ERDC/CHL CHETN-IV-55
March 2003
d. Complex bathymetry can be recreated at scale for minimal costs.
e. Study costs are low.
Disadvantages:
a. Velocity measurements are practical only above horizontal surfaces.
b. Currents are steady in time.
c. No simulation of combined waves and currents.
d. Models of actual projects must be geometrically distorted, so some scale effects will exist.
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 or the precision flow table can be addressed to Dr. Steven A. Hughes (Voice: 601-
