不等流を遡上する波状性段波の水理実験とその数値計算

抄録

Hydraulics experiments showed that under undular bore, the maximum wave height rise was 1.4 times that under still water without flow and the wave height was up to twice the initial wave height at the downstream end. One-dimensional calculations using conventional shallow-watertheory equation unestimated the calculated wave height and over estimated the wave velocity, relative to experimental measurements. Calculations using a Boussinesq-type equation produced good agreement with experimental data.
