Impulsive Force on Walls Due to the Collision of a Bore

An analytical procedure is developed for predicting the time-dependent impulsive force on vertical walls due to the collision of a bore. The impulsive force is estimated by using Cumberbatch's theory which treats the problem of a water wedge striking a wall. The comparison of the theoretical and experimental results shows that the present theory well estimates the total impulsive force and maximum impulsive pressure when the depth of water in the downstream region of the bore is sufficiently small compared with the height of the bore front.
