Probabilistic snow cover and ensemble streamflow estimations in the Upper Euphrates Basin
(Veda, Slovak Acad Sciences, 2019)Predicting snow cover dynamics and relevant streamflow due to snowmelt is a challenging issue in mountainous basins. Spatio-temporal variations of snow extent can be analyzed using probabilistic snow cover maps derived ... -
Real-Time Flood Control by Tree-Based Model Predictive Control Including Forecast Uncertainty: A Case Study Reservoir in Turkey
(MDPI, 2018)Optimal control of reservoirs is a challenging task due to conflicting objectives, complex system structure, and uncertainties in the system. Real time control decisions suffer from streamflow forecast uncertainty. This ... -
Reassessment of the flood damage at a river diversion hydropower plant site: lessons learned from a case study
(Springer, 2017)Despite the accumulated vast theoretical and practical knowledge on the flood-related topics, the lack of precautions taken against the natural disasters keeps causing fatality and property damage. In this study, a recent ... -
Repeated Creep Behavior of Polypropylene Fiber-Reinforced Bituminous Mixtures
(Asce-Amer Soc Civil Engineers, 2009)In recent years, research has been devoted to the control of permanent deformations in flexible pavements. In order to prevent rutting, fatigue, and low-temperature cracking, different types of polymer modifiers have been ... -
Response of Seismic-Isolated Bridges in Relation to Intensity Measures of Ordinary and Pulselike Ground Motions
(Asce-Amer Soc Civil Engineers, 2013)This study concentrates on the efficiency of numerous ground motion intensity measures (IMs) to be used in estimating the response of seismic-isolated bridges (SIBs). Efficiency of commonly used IMs was investigated through ... -
Retained properties of concrete exposed to high temperatures: Size effect
(John Wiley & Sons LTD, 2009)Concrete as a construction material is likely exposed to high temperatures during fire. The retained properties of concrete after such exposures are still of great importance in terms of the serviceability of structures. ... -
Retrofit of non-seismically designed beam-column joints by post-tensioned superelastic shape memory alloy bars
(Springer, 2018)A series of tests on three full-scale substandard exterior beam-column joints were performed to investigate the efficiency of the proposed retrofit configuration, which is the use of externally applied post-tensioned shape ... -
Rutting Analysis of 100 mm Diameter Polypropylene Modified Asphalt Specimens Using Gyratory and Marshall Compactors
(University Fed Sao Carlos, Dept Engenharia Materials, 2013)Compaction technique used in Marshall design does not model the process of actual rolling procedures on site exactly. Carrying out laboratory compaction of dense bituminous mixtures with Superpave gyratory compactors is a ... -
Rutting Prediction of Asphalt Mixtures Modified by Polypropylene Fibers via Repeated Creep Testing by Utilising Genetic Programming
(University Fed Sao Carlos, Dept Engenharia Materials, 2013)A novel application of genetic programming (GP) for modelling and presenting closed form solutions to the rutting prediction for polypropylene (PP) modified asphalt mixtures is investigated. Various PP fibers have been ... -
Scaling Legitimacy for Design of Lead Rubber Bearing Isolated Structures Using a Bounding Analysis
(Earthquake Engineering Research Inst, 2016)In dynamic analyses, although there is no limitation for scale factors, the customary values vary from 0.25 to 4. However, these values are based on subjective judgments rather than a quantitative evaluation. This study ... -
Seismic repair of captive-column damage with CFRPs in substandard RC frames
(Techno-Press, 2017)The effectiveness of the repair scheme for the damaged captive-columns with CFRPs (Carbon Fiber Reinforced Polymer) was investigated in terms of response quantities such as strength, ductility, dissipated energy and stiffness ... -
Seismic vulnerability assessment criteria for RC ordinary highway bridges in Turkey
(Techno-Press, 2012)One of the most important and challenging steps in seismic vulnerability and performance assessment of highway bridges is the determination of the bridge component damage parameters and their corresponding limit states. ... -
Sepiolite as an alternative liner material in municipal solid waste landfills
(Asce-Amer Soc Civil Engineers, 2008)Compacted clay has traditionally been used as a lining material in municipal solid waste landfills. However, natural clays may not always provide good contaminant sorption properties. One alternative material that is ... -
