Sustainable development and management of an aquifer system in western Turkey

Yazıcıgil, Hasan
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 flow in the aquifer system. The model has been calibrated under steady state and transient conditions. The resulting model was used to test seven management scenarios for a planning period of 21 years to determine the so-called safe yield and sustainable yield of the aquifer system and to investigate the potential impacts of four planned surface water reservoirs on groundwater resources in the basin. The results demonstrate that the continuation of the present pumping rates exceeds both the safe yield and the sustainable yield of the aquifer system. Consequently, the growing need for irrigation water should be met by the construction of the planned surface water reservoirs and the implementation of efficient water management policies and plans.


Investigation of sustainable development potential for Ulubey Aquifer System, Turkey
Burcu, Unsal; Hasan, Yazicigil (2014-06-06)
This study investigates sustainable development potential for Ulubey aquifer system which serves as an important water supply for Usak province (Turkey). In recent years, growing population, accelerating industrial activities and decreasing rainfall, as well as contamination of the surface water resources, made groundwater indispensable to meet the freshwater demands of Usak province. Therefore, a sustainable groundwater development plan has to be set up by determining the sustainable yield of the system, w...
Contamination risk assessment for groundwater of the Kucuk Menderes River basin, Izmir, Turkey
Pusatli, OT; Camur, MZ; Yazıcıgil, Hasan (2000-04-01)
A new water management plan is needed for the Kucuk Menderes River basin in Turkey, due to increasing water demand and decreasing quality of the groundwater. Vulnerability, quality and risk assessments were performed using a hybrid model containing both hydrogeological and hydrochemical parameters for managing irrigation waters in the basin. The relative contamination (quality) distribution of groundwater at present was established using an irrigation water quality index. The distribution shows the contamin...
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...
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...
Numerical model development for Güzelyurt aquifer, North Cyprus
Demir, Cansu; Ünlü, Kahraman; Akıntuğ, Bertuğ; Department of Environmental Engineering (2018)
Güzelyurt, coastal aquifer, which is an unconfined, is the most important, at the same time the largest drinking, municipal, and irrigational water resource in Turkish Republic of Northern Cyprus (TRNC). However, the aquifer has exceeded its safe yield capacity due to excessive and uncontrolled pumping over the years and the water quality has been seriously degraded due to seawater intrusion. The “TRNC Water Supply Project”, completed in June 2016, will annually supply about 75 MCM of water via pipeline und...
