Abstract

ABSTRACT Yamada, F., Tateyama, R., Tsujimoto, G., Suenaga, S., Long, B. and Pilot, C. 2013. Dynamic monitoring of physical models beach morphology and sediment transport using X-ray CT scanning technique A medical X-ray CT scanner was applied to dynamic measurements of beach profile changes, sedimentary structures, and sediment transport processes during wave actions in the laboratory experiments. An acrylic flume 7 m long and with an inner rectangular cross-section of 0.3 m × 0.3 m passes through the mobile gantry of a medical X-ray CT-scanner. The experiments were conducted at the Institut National de la Recherche Scientifique (INRS) at the University of Quebec from August 18 to October 16, 2011. The flume was filled with Ottawa sand (d50 = 0.147 mm) with uniform slope of 1/15. The water depth over a horizontal bed is 0.2 m. Regular waves were used with wave height of 4.0 cm and wave period of 0.7 s. In order to measure the cross-shore evolutions both of beach profiles and sediment transport process, th...
