    Groundwater Resources and Quality in Syria
    (Elsevier, 2021) Baba, Alper; Karem, Ruwad AL.; Yazdani, Hamidreza
    The resources of groundwater and its pollution in Syria are identified, and pathways of contaminants to groundwater are described. Then, suggestions for improvement of groundwater quality in Syria are evaluated. Syria is located in a region where water scarcity is dominant. About 87% of all water in Syria is mainly used for irrigation, with almost 60% of this water taken from groundwater resources. The rest is used for domestic and industrial purposes, which account for 9% and 4%, respectively. Due to over-pumping and the increase in the number of unsustainable wells observed in recent decades, groundwater is quantitatively deteriorating. In general, sources of groundwater contamination fall into two main categories: natural and anthropogenic sources. Important sources of natural groundwater pollution include climate effects. About 43% of groundwater has a high concentration of SO4 and/or NaCl. This is specifically dominant in the eastern region of Syria due to the harsh environment where precipitation is relatively low, and evaporation is high. One of the major sources of anthropogenic groundwater contamination is civil war. Most of the damaged regions are located on permeable rocks, which increases the probability of groundwater contamination due to chemical weapons (CW) used. It is vital to manage and control groundwater resources well. With the increase in water contamination and with the absence of poor water management, access to drinking water will be more of a problem than it is now.

    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.

    Groundwater in Local Development Strategies: Case of Izmir
    (IWA Publishing, 2018) Velibeyoğlu, Koray; Yazdani, Hamidreza; Baba, Alper
    This study takes into account groundwater in local development strategies of Izmir, in which rapid and uneven development has occurred in recent decades. Therefore, resilience thinking is needed in the future development of the city-region. To this end, the paper aims to make an analysis of recently completed asset-based local development strategies for Izmir city towards water resiliency. The methodology has two main steps. Firstly, by using spatial interaction analysis of peninsula and river basins, potential vulnerabilities and risks are indicated. Secondly, a stratified model of strategy evaluation is conducted by scrutinizing the existing layered approaches. Then, these models were applied to all strategic decisions including water resources and indicated a high level of consistency to achieve sustainable and resilient use of blue-green infrastructure in the future of Izmir’s metropolitan area. Local assets, including water resources, are the backbone of future development of the Izmir city-region. Therefore, usage of local assets in a multi-level perspective of strategy development needs to be understood. The stratified model denotes that special emphasis should be given to different river basins in different levels. This study illustrates that synergy management is needed between different layers of local development strategies, in which the role of urban and rural households is of the utmost importance.
