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 minimized drawdowns and pumping costs, subject to constraints related to the system's response equations; demand requirements; drawdown limitation in saltwater intrusion control locations and pumping wells; and discharge bounds. The results are shown in the form of trade-off curves relating optimal pumpage rates and pumping costs to basinwide drawdowns and saltwater containment. Modeling results indicate that significant increases in total aquifer yield are possible with controlled drawdowns so that infringement of saltwater is prevented. Optimal pumping schedules differed, depending on the type of objective function used. The best policy appears to be the one in which the excess water pumped from the most productive wells is transported overland to meet local demands at less productive wells.

Development of water quality management strategies for the proposed Isikli reservoir Gunduz, O; Soyupak, S; Yurteri, C (1998-01-01) A two-dimensional laterally averaged hydrodynamic and water quality model (CE-QUAL-WS) is used to simulate the water quality behavior in the proposed Isikli Reservoir of the Ankara Water Supply System to determine appropriate strategies for the management of water quality.
Assessment of Dewatering Requirements and their Anticipated Effects on Groundwater Resources: A Case Study from the Caldag Nickel Mine, Western Turkey Peksezer-Sayit, Ayse; Cankara-Kadioglu, Cigdem; Yazıcıgil, Hasan (2015-06-01) Dewatering requirements of three open pits located in western Turkey and the impact of dewatering on groundwater resources were evaluated using a three-dimensional numerical groundwater flow model. The groundwater was modeled using MODFLOW software and the dewatering was simulated using the MODFLOW Drain Package. The drain cell configurations were determined by pit boundaries; invert elevations of drains corresponded to the bench elevations in the mining schedule, which varied dynamically among the three pi...
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...
Optimal operation of water distribution pumps considering water quality Altan Sakarya, Ayşe Burcu (American Society of Civil Engineers (ASCE), 2000-07-01) A new methodology has been developed for determining the optimal operation of water distribution system pumps with water quality considerations. The methodology is based upon describing the operation as a discrete time optimal scheduling problem that can be used to determine the optimal operation schedules of the pumps in distribution systems. The solution methodology is based upon a mathematical programming approach resulting in a large-scale nonlinear programming problem that cannot be solved using existi...
