Hydrodynamic vs kinematic wave

WebKinematic Wave Model proportional to the square of the mean velocity V = Q/S 7 = fpPV2, where f is a friction coefficient, p the density of water, and P the wetted perimeter (see Figures 1 and 2). Following Lighthill and Whitham, we balance the resistance r with the x-component F, of gravity which, for small reach slope i, can be written as In gravity and pressure driven fluid dynamical and geophysical mass flows such as ocean waves, avalanches, debris flows, mud flows, flash floods, etc., kinematic waves are important mathematical tools to understand the basic features of the associated wave phenomena. These waves are also applied to model the motion of highway traffic flows. In these flows, mass and momentum equations can be combined to yield a kinematic wave equ…
