Izmir Bay is one of the great natural areas of the Mediterranean and compares well with similar coastal areas in the world. Izmir which is the main urban area around the Bay is an important industrial, commercial and cultural focal point. It has the second biggest harbour and is the third largest city in the country. The Izmir metropolitan area has experienced rapid population increase which placed an intense pressure on the environment of the bay, housing, infrastructure and social services. The main sources of pollution in the bay are domestic and industrial effluents which account for 50% of the observed organic pollution. Rivers discharging to the Izmir Bay carry mostly industrial discharges. The main forms of pollution in the Izmir Bay are organic pollution, nutrients, pathogenic organisms and toxic material carried by rivers. Scientific evidence suggests if no pollution control measures are taken immediately pollution in the Bay will soon reach a critical level leading to the collapse in the ecosystem. With this understanding Izmir Sewerage and Stream Control Project which foresees the reestablishment of the Bay's water quality was started in 1983. The preliminary assessment of the costs and benefits of the project suggests that the benefits of the proposed pollution control system could significantly outweigh the costs of the control measures by a factor of about eight.

The Genesis of early state formation in the Aegean Prehistoric Cultures : Liman Tepe and Bakla Tepe as a case study Durğun, Pınar; Tuna, Numan; Department of Settlement Archaeology (2012) The Izmir Region is located in the heart of the Western Anatolian coastline and forms a natural bridge between the Anatolian mainland and the Western Aegean. The region is connected to Central Anatolia through deep valleys and is linked to the Aegean Sea via many harbor sites along the coast. The architectural features and the other remains (such as pottery, metal objects etc.) found in and around those architectural context can provide the information about the genesis of the urbanization. With reference t...
Assessment of environmental and engineering geological problems for the possible re-use of an abandoned rock-hewn settlement in Urgup (Cappadocia), Turkey Ulusay, Resat; Gokceoglu, Candan; Topal, Tamer; Sonmez, Harun; Tuncay, Ergun; Erguler, Zeynal Abiddin; Kasmer, Ozgu (2006-07-01) The Cappadocia Region of Central Anatolia having a very distinct culture is one of the attractive touristic sites of Turkey due to its spectacular and unique landforms and historical heritages. In this region, the structures carved into thick to massive tuffs survived and kept their original integrity for a number of centuries. Environmental and anthropological factors at the Cappadocia Region have been the main reasons for extensive subsurface and multi-purpose use in the past and present. In addition, the...
Water Quality Assessment of a Shallow Lake in a Specially Protected Area Lake Mogan Ankara Turkey Kiraz, Melike; Alp, Emre (null; 2015-06-01) Mogan and Eymir Lakes are two shallow lakes, interconnected hydrologically in the close vicinity of Ankara, Turkey. A total of 245 km² of the total 971.4 km² watershed is under environmental protection status as "Gölbaşı Specially Protected Area". Potential impacts from extensive agriculture, recreation, incomplete infrastructure and other human activities, such as residential settlements, are discussed with reference to previous and more recent pollution monitoring. Six monitoring stations enabling follow-...
Time Series Modeling and Drought Frequency Analysis for the Annual Rainfall of North Cyprus Yücel, Nazlıcan; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2021-9) Cyprus which is the third biggest island in the Mediterranean Sea is located in the south of Turkey. The island has a semi-arid climate The rainfall is the main source of the island, therefore, the analysis of existing rainfall data across the island has vital importance for a better sustainable water resource management. In this study, annual rainfall data of 33 meteorological stations across North Cyprus were used. The main objectives of the study are modeling the annual observed rainfall of North Cyprus ...
Integrated Watershed Management for Lake Mogan with the focus of Agricultural Diffuse Pollution Özcan, Zeynep; Başkan, O; Düzgün, Hafize Şebnem; Kentel, Elçin; Alp, Emre (2015-09-25) Lake Mogan located 20 km south of Ankara, Turkey has a watershed area of 970 km2, and it is dominated by areas with dry agricultural practices (50%) and graze lands (31%). Intense agricultural activities and fast urbanization rates are the most important factors affecting the water quality in Lake Mogan. There has been several management alternatives suggested to improve the water quality in Lake Mogan. In 2008, the municipality implemented lake augmentation strategy to increase the water level since it dro...
