In the study the effect of collars on scour for spill-through abutments under clear-water conditions was investigated. Total of 70 experiments were conducted. Two abutments were placed on the opposite sides of a straight rectangular channel. Collars with different widths were placed at different depths around these abutments and reduction on scour was investigated for each case. Using different abutment lengths allowed investigation of collars at different contraction ratios and hence optimum collar configuration and depth was defined for abutments with various contraction ratios. It is concluded that collars are effective in reducing scour and protecting spill-through abutments against scour.

Time evolution of the flow characteristics around bridge abutments during scouring process Yıldız, Burhan; Köken, Mete; Göğüş, Mustafa; Department of Civil Engineering (2014) This study involves numerical and experimental investigation of the velocity field and the time evolution of the scour pattern forming around bridge abutments. The experimental part of the study includes velocity field recordings by using an ADV device and eroded bed bathymetry measurements by an ultrasonic ranging system. Using the ADV measurements; the velocity components, the upstream part of the primary vortex and the change of downstream recirculation region dimensions by the change in abutment length,...
Optimization of coagulation-flocculation process for treatment of a colloidal suspension containing dolomite/clay/borax ÇIRAK, MUSTAFA; Hoşten, Çetin (2017-02-10) This study statistically investigated the turbidity removal of a dolomite/clay/borax-containing colloidal suspension that had a high degree of stability. During the destabilization experiments, the mixing intensity, the dosage of the coagulant and the flocculant was tested at fixed pH 9.40 due to the buffering property of dissolved borax. Then, the performance of the coagulation/flocculation process was evaluated with Response Surface Methodology (RSM) by using Box-Behnken Design. For the collected experime...
Scour at the rear side of rubble mound revetments Yıldırım, Mehmet Emre; Baykal, Cüneyt; Department of Civil Engineering (2021-8-17) In this study, an examination of the scour at the rear side of rubble mound revetments resulting from wave overtopping was performed. The effects of backfill materials, backfill height, and wave properties on the process were investigated through physical model experiments. One of the main findings of the study is that as the storm duration increases, the maximum scour depth eventually reaches an equilibrium state. Also, as the overtopping discharge increases, the scour depth occurs deeper. Estimation of ge...
Improving the trajectory tracking performance of autonomous orchard vehicles using wheel slip compensation BAYAR, Gokhan; Bergerman, Marcel; Konukseven, Erhan İlhan; Koku, Ahmet Buğra (2016-06-01) In this paper, the effects of wheel slip estimation and compensation of trajectory tracking for orchard applications were investigated. A slippage estimator was developed and adapted into a car-like robot model. Steering and velocity commands were generated using a model-based control approach. The whole system was implemented and tested on an autonomous orchard vehicle that has steerable front wheels and actuated rear wheels. A high accuracy positioning system was used to estimate the longitudinal and late...
Numerical simulation of scour and backfilling processes around a circular pile in waves Baykal, Cüneyt; Fuhrman, D. R.; Jacobsen, N. G.; Fredsoe, J. (2017-04-01) This study continues the investigation of flow and scour around a vertical pile, reported by Roulund et al. (2005). Flow and scour/backfilling around a vertical pile exposed to waves are investigated by using a three-dimensional numerical model based on incompressible Reynolds averaged Navier-Stokes equations. The model incorporates (1) k-omega turbulence closure, (2) vortex shedding processes, (3) sediment transport (both bed and suspended load), as well as (4) bed morphology. The numerical simulations are...
