WebKinematic wave model. The kinematic wave model was first applied to traffic flow by Lighthill and Whitham in 1955. Their two-part paper first developed the theory of kinematic waves using the motion of water as an example. In the second half, they extended the theory to traffic on “crowded arterial roads.” WebThe kinematic wave model is widely used to simulate the overland flow (Ponce 1991, Singh 2001). Lighthill and Whitham (1955) found that the kinematic wave dominates the flood wave and can carry the main disturbance to the downstream. Henderson (1966) showed that natural flood waves behave nearly

WebThe wave property then follows directly from the equation of continuity satisfied by q and k. In view of this, these waves are described as ‘kinematic’, as distinct from the classical wave motions, which depend also on Newton’s second law of motion and are therefore called ‘dynamic’.

Webwhere H is the wave height; L is the wavelength; T is the wave period; x is the wave propagation distance, and x ¼ c t. Considering the form and equation of the wave, the wave energy consists two parts: one is from the wave ver-tical vibration and the other one is from wave impact. The influence caused by these two parts of energy is very huge.
