Text: When studying statistical characteristics of sand waves, some authors (18) investigated the nature of the lower escarpment angles distribution and did not find the influence of the flow hydraulic characteristics on its value. The above works do not generalize the **data** obtained, do not conduct a quantitative and qualitative analysis of the works devoted to the ridges' lower escarpment, and the conclusions drawn are local in nature.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
