Three ground-water management models were developed to determine the optimal planning and operating policies of a multiaquifer system in eastern Saudi Arabia for an eight-year planning period. The modeled system, which consisted of the Alat, Khobar, and Umm Er Radhuma aquifers, was represented by a three-dimensional simulation model included in linear and quadratic optimization models using response functions. Yearly optimal pumping policies were determined for 52 well fields under three management objectives that maximized agricultural water withdrawals and minimized total drawdowns, and pumping costs subject to constraints related to the system's response equations, demand requirements, drawdown limitations, and discharge bounds. Multiobjective analyses were conducted to develop trade-off curves relating increased agricultural water production to drawdown, aquifer dewatering, and pumping costs. Modeling results show the agricultural water production could be increased by almost two and a half times without causing dewatering. Optimal pumping schedules differed, depending upon the type of objective function employed. The best option appears to be the one in which extensive water transport is allowed between municipal well

Optimal management of a coastal aquifer in southern Turkey HALLAJI, Khosrow; Yazıcıgil, Hasan (1996-01-01) Seven ground-water management models were developed to determine the optimal planning and operating policies of a costal aquifer in southern Turkey threatened by saltwater intrusion. Steady-state and transient finite-element simulation models, representing the response of the system, are linked to linear and quadratic optimization models using response functions. Optimal pumpage policies were determined for 94 wells under three management objectives that maximized agricultural water withdrawals and minimize...
Optimal management of coastal aquifers using heuristic algorithms Demirbaş, Korkut; Altan Sakarya, Ayşe Burcu; Önder, Halil; Department of Civil Engineering (2011) Excessive pumping in coastal aquifers results in seawater intrusion where optimal and efficient planning is essential. In this study, numerical solution of single potential solution by Strack is combined with genetic algorithm (GA) to find the maximum extraction amount in a coastal aquifer. Seawater intrusion is tracked with the potential value at the extraction well locations. A code is developed by combining GA and a subroutine repeatedly calling MODFLOW as a numerical solver to calculate the potential di...
Sustainable development and management of an aquifer system in western Turkey SAKIYAN, J; Yazıcıgil, Hasan (2004-02-01) This study presents the establishment of sustainable development and management policies for the Kucuk Menderes River Basin aquifer system in western Turkey. Geological, hydrogeological, and geophysical data are used conjunctively to define various hydrogeological units and their geometry. Distributions of hydraulic-parameter values and recharge are estimated by geostatistical methods and hydrologic simulations, respectively. A finite-difference groundwater flow model is used to represent the unconfined flo...
Sustainable buildings for healthier cities: assessing the co-benefits of green buildings in Japan Balaban, Osman (2017-10-01) High concentrations of people and economic activities in urban areas have strengthened the links between cities, health and the environment. Cities are not only responsible for environmental and health problems but also they hold the key for a greener economy and a sustainable future. Urban built environment is a policy field where appropriate policies and actions could yield significant human and ecological benefits. Among different elements of urban built environment, buildings deserve particular attentio...
Scenario Planning for Water Resources A Saudi Arabian Case Study Dejong, Remy Lucıen; Yazıcıgil, Hasan; Allayla, Rashıd Ibrahım (1989-01-01) Uncommonly rapid development of the oil-rich Eastern Province of Saudi Arabia has led to heavy stresses on the local groundwater resources and there has arisen concern for the adequacy of supply to sustain future growth. Whereas oil is the only significant export commodity, the demand for it has an important and immediate impact on water exploitation activities. In this article four development scenarios are considered, each resulting in a specific water abstraction pattern. The hydrologic consequences of e...
