A large set of data on natural environment conditions at the continental margin of the Russian sector of the Black sea was collected over the last decades. Studies revealed the diversity and heterogeneity of morphological structures on many areas of different size. The relief of the Earth surface is formed by endogenous and exogenous processes. They are most active in the transition zone between land and sea. Researchers pay particular attention to investigation of the Black Sea coast. This area is the most vulnerable to the effects of natural phenomena. Results of investigation of bottom relief and land topography in the region of the Hotetsay river mouth are presented in this paper. This study is based on single-beam bathymetric data collected onboard the MNIS "Ashamba". Main tasks of this work included study of bottom and land topography of the study area as well as its origin and evolution and revealing of possible evidence of catastrophic floods. This work is a continuation of the previous studies carried out in the Golubaya Bay and on the continental margin between Divnomorskoe and Betta villages. Analysis of the obtained results allowed to compile a bathymetric and geomorphological map and to determine the significant impact of neotectonic processes on formation of morphostructures in the study area.
