.…”

Groundwater pumping from Kalbha and Fujairah coastal aquifer of the United Arab Emirates (UAE) has increased significantly during the last two decades to meet the agriculture water demands. Due to the lack of natural replenishment from rainfall and the excessive pumping, groundwater levels have declined significantly causing an intrusion of seawater in the coastal aquifer of Wadi Ham. As a result, many pumping wells in the coastal zone have been terminated and a number of farms have been abandoned. In this paper, MODFLOW was used to simulate the groundwater flow and assess the seawater intrusion in the coastal aquifer of Wadi Ham. The model was calibrated against a five-year dataset of historical groundwater levels and validated against another eleven-year dataset. The effects of pumping on groundwater levels and seawater intrusion were investigated. Results showed that reducing the pumping from Khalbha well field will help to reduce the seawater intrusion into the southeastern part of the aquifer. Under the current groundwater pumping rates, the seawater will continue to migrate inland.

“…They have been used effectively in such countries as India, China, Pakistan among others, to influence groundwater management paradigms (e.g. Shamir et al, 1984;Willis and Finney 1988;Finney et al, 1992;Emch and Yeh, 1998;Ebraheem et al, 2003;Zhou et al, 2003;Uddameri and Kuchanur, 2007) and prove to be universal in their applications. Simulation models are more effective when combined with optimization models whereby a set of management objectives are achieved in the midst of several environmental and socioeconomic constraints.…”

A groundwater flow simulation model was developed using available hydrogeological data to describe groundwater flow in the Afram Plains area. A nonlinear optimization model was then developed and solved for the management of groundwater resources to meet irrigation and household needs. The objective was to maximize groundwater extraction from the shallow aquifers of the southern Voltaian Sedimentary Basin that underly the area, for irrigation activities. This would improve food security, raise the standard of living and ultimately help towards poverty alleviation in the rural communities that constitute the Afram Plains district. The calibrated flow model is in tandem with the general hydrochemical evolution of groundwater in the area and fits the observed data with about 98% degree of confidence. The study reveals that groundwater resources, if fully developed, may not be the limiting factor in the development of the irrigation industry, and has tremendous potential to meet current and future irrigation needs. Six groundwater management periods (January 2007-December 2013) were used for the study, with the quantity of irrigable land available, and the groundwater level drawdown as the main constraints that limit the maximization of groundwater extraction from wells for irrigation and household purposes. Maize was used as the single irrigation crop because maize appears to be the staple food and farmers are familiar with it in the area. It was determined from this pilot study, that profit from maize irrigation in the Afram Plains area could rise from US$ 301,000 in 2007 to over US$ 3.5million at the end of the last management period (2013) as irrigation practice is improved, and the economic strength to increase the acreage for irrigation improves. Even with these margins of profit, the drawdown constraint was not reached in any of the management periods. It is expected that recharge from the irrigation water would reclaim the lost hydraulic head. The single significant constraint was the amount of land area that could be developed for irrigation in the area. The profit obtained per unit cubic meter of water used also improved over the same management period.
