河床波の発生・発達過程に関する実験的研究 (2)

Abstract

Experimental studies are made on the process of developments of sand waves. Wave heightand wave length of individual sand wave are measured from photographs of plan views of sandwaves which are taken every half a minute with a camera fixed over the channel.The process of increment of wave length and wave height is investigated in detail to find out thedifference in the process of developments between ripples and dunes.Models of developing process are constituted for ripples and dunes respectively to obtain therelating equations between wave length and wave height.The equations are shown to be in good agreement with experimental results.
