"Following work by
Irribarren (1938, 1950), comprehensive investigations
were made by Hudson (1953, 1959, 1961) at the U.S. Army
Corps of Engineer Waterways Experiment Station (WES) and
a formula was developed to determine the stability of
armor units on rubble structures. The stability formula,
based on the results of extensive small-scale model
testing and some preliminary verification by large-scale
model testing, is known by Hudson Formula". Shore
Protection Manual, 1984.
