This instrument was located very close to the bed (0.15 m) in a shallow waterway less than 2 m deep, which results in the vertical velocity's inertial subrange being reduced by the flattening of the spectra at wavenumbers of 10 cpm (0.1m scales). Strong stratification is another mechanism that shortens the inertial subrange at the lower wavenumbers. The wavenumber at which i...)
