A study was made to determine the hypothetical failure of the Dalaman Akköprü Dam by overtopping failure mechanisms. For this purpose, a 2D Hydraulic Model was constructed using HEC-RAS to determine the propagation of flood due to the failure of the dam body for this case. Froehlich equations were used to predict breaching parameters of the Akköprü Dam. After the calibration of the hydraulic model, the hydraulic model was run to determine the possible flooding of Ortaca, Dalaman, and Köyceğiz towns. Analysis of the results obtained from the modeling in the case of overtopping failure of the Akköprü Dam showed that the peak flood reaches to Ortaca and Dalaman towns in 2 hr 20 min 2 hr 50 min respectively and the significant portion of the study area highly populated, is located in the H6 hazard zone. Due to the high risk of H6 and H5 Type hazard class, structural failure may occur, city centers should be evacuated within 2 hours.


Comparison of physical and numerical dam-break simulations
Bozkuş, Zafer (Turkiye Bilimsel ve Teknik Arastirma Kurumu, 1998-01-01)
Laboratory data obtained from model studies of an existing dam under three different failure scenarios are presented. Moreover, the numerical failure simulations of the same dam were performed by employing two state-of-the-art numerical models, namely, SMPDBK and DAMBRK, both developed at the National Weather Service (NWS) in the United States. Comparison of the measured and computed results indicate that both numerical models predict peak flood elevation with somewhat reasonable accuracy. However, the resu...
Shape optimization of an excavator boom by using genetic algorithm
Uzer, Cevdet Can; Söylemez, Eres; Department of Mechanical Engineering (2008)
This study concerns with the automated structural optimization of an excavator boom. The need for this work arises due to the fact that the preparation of the CAD model, performing finite element analysis and model data evaluation are time consuming processes and require experienced man power. The previously developed software OptiBOOM, which generates a CAD model using a finite set of parameters and then performs a finite element analysis by using a commercial program has been modified. The model parameter...
Bridge scour risk assessment and countermeasure design
Yanmaz, Ali Melih (American Society of Civil Engineers (ASCE), 2012-08-01)
Statistical surveys conducted on investigation of reasons of bridge failures implied that the majority of bridges have failed because of excessive scouring at infrastructural elements. A bridge crossing an alluvial river should therefore be designed properly with special reference to possibility of this action at piers and abutments. On construction of a bridge, its scour criticality should be examined regularly throughout the service life spans to take necessary actions promptly. The Federal Highway Admini...
Stochastic modeling of accident risks associated with an underground coal mine in Turkey
Sari, Mehmet; Kestel, Sevtap Ayşe; Karpuz, Celal; Duzgun, H. Sebnem B. (2009-01-01)
In this study, a methodology is proposed towards development of all uncertainty model that includes randomness in the occurrence of days-lost accidents in a coal mine. The accident/injury data consists of 1390 days-lost accident cases recorded at GLI-Tuncbilek underground lignite mine from January 1994 to December 2002. In the first step of proposed methodology, the frequency and the severity of the accidents have been modeled statistically by fitting appropriate distributions. The test done by BestFit soft...
Seismic testing of a scaled roller-compacted-concrete gravity dam
Gharibdoust, Ali; Binici, Barış; Department of Civil Engineering (2016)
Within the last half-century, seismic response analysis of concrete gravity dams has been extensively studied. Studies reveal that two types of failure modes prevail in the form of dam body cracking or base slide. The literature lacks the conditions that clearly differentiate the two failure types. In this context a state of the art single degree of freedom pseudo-dynamic testing was developed to assess the gravity dam response on smooth foundation interface. Three different hazard levels of earthquake name...
