“…See, for example, Wang and Zheng (1996) and Jha et al (2009). Moreover, these studies have predicted the best withdrawal at all production wells in order to meet the yearly demand while avoiding land subsidence; that is, the objectives have a hydrologic nature, whereas the constraints have an economic or environmental nature (for example, see Don et al 2006). Finally, these studies have aimed at maximising the net benefits from groundwater recharge; that is, the objectives were economic in nature, and no constraints were considered.…”

This paper applies optimal-control theory to develop groundwater exploitation strategies that account for potential climate change patterns in Brazil. Numerical experiments showed that whether climate change only affects groundwater quantity or whether it affects both groundwater quantity and quality, Brazilian water institutions will be able to implement optimal, equitable groundwater management strategies. However, they may be unable to achieve justice between current generations, while the economic, social, and environmental sustainability is likely to be favoured by a large regional groundwater availability. Institutional sustainability is ensured by the principles and institutions established by Brazil's 1988 Constitution and by Law 9.433/97. Some sources of misunderstandings between managers and the research community are dealt with by suggesting directly applicable management strategies that accommodate stakeholder perceptions and desires. Some potential water policies based on the modelling results are discussed, with water conservation and water subsidies turning out to be beneficial for current and detrimental for future generations, respectively; in contrast, current generations paying for water at its social opportunity cost and being more concerned for future generations would benefit current generations.

“…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. Don et al (2006) for instance coupled a numerical simulation model with an optimization model to predict groundwater response to settlement and to determine the optimal safe yield for groundwater without violating physical, environmental and socio-economic constraints in the Shiroishi area in the Saga Plain in Japan. This model enabled them to determine the effects of climate and various pumping scenarios on the aquifer system.…”

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.

Due to overcapacity, the current airport of Yogyakarta is going to be replaced with a new one, which is located in Wates coastal area, Kulon Progo District, Yogyakarta Special Province, Indonesia. One of the consequences of the development of the new airport is groundwater abstraction due to the airport's needs and related supporting activities. An excessive withdrawal of groundwater in the new airport will potentially change the system and the pattern of groundwater flow. Therefore, groundwater modeling should be done to predict the impact of groundwater abstraction in this area. MODFLOW code is used to simulate the groundwater flow and the impact of groundwater pumping in the Wates coastal aquifer. The model is calibrated using water level data from 40 wells in the research area. The results show that the calculated values are fit to the measured data, which indicates that the model is reliable. The effects of groundwater pumping on water table and seawater intrusion are investigated using a calibrated model. The results show that the pumping scenario from the airport area causes the groundwater level to drop 0.75 m and seawater intrusion inland to increase around 100 m.
