water depth. A formula was also given for estimating the wave momentum flux parameter for
solitary waves. Example calculations are provided for both wave types.
The wave momentum flux parameter is useful for developing improved semiempirical formulas to
describe such wave/structure processes as runup, overtopping, reflection, transmission, and armor
stability. The first application of the parameter has been revised design guidance for irregular wave
runup on smooth, impermeable plane slopes as detailed in CHETN-III-68 (Hughes 2003).
ADDITIONAL INFORMATION: This CHETN is a product of the Scour at Inlet Structures Work
Unit of the Coastal Inlets Research Program (CIRP) being conducted at the U.S. Army Engineer
Research and Development Center, Coastal and Hydraulics Laboratory. Questions about this
technical note can be addressed to Dr. Steven A. Hughes (Voice: 601-634-2026, Fax: 601-634-
