Abstract
Monitoring bathymetry changes in shipping channels of rivers and estuaries is vital to the US economy. The standard method of sonar depth sounding from survey ships, though accurate, is slow to perform. Thus, we propose a new and innovative approach for rapid assessment of shipping channel morphology from the kinematics associated with remote sensing of the interaction of Kelvin wakes from boats with river bottoms. This program will develop a passive remote sensing methodology using imagery from airborne or possibly satellite sensors. In Phase I, we will determine the expected performance of the methodology by modeling the sensitivity of the Kelvin wave pattern to a non-uniform shipping channel. The inverse model incorporating wave dynamics associating the interaction of waves with the channel will be accomplished during Phase II and implemented in vetted algorithms.
