Rubble mound breakwaters are one of the most common coastal defense structures constructed around the world. Hudson (CERC, 1977; CERC, 1984), Van der Meer (1988) and Van Gent et al (2003) are the major stability formulas that are used to find the armour stone weight of rubble mound breakwaters. In the first part, a comparative study on major stability formulas is carried out to discuss the discrepancies in application of these design formulas. A computational tool Design Armour Stone (DAS) is developed within this study by defining the application limits of Van der Meer and Van Gent et al formulas tested by physical model experiments under appropriate design conditions. In the second part, design water level which is an important parameter affecting the armour stone size is investigated. Components of change in mean water level that affects design water level within economic life of a coastal structure are discussed. Effect of design water level on armour stone size of a coastal structure is analyzed by a computational tool developed in this study called Design Water Level Determination (DWLD) considering Hudson, Van der Meer and Van Gent et al approaches. Current deterministic approach is upgraded by the use of DWLD in order to find the most critical design water level in economic life of a rubble mound coastal structure. In the final part of this study, a case study is conducted in Aliaga, Izmir, Turkey. DWLD and DAS are applied to this region in order to show discussions in a real case study. The outcomes of these studies can be used as a guide in design of rubble mound breakwaters for practical purposes.

A Comparative study on stability and overtopping performances of reshaping berm breakwaters
Bezazoğlu, Semih; Baykal, Cüneyt; Güler, Işıkhan; Department of Civil Engineering (2016)
Berm type rubble mound breakwaters are preferred by engineers due to their relative advantages in economy and implementation compared to conventional rubble mound breakwaters. In this study, a previously constructed hardly reshaping berm breakwater protecting a filling area used as an airport between Ordu and Giresun cities in the Black Sea Region is compared to several alternative reshaping (partly or fully) models under the same stability and serviceability conditions by physical model experiments. In the...
A case study on the submerged berm type coastal defense structures
Özler, Başar; Ergin, Ayşen; Department of Civil Engineering (2004)
Coastal defense structures are built in order to protect valuable coastal regions from the destructive effects of the waves. Due to the cost of coastal defense structures and the economical potential of the coastal regions, failure of such structures could cause loss of high amounts of investment. Therefore in the design and construction of coastal structures, it is of vital importance to achieve an optimum design which is not neither underdesigned nor overdesigned. In this study, Submerged Berm type coasta...
A Comperative economical analysis on the design of berm breakwater: case study on Ordu-Giresun airport berm breakwater
Atak, Doğukan; Özyurt Tarakcıoğlu, Gülizar; Güler, Işıkhan; Department of Civil Engineering (2016)
Berm breakwaters can be alternatives to the conventional rubble mound breakwaters as they can be designed for high stability, low wave overtopping rates and economic viability. However, fully and partly reshaped berm brekwaters require optimization of design and construction parameters which requires physical model experiments. In this study, Ordu-Giresun Airport Berm Breakwater and 4 alternative crosssections of fully and partly reshaped berm breakwaters were tested for stability and wave overtopping. Anal...
A Study on optimum layout of drainage gallery for concrete dams
Daghestani, Tameem; Yanmaz, Ali Melih; Çalamak, Melih; Department of Civil Engineering (2018)
Dams are generally massive structures retaining a large amount of water. Any failure could lead to a disaster. Therefore, keeping the dam within the required safety margins and maintaining those conditions is of the utmost importance. A gravity dam is held in place by its own weight. Uplift pressure reduces the effective weight of the dam, thus reducing its safety. Hence reducing the effect of uplift could have significant results in increasing the safety of the dam. In this study, the optimum location of t...
An Experimental Study on Compression and Shrinkage Behavior of Cement-Treated Marine Deposited Clays
Ekinci, Abdullah; Ince, Ceren; Ferreira, Pedro Miguel Vaz (2019-09-01)
Marine clay deposits are commonly found soils around the world. Owing to the high costs of material disposal and the associated environmental problems, there is a growing need to find an alternative solution to reusing unsuitable soils. In the current study, the shrinkage and compression behavior of marine deposited clays, a soil commonly found worldwide, has been studied using intact, reconstituted, and cement-treated samples. Additionally, the effect of cement inclusion was evaluated for dosages ranging f...
