    Evidence for Sea Water Intrusion in Karstic Aquifer of Karaburun Peninsula, Nw Turkey
    (International Water Association, 2017) Baba, Alper; Gündüz, Orhan; Şimşek, Celalettin; Elçi, Alper; Murathan, Alim; Sözbilir, Hasan
    Karstic aquifers are considered to be significant sources of groundwater and are mostly under threat due to sea water intrusion in many parts of the world. Seawater intrusion is also a common problem on karstic aquifers of Karaburun Peninsula in north of Mediterranean Region. The hydrogeology of Karaburun Peninsula is fairly complex and is mostly characterized by highly permeable karstic formations with significant water storage in an otherwise water scarce area. The karstic aquifers of the region were recently found to be under severe salt water intrusion, which significantly altered the position of fresh water/sea water interface as a result of excessive pumping and fault zones controlling the karstic network.

    Assessment of Water Quality Related To Lead/Zinc Mines in Umurbey Dam Basin, Northwestern Turkey
    (International Water Association, 2017) Şanlıyüksel Yücel, Deniz; Baba, Alper
    The purpose of this study is to determine hydrochemical properties of the water resources and to assess the potential environmental consequence of the mining activities in Koru and Tesbihdere lead/zinc mine districts, and investigate detrimental effects caused by mining activities on the water resources and sediment quality in Umurbey dam basin (Biga Peninsula, NW Turkey). Cadmium, Cu, Fe, Mn, Pb and Zn concentrations in sediments downstream of Tesbihdere and Koru mines and in Umurbey dam sediments are higher than average values of world river sediments.

    Groundwater Resources in Local Development Strategies: Case of Izmir
    (International Water Association, 2017) Velibeyoğlu, Koray; Yazdani, Hamidreza; Baba, Alper
    Rural socio economic development has gained utmost importance in Turkish Metropolitan Municipalities within the frame of recent legal changes extending boundaries towards their peripheral areas. With this regard, Ġzmir Metropolitan Municipality has completed series of local development strategies aiming at the sustainable development of the city‘s rural hinterland. For three fertile sub region of Izmir, namely as Yarımada, Gediz Bakırçay and Küçük Menderes, local development strategies were prepared consecutively. In the framework of local development strategies; agriculture, tourism, settlement pattern and culture, local innovation and entrepreneurship, and environmental issues and water resources were examined as project themes. Among them, water resources has utmost important since the local development of whole sectors are largely dependent on them. Therefore, local development strategies have underlined the reality of river basins and potentials and limitations on groundwater resources due to the fact that surface waters have already been contaminated.

    The Impacts of Planning Criteria’s on Groundwater Sources: Case of Izmir New City Center
    (International Water Association, 2017) Yazdani, Hamidreza; Baba, Alper
    Cities with historical background, according to their geographic or economic alteration generally possess different town centers. Mostly for better protection against human or non-human factors the center of cities are relocated. The city of Ġzmir is one the magnificent case of city center resettlements. The premier location of city that is estimated to be 5000-8000 years before was in Bornova reeds in the north. Far from the sea and as results of serious disease the settlement relocated to Smyrna in Bayraklı. Smyrna was then abounded after massive earthquakes. Pagos hills (Kadifekale) with its great defending potential become the next city of Smyrna. Then, the economic value of harbor and rail-way moved the city to the cost. In all this location selection, geographic characters present crucial role in optimizing the decision.

    Evaluating Impacts of Urbanization on Recharge of Groundwater Resources: Case Study: Bornova Plain (izmir/Turkey)
    (International Water Association, 2017) Yazdani, Hamidreza; Kılıç, Çılga; Baba, Alper
    Increasing the World‘s population and industrialization in parallel with urbanization has created serious problems on water resources. Over the next forty years it is expected to add 2,5 million people on world population. To fulfill the needs of increasing population, the water demand will increase but the increasing of demand towards water is more rapid than increasing of population. Urbanization is a global phenomenon that is quickly altering the physical structure of any region. Bornova plain is located in water basin of Ġzmir where it is the most important settlement of the Aegean Region from the ancient ages to the current era. In this study, impacts of urbanization and population growth on groundwater resources were analyzed using GIS in Bornova Plain, where it is one of the most important groundwater aquifers and it supports about 16% of domestic water resources of Izmir City.

    Investigation of Groundwater Recharges Mechanism in Alasehir Plain: From Physical Characterization To Modelling
    (International Water Association, 2017) Şimşek, Celalettin; Baba, Alper; Aksoy, Niyazi; Demirkıran, Zülfü; Hasözbek, Altuğ; Tayfur, Gökmen; Kumanlıoğlu, Ahmet; Durukan, Seda; Demirkesen, Ali Can; Murathan, Alim; Çağıran, Ömer; Akdeğirmen, Özgün; Tonkul, Serhat
    Characteristics of aquifer that allows the flow of groundwater, recharge and discharge mechanism effect the available groundwater potential. In order to determine the available potential of groundwater, the budget components are the most important parameters. In general, different analogical methods are applied in different countries, instead of using measurable data. Determination of the groundwater recharge is the most difficult parameter to be measured among the hydrological budget parameters. In general, the analogical methods are insufficient to determine the groundwater recharge rate. Precipitation, evaporation-transportation and runoff can be measured from the surface meteorological station. However, estimation of groundwater recharge cannot be measured directly. At the moment of climate change, visualization of the spatial distribution of the groundwater recharge estimation and mapping are needed. Therefore, improvements of easy groundwater recharge techniques are very important tools for groundwater basins to develop the water management planning.

    Numerical Flood Models in the Projected Waste Disposal Site in Izmir
    (International Water Association, 2017) Akdeğirmen, Özgün; Baba, Alper
    Determination the location of waste disposal sites has always been a challenge for researchers and government organizations. Since the problem on fundamental level is complicated and bound to several of parameters. The effects of the project from the perspectives of economic, social and environmental should be evaluated delicately. This study focuses on surface water accumulation and flood effects; one of the several criteria at the step of decision making to determine the location of waste disposal sites. As a candidate area Yamanlar region (Izmir), where is located on the caldera, is chosen for examining from surface water effects.
