As the same trend can also be observed for the peak slamming forces per unit area, which are shown in the right graph of Fig. 11, a similar power-law function can be defined here: (29) F m a x = k f ρ v I 1 ∕ 3 ln c where F m a x is the maximum value of the impact force per unit area and the coefficient k f depends on the aeration level in ...
The impulse (F × time) is not a force (N), it is an integral of force over time. The impact is a force (N). Impact deals with force and of course force deals with acceleration. The impact force is usually extremely short. The impact force has the same unit as the force (F = m ⋅ a ). Impulse deals with momentum, which in turn deals with velocity.

The impact pressure (load per unit area) in a rapidly moving dry-snow avalanche is typically assumed to vary with the density and velocity as ∼ ρ f ū 2 (SLF, 1990, Norem, 1990). This implies a relatively small variation of C D with velocity if the area affected by the pressure scales with Bh, independent of the velocity.
wave impact force could be 2.5 times the drag force. Goda [3] introduced an additional force term to be added to the original Morison equation to account for the additional slamming load induced by the plunging breaker. (4) = 0.5 * (5) is the curling factor; a ratio of breaking wave impact length on structure over the breaking wave height.

Lateral impact, sometimes called lineal impact, is force per unit width and shows the volumetric distribution pattern and the evenness of the impact across the spray. Lateral impact is usually expressed in lb./in. or kg/cm. It provides a relative indication of cleaning effectiveness; Specific impact is the total impact force divided by a unit area.
Realize that the kinetic energy (measured in ft-lbs) at impact is very different from the force of the impact (measured in lbs). The KE is easy to figure: it's equal to the initial gravitational potential energy = mgh. So both (1) and (2) have the same energy at impact = 2*8 = 4*4 = 16 ft-lbs. (Note that they don't hit with the same momentum (mv); …

To date, the impact process induced by plunging breakers has not been fully deciphered. Plunging breakers propagate with spatial-temporal variations both in the wave geometry and the wave kinematics. Thus the relative distance between the break point and the cylinder has an influence on breaking wave forces.
