MEASUREMENTS OF RUNUP ON SEAWALLS OF WAVES FROM SIMULATED UNDERWATER EXPLOSIONS NEAR SHORE.

Abstract

Laboratory data are presented for the runup on plane-faced seawalls of the leading waves from impulsive disturbances simulating underwater explosions. The tests covered walls with faces vertical and sloping 4:1 and 2:1 from horizontal, with foreshore slopes of 1:14 and 1:20. The tests covered two general classes of wave trains--specifically, trains with a leading trough (as produced by explosions in relatively deep water) and trains with a leading crest (as produced by explosions in relatively shallow water). The more important data pertain to the latter class, since significantly large explosions not far from shore are of the shallow-water type. A noteworthy aspect of the tests was the limited dispersion of the wave trains, resulting from the relatively short propagation distance and the large radius of the area covered by the disturbance, relative to the depth.
