Back Acoustical Characterization of the Riverine Environment

Define and describe the acoustical characteristics of different riverine environments (e.g. braided (shallow, strong currents, gravelly bed), meandering (deep, weak currents, muddy bed)) using simple acoustic instrumentation, and correlate these acoustical characteristics to traditional riverine observational parameters (e.g. current profiles, geological descriptors).
Develop an acoustic propagation model to investigate the effect of the environment on the measured acoustic parameters, and validate the acoustic model with in situ field observations.
Through measurements and modeling, investigate the sensitivity of these acoustical-environmental correlations to frequency, and examine the temporal and spatial scales of variability in the riverine environment and its impact on signal coherence as a function of time, frequency and range.
