In this study, the wave pressure on components of Stilling Wave Basin (SWB) is investigated by analyzing the physical model experiment data of wave pressures for various hydrodynamic conditions. SWB is a structure that can be used for optimizing the crest height to achieve lower overtopping conditions especially in urban areas. The experiments are based on assessing the performance of SWB on a vertical seawall for which limited research exists. Wave pressure data on the seaward storm walls (both rows) and the landward storm wall behind a promanade is analyzed as individual components as well as the whole SWB structure to determine the magnitude and type of wave pressure. The comparison of wave pressure can be used to determine the effect of SWB configuration on the wave loads acting on each component. The results show that additional superstructures on the seaside of the SWB, the pressure measurement of the landward storm wall decreases remarkably. Storm wall with gaps on the seaside causes more pressure in front of the storm wall. Placing bullnoses as a superstructure on top of the storm wall causes pressure increase on seaward storm wall structure but decrease on the landward structures. The empirical formulations of Goda (2010) including maximum pressures usually underpredict the pressures. However, the scatter is much higher for the maximum pressure dataset.

Investigation of flow and scour around head of a vertical wall breakwater Karakaş, Kadir; Baykal, Cüneyt; Department of Civil Engineering (2019) In this study, wave induced hydrodynamic and morphodynamic processes around the head of a vertical wall breakwater are investigated by numerical and physical modeling. An open source computational fluid dynamics code was used to investigate the flow around the head of structure. The code solves incompressible Reynolds-Averaged Navier-Stokes equations with a k-omega turbulence closure. For investigating flow and scour around the structure, small-scale physical model tests were carried out in the random wave ...
Design weight of armour stone considering the effect of extreme waves Ozbahceci, Berguzar Oztunali; Ergin, Ayşen (Elsevier BV, 2008-3) In this study, waves with the heights higher than H-1/3 in an irregular wave train are called as extreme waves and defined with the help of extreme wave parameter, alpha(extreme). In order to see the effect of extreme waves on the design weight of armour stone, stability analysis is carried out based on the hydraulic model test results. The test results of high alpha(extreme) cases (HE) and low alpha(extreme) cases (LE) are compared with currently used van der Meer's formulae with permeability factor P = 0....
Analytical solutions for evolution and runup of longwaves over a sloping beach Ceylan, Nihal; Kanoğlu, Utku; Department of Engineering Sciences (2019) The initial value problem of the linear evolution and runup of long waves on a plane beach is analyzed analytically. The shallow water-wave equations are solved by integral transform and eigenvalue expansion methodologies. The results from linear solutions are compared with the solution of the nonlinear shallow water-wave equations confirming the runup invariance, i.e. nonlinear and linear theories produce same maximum runup. Then, existing analytical nonlinear solution for shoreline motion is implemented f...
Analysis of RC walls with a mixed formulation frame finite element Sarıtaş, Afşin (2013-10-01) This paper presents a mixed formulation frame element with the assumptions of the Timoshenko shear beam theory for displacement field and that accounts for interaction between shear and normal stress at material level. Nonlinear response of the element is obtained by integration of section response, which in turn is obtained by integration of material response. Satisfaction of transverse equilibrium equations at section includes the interaction between concrete and transverse reinforcing steel. A 3d plastic...
Assessment of flood hazards due to overtopping and piping in Dalaman Akköprü Dam, employing both shallow water flow and diffusive wave equations Yilmaz, Kutay; Darama, Yakup; Oruc, Yunus; Melek, Abiddin Berhan (2023-01-01) This study was carried out to determine flood propagation using shallow water equations (SWEs) and diffusive wave equations (DWEs) to reveal how the flood modeling results differ in terms of flow depth, flow velocity, and hazard level. The solution methods were tested based on the hypothetical failure of the Dalaman Akköprü Dam resulting from two failure mechanisms: overtopping (OT) and piping (PP). A 2D hydraulic model was constructed using HEC-RAS to determine the propagation of flood waves due to the fai...
