Conceptual model development for Güzelyurt aquifer, North Cyprus

Fanta, Debebe Beyene
Water resources available in the North Cyprus are suffering from severe drought. In order to overcome this, there is a water diversion project being carried out in the North Cyprus by State Hydraulic Works (DSİ). The project is designed to supply about 75 million m3 of water annually for drinking and irrigation purpose from southern Turkey to Northern Cyprus via pipeline under Mediterranean Sea. The costal aquifer of Güzelyurt, which is located in North Cyprus, is currently the main source of potable water in the region. Apart from drinking water supply, the aquifer is also used for agricultural irrigation purpose in the Güzelyurt region that provides significant contribution to the economy of the country through citrus orchards. Recent studies have revealed that the amount of water extracted from the aquifer exceeded its safe yield capacity, thus causing the degradation of water quality in the aquifer due to seawater intrusion. The water diversion project of DSİ is expected to relieve the excessive stress on the Güzelyurt Aquifer and may help the aquifer recover from further deterioration. The primary objective of this research is to develop a conceptual model for the Güzelyurt aquifer, which is the most useful tool available for groundwater resource management. It provides the general 3-D picture of the aquifer geometry, including recharge, discharge and hydraulic characteristics of the aquifer. In addition, the conceptual model is also used to ease understanding the complex nature of the aquifer system and organize the associated field data so that the system can be analyzed effectively for the purpose of future water resources planning. The conceptual model of the Güzelyurt Aquifer was developed in Geographical Information Systems (GIS) and Groundwater Modeling System (GMS) software environment based on the available geological and hydrological data of the study area. Based on the objectives, the surface and subsurface structural framework: areal and vertical extent of aquifer has been determined and also internal and external boundary conditions of the aquifer have been established. Moreover, aquifer zones affected by excessive water withdrawal and seawater intrusion have been delineated.


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...
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...
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...
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...
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...
