3D Reconstruction of Simulated Bridge Pier Local Scour Using Green Laser and HydroLite Sonar.

Unknown Date (has links)
Scour is the process of sediment erosion around bridge piers and abutments due to natural and man-made hydraulic activities. Excessive scour is a critical problem that is typically handled by enforcing design requirements that make the submerged structures more resilient. The purpose of this research is to demonstrate the feasibilities of the Optical- Based Green Laser Scanner and HydroLite Sonar in a laboratory setting to capture the 3D profile of simulated local scour holes. The Green Laser had successfully reconstructed a 3D point-cloud imaging of scour profiles under both dry and clear water conditions. The derived scour topography after applying water refraction correction was compared with the simulated scour hole, and was within 1% of the design dimensions. The elevations at the top and bottom surfaces of the 6.5-inch scour hole were -46.6 and -53.11 inches from the reference line at the origin (0,0,0) of the laser scanner. The HydroLite Sonar recorded hydrographical survey points of the scour’s interior surface. The survey points were then processed using MATLAB to obtain a 3D mesh triangulation. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

Sediment transport effects on drop structure scour

Nordby, Brett Gene, 1959- January 1989 (has links)
In 1983, Laursen and Flick (1) proposed an equation to predict the depth of scour at the toe of a sloping sill. The equation was developed for use with clear-water only since their experiments did not fully investigate the effect of sediment transport. Their report also left open the question of the possible ramifications of sediment transport on the depth of a scour hole. This thesis is an exploratory investigation of the effect of the sediment transport phenomenon on the depth of a scour hole. It will discuss and compare both the clear-water and sediment transport conditions and to explore if the sediment transport rates to be expected in most streams would have a substantial effect on the scour at the toe of a sloping sill.
