2.3. Governing dimensionless parameters
The dimensional analysis applied in Heller et al. (2008) resulted in the dimensionless governing parameters with the test ranges specified in the lower part of Table 2. These parameters include the slide Froude number F¼Vs/(gh)1/2 (with the gravitational acceleration g) varied in the range 0.86rFr6.83, relative slide thickness S¼s/h (0.09rSr1.64), relative slide mass M¼ms/(rwbh2) with rw as the water density (0.11rMr10.02), relative grain diameter Dg¼dg/h
