Coastal scenic assesment using fuzzy logic approach

Karakaya, Selami Tansel
This thesis analyzes the coastal landscape evaluation that is strongly rooted in the man-environment tradition. Scenery is a natural resource and managers need to attempt the evaluation of scenic resources in an objective and quantitative way that can be utilized mainly in landscape preservation and protection. The thesis will try to find an objective way in evaluation of the coastal scenery by using fuzzy logic mathematics and public perception studies. Using mathematical model developed within the frame work of the present study the selected 22 sites in Turkey were evaluated and then classified.


A case study on the stability of berm type coastal defense structures
Fışkın, Gökçe; Ergin, Ayşen; Department of Civil Engineering (2004)
Coastal defense structures have primary importance from obtainabilty of resources and benefits served by the coastal regions point of view. However, the construction of coastal defense structures demand a high amount of investment. Therefore, in order to reduce the risk of collapse of these structures, model studies should be carried during the design process. In this study, model investigations were carried out on Eastern Black Sea Highway Project regarding the serviceability and damage thus stability para...
Improving Coastal Vulnerability Assessments to Sea-Level Rise: A New Indicator-Based Methodology for Decision Makers
Özyurt Tarakcıoğlu, Gülizar; Ergin, Ayşen (2010-03-01)
Integration of impacts of sea-level rise to coastal zone management practices are performed through coastal vulnerability assessments. Out of the types of vulnerability assessments, a proposed model demonstrated that relative vulnerability of different coastal environments to sealevel rise may be quantified using basic information that includes coastal geomorphology, rate of sea-level rise, and past shoreline evolution for the National Assessment of Coastal Vulnerability to Sea-Level Rise for U.S. Coasts. T...
Coastal Scenery Assessment by Means of a Fuzzy Logic Approach
Ergin, Ayşen (2019-01-01)
Landscape is a major element affecting people's life quality and coastal landscape evaluation is strongly rooted in the man-environment tradition. Coastal areas, all over the world, are under threat due to the conflicting requirements that rely on natural scenery of such as habitation, recreation, and industry. Since 'coastal scenery' is a natural resource, it has to be evaluated in an objective and quantitative way to provide a means of comparison against coastal activities and for environmental impact ass...
Intermetallic phase formation at Fe-Al film interefaces
Temizel, Güvenç; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2006)
This thesis presents the formation mechanism of intermetallics formed at Fe-Al film interfaces. Al thin films with different initial film thicknesses were coated on low carbon steel substrates by physical vapor deposition (PVD). By annealing the system at different temperatures and for different time intervals, several intermetallic phases were observed. X-Ray, SEM and EDS studies showed that intermetallic phases FeAl2 and Fe2Al5 are most dominant phases which were observed and they formed sequentially on t...
Texture softening and strain instability in F.C.C. metals: Plane-strain deformation
Öztürk, Tayfur; Davies, Gwilym J. G (Elsevier BV, 1987-9)
An analysis was carried out into texture induced softening and the resulting strain instability in plane-strain deformation. A macroscopic model was employed in the analysis which viewed the deformation as the juxtaposition of suitably disposed positive and negative simple shears. With this model, the textural contribution to the rate of deformation hardening was computed in terms of a texture softening factor, S, this in a form that could readily be incorporated into the relevant conditions for strain inst...
