Dam break analyses for disaster management

Numerical failure simulations of Kestel dam were performed under different scenarios. The numerical model employed was developed by Fread, D.L., and called DAMBRK. In the simulations, it was assumed that a breaching started, within the dam body soon after the maximum possible flood hydrograph entered the dam reservoir and caused the water to spill over the dam crest due to insufficient capacity of the spillway. Peak flood discharges, peak flood elevations and flood arrival times at preselected six cross-sections downstream of the dam were determined. Regions affected most adversely were found to be those closest to the dam site.

Pre-event dam failure analyses for emergency management
Bozkuş, Zafer (2001-12-01)
Simultaneous dam-break analyses of two dams, namely the Nilüfer and Doǧanci dams, due to a breach in their bodies, were performed under various hydraulic conditions. Both of the dams are located in the same river branch of the Nilufer Basin in the province of Bursa in Turkey. The main purpose of the study was to see the negative effects of such failure on the city of Bursa, which is located downstream of the dams, as well as to make available the results of the study to the relevant public officials for the...
Flow and turbulence structure around abutments with sloped sidewalls
Köken, Mete (American Society of Civil Engineers (ASCE), 2014-01-01)
Results of eddy-resolving numerical simulations are used to investigate flow and turbulence structure around an isolated abutment with sloped sidewalls at conditions corresponding to the start (flatbed) and the end (equilibrium bathymetry) of the scour process. Besides cases where the abutment is not protected against scour using riprap, the paper considers cases where a riprap apron of constant width is present around the base of the abutment at the start of the scour process. The paper also discusses the ...
Multigrid methods for optimal control problems governed by convection-diffusion equations
Arslantaş, Özgün Murat; Karasözen, Bülent; Yücel, Hamdullah; Department of Scientific Computing (2015)
Linear-quadratic optimal control problems governed by partial differential equations proved themselves important through their use in many real life applications. In order to solve the large scale linear system of equations that results from optimality conditions of the optimization problem, efficient solvers are required. For this purpose, multigrid methods, with an ordering technique to deal with the dominating convection, can be good candidates. This thesis investigates an application of the multigrid me...

The probability density estimation of the number of software failures in the event of clustering or clumping of the software failures is the subject of this paper. A discrete compound Poisson (CP) prediction model, as opposed to a Poisson (P) process, is proposed for the random variable (rv) X(rem), which is the remaining number of software failures. The compounding distributions, which are assumed to govern the failure sizes at Poisson arrivals, are respectively taken to be geometric when failures are fo...
Discharge prediction in flow measurement flumes with different downstream transition slopes
Göğüş, Mustafa; Atalay, Ahmet E.; Khatib, Jumana I. (2016-03-01)
Experimental testing of 9 different rectangular compound cross-section flow measurement flumes with different downstream slopes was conducted to yield the coefficient of discharge and the approach velocity coefficient. The aim of the experimental research was the determination of stage-discharge relationship in compound cross-section flow measurement flumes with different downstream slopes. One empirical predictive model for each of the coefficient of discharge and the approach velocity coefficient for the ...
