Quality and durability assessments of the armourstones for two rubble mound breakwaters (Mersin, Turkey)

Ertas, B.
Topal, Tamer
Due to economic reasons, natural stones (armourstones) of various sizes and qualities are very frequently used for the constructions of the breakwaters to protect coastal engineering structures from wave actions. Deterioration of the armourstones with time in the form of abrasion and disintegration may end up with the damage of the structures. Therefore, it is necessary to investigate the long-term performance and quality of the armourstones, which should be sound and durable. Mersin and Kumkuyu harbours were constructed using four different limestones obtained from two quarries. The limestones have different characters and site performances. In this study, the material and mass properties of the limestones taken from the quarries with known site performances as armourstones are investigated. The site performances and durability of the limestones are compared with the field measurements and laboratory works. Thus, the information obtained is used to assess long-term durability of the armourstones. The long-term performance of the Degirmencayi and Tirtar upper level limestones are observed to be good whereas it is rather poor for the Tirtar middle and lower level limestones. Comparison between the predicted and observed durabilities of the armourstones indicated that CIRIA/CUR, RDI(d), RERS, and wet to dry strength ratio give better results based on their field performances. However, the prediction of the durability of the limestones is poor in case RDIs, average pore diameter, and saturation coefficient are used.


A model for the conservation of geological remains as documents
Sol, Ayhan (Springer Science and Business Media LLC, 1999-01-01)
Geological remains are conserved mainly either together with living beings for the sake of the integrity of nature or for their economical or aesthetic value. However, they also have scientific value for the geologist to reconstruct the earth's past. For this reason we propose a model which is an application of marginal utility theory in economics and takes into account the informational utility of geological remains. Informational utility of geological remains ranges over their geological significance whic...
Environmental geological and geotechnical investigations related to the potential use of Ankara clay as a compacted landfill liner material, Turkey
Met, İlker; Akgün, Haluk; Türkmenoğlu, Asuman Günal (Springer Science and Business Media LLC, 2005-01-01)
Clay-bearing Upper Pliocene red clastics and Quaternary alluvial deposits occupy the Ankara basin. The clayey levels of the Upper Pliocene deposits, referred to as Ankara clay, is considered as a source for compacted clay liners due to their low coefficients of permeability and widespread distributions throughout Ankara. This study investigates the geological, geotechnical and mineralogical properties of the founding clayey soils at two sites of the Ankara region. The geotechnical index properties along wit...
Flood forecasting and analysis within the Ulus Basin, Turkey, using geographic information systems
Usul, Nurunnisa; Turan, Burak (Springer Science and Business Media LLC, 2006-10-01)
Floods have been the most severe natural disasters in the West Black Sea Region of Turkey for many years; therefore Ulus Basin is selected as a study area for a thorough hydrologic flood analysis. The lack of embankments around the Ulus River and careless changes to the riverbed made by villagers, resulted in major flood events in the basin, causing significant damage in the area. In this study, the hydrodynamic characteristics of the basin and the riverbed are determined by calibrating the hydraulic module...
Environmental Discourse of Architecture
Basa, İnci (Informa UK Limited, 2009-01-01)
This study attempts to examine the environmental discourse of architecture. The attempt to constitute a linguistic framework for the environmental discourse requires a critical understanding of the interrelationship among the following concerns: a) discourse as a ‘system of statements’ that prescribes the ‘theoretical formation’ of an object, b) architecture as a field in which several discourses (professional, technological, social, representational, theoretical, etc.) operate around their specific objects...
Environmental geological investigations at the Van open dump site, southeastern Turkey
Akgün, Haluk (Springer Science and Business Media LLC, 2000-04-01)
This study evaluates the geological, hydrogeological and hydrological conditions at the I waste dump site of the Van municipality in eastern Anatolia, Turkey. A geological map and a three-dimensional view of the project site have prepared. All lithological units exposed at and near the dump site have been determined and their boundary relationships identified. Drainage basin characteristics of the dump site along with the water bearing properties of different lithological units have been assessed. For the r...
