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 (1976) is combined with Genetic Algorithm (GA) to optimize the maximum benefit in a coastal aquifer. Injection wells are added as an artificial recharge to prevent seawater intrusion. The objective is to optimize both pumping rates and locations of injection wells. The model is applied to a previous work by Mantoglou (2003). Two different methods are utilized. First locations and discharge values are optimized, simultaneously. Then, a three-step GA method is introduced where discharge rates and locations are optimized, in an iterative manner.

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...
Comparison of groundwater recharge estimation techniques: a case study from the Kucuk Menderes River basin in Turkey Gundogdu, A; Yazıcıgil, Hasan; Kirmizitas, H (2000-04-01) Quantification of groundwater recharge is a basic prerequisite for efficient groundwater management. While there are several approaches to estimating groundwater recharge rates, some of the approaches proposed cannot be applied in basin-wide hydrogeological investigations due to a lack of data. Thus, some conventional recharge estimation techniques for which data are most often available have to be used in estimating groundwater recharge. In this study, water level fluctuation, the precipitation vs water le...
Alternative solutions for long missing streamflow data for sustainable water resources management Mesta, Buket; Akgün, Ömer Burak; Kentel Erdoğan, Elçin (Informa UK Limited, 2020-08-01) Sustainable water resources management requires long time series of streamflow data. In this study, a Takagi-Sugeno fuzzy rule-based (FRB) model is developed to reconstruct long periods of missing daily streamflow data which is a common problem in developing countries. The FRB model uses observations of neighbouring stream gauges, and thus is advantageous regarding data and time requirement compared to physical models. With the proper set of inputs, the FRB model provides better estimates than the hydrologi...
Application of a data mining approach to derive operating rules for the Eleviyan irrigation reservoir Sattari, M. Taghi; APAYDIN, HALİT; ÖZTÜRK, FAZLI; Baykal, Nazife (2012-01-01) Optimum irrigation reservoir operation is a significant issue for water management decision makers. In this study, we used 4 different datasets of monthly amounts of water to be released from the Eleviyan irrigation reservoir in Iran as inputs in a data mining model; "if-conditional" operating rules were determined as outputs. Operating rules derived from data mining and rules obtained from an optimization model were in high concordance, especially between the 2 datasets from the preconstruction period, wit...
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...
