Modeling and development of a groundwater management plan for Ulubey aquifer system, Uşak-Turkey

Ünsal Erdemli, Burcu
The purpose of this study is the characterization and modeling of Ulubey aquifer system which serves as an important water supply for Uşak province located in inner parts of the Aegean Region in Turkey. In recent years, growing population, accelarating industrial activities and on the contrary decreasing rainfall and contamination of the surface water resources made groundwater indispensable to meet domestic, agricultural and industrial water demands of Uşak province. All these facts necessitate the development of a groundwater management plan, which this study aims to end up with. For this purpose, every single component of the recharge/discharge mechanisms of the groundwater budget of the aquifer system should conceptually be comprehended. However, due to lack of data, all of the components can not be precisely determined. Hence, a mathematical groundwater flow model successfully calibrated under steady state conditions, is utilized to calculate the missing components of the groundwater budget and also to test the effects of increased pumping rates for irrigational and domestic uses to supply the increasing demand in the future. For this purpose, three management scenarios are set up under transient conditions over a planning period of 20 years. Drawdown maps, groundwater budgets and groundwater level hydrographs are utilized to observe the effects. The results of these simulations proved that neither of the tested management scenarios creates significant drawdowns or change in groundwater reserve of the Ulubey aquifer system.


Determination of the dynamic characteristics and local site conditions of the plio-quarternary sediments situated towards the north of Ankara through surface wave testing methods
Eker, Arif Mert; Akgün, Haluk; Department of Geological Engineering (2009)
The purpose of this study is to assess the engineering geological and geotechnical characteristics and to perform seismic hazard studies of the Upper Pliocene to Quaternary (Plio-Quaternary) deposits located towards the north of Ankara through surface wave testing methods. Based on a general engineering geological and seismic site characterization studies, site classification systems are assigned in seismic hazard assessments. The objective of the research is to determine the regional and local seismic soil...
Mineralogical and geochemical properties of messinian gypsum occurence in Polatlı Sazılar region, Ankara
Çakmak, Hayriye; Köksal, Fatma; Department of Geological Engineering (2008)
The objective of this study is to understand the petrographical, mineralogical and geochemical characteristics of Messinian (Upper Miocene) gypsum occurence in Polatlı Sazılar region, Ankara and to determine the impurities associated with gypsum. Moreover, it is aimed to interpret the usability of this raw material with impurities in plaster and plasterboard production based on industrial standards. Based on petrographical study, the first variety of gypsum which have different physical properties is white ...
Post-paleocene deformation in Kalecik region, East of Ankara, Turkey
Kasımoğlu, Pınar; Rojay, Fuat Bora; Department of Geological Engineering (2010)
In order to understand the tectonic evolution of the Kalecik region (Ankara, Turkey), a structural field study was performed in a selected area located in the east of Kalecik, where mostly imbricated thrust sheets of the Cretaceous Ophiolitic melange crop out. In the study area, the Cretaceous Ophiolitic melange, Cretaceous radiolaria-bearing sequences and the Paleocene units are all intruded by sub-vertical dykes. The attitudes of planar structures (dykes, beds and faults) and the kinematic data measured o...
Artificial recharge of groundwater in Küçük Menderes River Basin, Turkey
Peksezer, Ayşe; Yazıcıgil, Hasan; Department of Geological Engineering (2010)
Küçük Menderes River Basin located in western Turkey has been facing continuous groundwater level decreases for the past 30 years. In dry periods, irrigation demand is completely met by pumping from groundwater system, which reduces water levels significantly. This provides enough storage to be recharged in wet seasons when streams are running. However, increased runoff in wet season are not utilized neither for irrigation nor for recharge and lost to the Aegean Sea without being infiltrated. Hence, surface...
Assessment of water supply impacts for a mine site in Western Turkey
Ağartan, Elif; Yazıcıgil, Hasan; Department of Geological Engineering (2010)
A certain amount of water is required for a mine site located in Turgutlu in Western Turkey to be used in mining processes. The purpose of this study is to assess the impacts associated with meeting water supply requirements for the mine. Scope of the study involves determination of the alternative water resources, the assessment of impacts associated with each resource and the selection of the most feasible alternative in the aspect of environmental and technical effects. Three alternatives suggested to su...
