     Spatial differentiation and dynamic changes in micro-geomorphology were studied based on acoustic data interpretation from a wide range (3 200 km2) of the Huanghe (Yellow) River delta (HRD). […] There were seven typical micro-geomorphologic features in the shallow and surface areas of the HRD, including buried ancient channels, stratigraphic disturbances, scour troughs, sand waves, pits, erosional remnants, and sand spots. […] From the perspective of acoustic profile interpretations, the scale, range, and spatial locations of the micro-geomorphology in the HRD revealed seasonal variation characteristics, and the spatial distributions displayed significant regional differentiation characteristics.
