Wave impact on a vertical baffle

We consider the wave impact against a vertical baffle or a vertical wall in close proximity to the baffle for four cases: (i) a vertical baffle at free surface; (ii) a vertical baffle in front of a wall; (iii) a vertical baffle on a deck in front of a wall; (iv) a vertical baffle on the tank bottom...
