Summary/Abstract

Elevations of a Mississippi River side channel were captured using several methods in 2007 and 2008. Water depths were recorded using boat-mounted GPS depth sounders. Exposed sandbars were mapped with GPS units and laser levels. All measurements were adjusted to daily river elevations from Price Landing gage station. The 2007 and 2008 surfaces were subtracted to identify locations where sediment had been eroded or deposited over time.
