In our last monograph "A new paradigm of formation of accumulative relief in shallow areas of oceans and seas" (Ukrainian), the exogenous theory of the formation of underwater and above-water accumulative bottom relief forms is called into question. Look at the photo of the strait between the Sea of Azov and the Black Sea. In the Sea of Azov, the level is higher (two rivers flow into it) and storm surges often occur both from the north and from the south. Very often current velocities exceed 100 cm/s. Based on the exogenous theory, there should not be sandy islands (spits) in the strait. They exist contrary to the exogenous theory of the formation of the bottom relief of shallow waters. The storm theory of bottom relief formation cannot explain why the accumulative bottom relief forms are stable for hundreds of years. This can be seen by looking at the bathymetric maps of the Sea of Azov made 200 years later. Please comment and ask questions.
