Coasts are sensitive and dynamic areas against natural influences such as waves, winds, currents, and tides. Pressure of human activities also accelerate the change of coasts. Climate change and global sea level rise are other factors affecting the coasts. Therefore, the identification and protection of coasts, which are important in terms of socio-economically and natural environment, becomes an important issue. One of the main purposes of this study is to classify Mersin and İskenderun bays coasts according to their vulnerability to natural forces and anthropogenic factors using the Coastal Vulnerability Index (CVI) methods. In this study, five different CVI methods are used to evaluate the vulnerability of coasts. To easily adapt all these method a Geographic Informations System (GIS) tool has been developed. This GIS tool will facilitate researchers for CVI calculations. In addition, this tool will help decision makers to take the necessary precautions to protect coasts and to increase their resistance to natural and human effects on the coasts. According to the coastal vulnerability analyses, 151 km of the coastal zone is classified as very high vulnerable, 147 km as high vulnerable, 153 km as moderate vulnerable and 138 km as low vulnerable. In this study, the main parameters to affect the vulnerability are the coastal slope, land-use and population. High and very high vulnerable coasts occurred in coastal plains with low slope, weak geological and geomorphlogical structures, high socio-economic values. These high and very high vulnerable coasts are mainly located between Silifke and Yumurtalık coasts.

Composite reliability model for local scour around cylindrical bridge piers Yanmaz, Ali Melih (2001-06-01) Bridge scour is an extremely complex phenomenon because of the random characteristics of sediment laden flow in close proximity to piers and abutments. This occurrence leads to high uncertainties and unavoidable risk in bridge pier and abutment design. In this study, a composite reliability model is developed for the reliability assessment of bridge pier scour using static resistance - loading interference. Based on the physical interpretation of the phenomenon and a statistical analysis of the available in...
Measurement and evaluation of the hydrodynamics and secondary currents in and near a strait connecting large water bodies - A field study Gueler, Isikhan; Yueksel, Yalcin; Yalçıner, Ahmet Cevdet; Cevik, Esin; Ingerslev, Christian (Elsevier BV, 2006-09-01) The straits connect two large water bodies show highly strong and stratified currents related to meteorological, morphological and hydrodynamic conditions. In some cases, spatial and temporal changes of the stratified currents and their thickness, direction and magnitude are so complex. This complexity directly affects the circulation pattern in the region, water exchange between both ends of the straits and migration of fish species. In order to understand general characteristics of this kind of straits an...
Wave - Induced Suspended Sediment Flux Degradation due to Emergent Vegetation Koroglu, Aysun; Elginoz, Nilay; Oğuz, Elif; Kabdasli, M Sedat (2012-06-22) It is well known that sediment movement is affected by aquatic vegetation under flow and wave conditions. However this impact is not fully understood yet. The aim of this study is to determine the effect of emergent vegetation on suspended sediment flux under wave conditions. In this context, an experimental study was conducted and wave orbital velocities and suspended sediment concentrations are measured through 4 m long emergent reeds under regular waves. Suspended sediment fluxes were calculated and the ...
Wind and wave climate in Eastern Mediterranean basin Kışlakcı, Ahmet Umud; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2008) The wind and wave (wind wave/swell wave) climate has an important role in the design and operation of coastal and marine structures, harbors and ports. The objective of this study is to identify the statistical characteristics of the winds, wind waves and swell waves in Eastern Mediterranean, and coastline of Türkiye. For this purpose, the data of wind speed and direction, swell and wind wave height, period and direction for a certain duration with the six hours time intervals are obtained from ECMWF for th...
Dissolved, Colloidal and Particulate Iron in Hydrothermal Vent Fluids and Rising Plumes from Broken Spur and Rainbow, Mid-Atlantic Ridge Yücel, Mustafa; Le Bris, Nadine (2019-08-23) Mid-Atlantic Ridge (MAR), with its slow spreading character, forms geological heterogeneity throughout the ridge system by deep crustal faults and their resultant tectonic valleys, which result in existence of different types of hydrothermal vent fields. Therefore, examining MAR opens a gate to understand the concentration ranges of ecosystem- limiting metals emanating from compositionally distinct hydrothermal settings for both near-field chemosynthetic ecosystems and far-field transport into the ocean int...
