Seawalls
are the most widely adopted coastal protection measure. The design of an
efficient seawall should be such that overtopping is minimized even during
coastal flooding and extreme events by maintaining its crest elevation lower. This may possibly be achieved
by reshaping the front shape of the structure in such a way that it offers
maximum resistance to the flow or enhances the dissipation of incident wave
energy. With this background, an experimental study on the measurement of
run-up and dynamic pressures over three different types of curved front face
seawall models along with a vertical seawall was carried out. The measured
parameters for the three types of curved seawalls are compared with that for a
vertical seawall. All the tests were carried out with the models rigidly fixed
over a bed slope of 1 in 30 in a wave flume and subjected to the action of
Cnoidal waves. The dynamic pressure distributions measured along the surface
and the run-up over the models are reported in a dimensionless form as a
function of relative water depth and ursell parameter. The details of the test
facility, models, experimental program, results and analysis are presented and
discussed in this paper.
