1. What would be the speed of a tsunami across the open ocean above an abyssal plain(深海平原)? (Assume the average depth is 5.5 km.)
2. A wave train is propagating toward the coastline over beach with slope of 1/20, the depth contours is straight and parallel. The deep water wave height is 1 m and the wave period is 5 s.
(a) If the wave propagates normally toward to the coastline, what is the breaking depth and breaking wave height?
(b) If the wave propagates obliquely(斜的) toward the coastline with wave direction angle 45º in deep water, what is the breaking depth and breaking wave height?
