Breakdown of a shallow water equation
WebEquations (5.23), (5.27), and (5.28) are difficult to solve due to the sines and cosines of latitude which enter. A useful approximation is to treat a region of the earth’s surface as WebThe shallow water equations model the propagation of disturbances in water and other incompressible fluids. The underlying assumption is that the depth of the fluid is small compared to the wave length of the disturbance. For example, we do not ordinary think of the Indian Ocean as being shallow. The depth is two or three kilometers.
