Conference Object Groundwater Resources in Local Development Strategies: Case of Izmir(International Water Association, 2017) Velibeyoğlu, Koray; Yazdani, Hamidreza; Baba, AlperRural 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.Conference Object Akifere Yağıştan Süzülme Miktarının Sondaj Verileri Kullanılarak Tahmin Edilmesi: Alaşehir (manisa) Havzası(TMMOB Jeoloji Mühendisleri Odası, 2018) Tonkul, Serhat; Baba, Alper; Şimşek, Celalettin; Tayfur, Gökmen; Durukan, Seda; Kumanlıoğlu, Ahmet; Demirkesen, Ali CanSon yıllarda iklim değişikliğine bağlı su kullanımının artması ve buna ek olarak aşırı nüfus artışı, yeraltısuyu kullanımını arttırmakta ve su kaynaklarını tehdit etmektedir. Su kaynaklarının sürdürülebilirliğinin sağlanması için barajlar ve yapay göller inşa edilmekte, ancak bu yapıların geniş yüzey alanlarında çok fazla buharlaşma görülmektedir. Dolayısı ile yeraltı suyunun, buharlaşma kayıplarının yaşanmadığı direkt yağış ile beslenen yapay beslenmesi önem kazanmaktadır. Yapay beslenme, havzalardaki suyu fazla buharlaşmadan korur ve su kaynaklarının potansiyelini artırıp, sürdürülebilirliğini sağlar. Bu çalışma kapsamında nümerik metotlar kullanılarak, Alaşehir (Manisa) havzasında alüvyon akiferin beslenmesinin belirlenmesi amaçlanmıştır. Türkiye’nin batısında yer alan ve ülkenin %2’sini oluşturan Gediz Havzası, önemli bir yeraltı suyu potansiyelinin olduğu ve kullanıldığı alan konumundadır.Conference Object Effect of Urbanization on Groundwater Resources of Izmir City(İZSU, 2017) Baba, Alper; Yazdani, Hamidrezaİzmir is the third largest city in Turkey. Fiftysix percent of the drinking water of İzmir city is provided from groundwater resources. Halkapınar (located on Bornova Plain) is one of the important groundwater resources areas. This region is providing 16 % of İzmir drinking resources. The water withdraws from the Halkapınar wells is about 30 million m3 in recent years. The groundwater levels of Bornova plain are range from 1 m to 10m. This plain had been used as agricultural lands until the 1950s, while today they have been opened for settlement. In 1965 Bornova accommodated half of its population in rural areas after receiving so much immigration. It was inevitable to open the citycentre to housing and to consider the surrounding village areas as urban areas. By the year 2000, the rural population had already been melted into the urban population. The agricultural areas in rural parts of the country will have completely disappeared in 50 years' time. Much of the surface of the plain is rendered impermeable by buildings, roads and surface coverings. Because of this covering, groundwater recharge is reduced and increases and accelerates runoff the plain. The groundwater recharge from precipitation was about 27 % in 1925, but this amount dropped to 13% in 2012. Groundwater recharge from precipitation will be 1% in 2030. Hydrodynamic of plain is change because of excessive urbanization. Groundwater level of the plain still high because tall building makes a barrier for groundwater recharge points.
