Abstract : This study examines the feasibility of obtaining spatial and temporal suspended sediment concentrations in the laboratory through the use of high-speed filming and image analysis. A series of filming experiments was conducted in a laboratory wave flume to investigate filming parameters and to determine optimum conditions for filming high quality footage of sediment transport. A relatively simple procedure is used to map the contours of light intensity returned from digitized 16mm film images and to relate these contours to the concentration of suspended sediment. Improvement of this nonintrusive measurement technique could provide researchers with the capability to perform quantitative measurements of sediment transport at the microscale. Keywords: Image analysis, Suspended sediment, Sediment concentration.
