Experimental apparatus and methods for scour of seams between tubes of punctured geotube dam

To simulate the scour of punctured geotube dam along the seams between tubes under wave action, a set of experimental study apparatus is designed. The apparatus mainly includes wave generator, pipeline, sand box and information collecting device. The related methods are put forward, including experimental materials and processes. Finally, the effectiveness of the apparatus and methods is validated, and it is verified that the scouring process of punctured geotube dam in different waves can be simulated by the apparatus.
