Abstract

PURPOSE: The Coastal and Hydraulics Engineering Technical Note (CHETN) herein describes a method for estimating the percentage of sand-sized material placed in suspension by breaking waves and carried by a cross-channel current to either fall into a navigation channel or travel across it. Required inputs are channel width and depth, depth in the vicinity of the channel, depth-averaged current velocity perpendicular to the channel, and sediment fall speed. The procedure is applicable to inlet entrances that experience breaking waves. The percentage of material deposited into or passing a channel is an input to the channel infilling model described in Kraus and Larson (2001).
