Considerations on Acoustic Mapping Velocimetry (AMV) Application for in-situ Measurement of Bedform Dynamics

Non-intrusive technologies for the in-situ measurement of river morphological features are increasingly popular in scientific and practice communities due to their efficient productive data acquisition. While suspended load with optical acoustic is currently an active area research, bedform dynamics has not experienced similar progress. We have successfully demonstrated through laboratory experiments that, by combining mapping image velocimetry concepts, we can characterize planar migration. The technique, labeled Acoustic Mapping Velocimetry (AMV), transferred field conditions using multiple-beam echo-sounders (MBES) producing maps. During this transfer, new questions emerged because, conditions, many morphologic targeted AMV measurements a priori known. Moreover, processing be approached several alternatives, each them characterized strength limitations. This paper assembles guidelines establishing optimal parameters acquisition maps based on analytical considerations, selecting essential velocimetry. test these MBES acquired Mississippi River.
