Experimental study of small rivers mouth sections profiles stability using a hydrostatic depth gauge

The features of using a hydrostatic depth gauge to study the deformation and stability of profiles of mouth sections of small rivers are considered. Instruments and methods for determining the depth in river channels are analyzed. The method of performing experiments is described, as well as the main characteristics of the equipment used. The results of expeditionary research in the mouths of the Chernaya, Belbek, and Kacha rivers (Sevastopol) obtained using these technical means are described. The use of a hydrostatic meter allows you to quickly obtain information about the depth profile, which is necessary when calculating water flow and modeling the hydrological regime of river mouths.
