To determine the timing of and driving forces for sediment suspension and deposition and the effect of impoundment, three self-recording instrument packages were deployed in a section of Louisiana marsh. Two of the packages went into an impoundment and one into an adjacent open, or control, area. A data logger in the package controlled sensors to measure water level, velocity, salinity, and temperature and suspended sediment concentration. At one impoundment site and the control site, weather stations recorded wind speed and direction. This paper describes and discusses the results.
