In the present research, hydrodynamic behavior of free surface vortices including surface displacement of the vortex core as a function of the vortex stability, relationship between the intake hydraulic parameters and vortex strength and characteristics of the vortex vertical stretching as a function of the intake hydraulic parameters were experimentally investigated in a horizontal intake. Relationship between the vortex-induced air and vortex strength was also evaluated and compared with the previous researches. In this regard, by defining a non-dimensional parameter as intake number, relationships between intake hydraulic parameters and other investigated dynamic aspects of free-surface vortices were discussed.
