Some equations for the length of the hydraulic jump and the roller are resumed in Table 3. Values of the relative energy dissipation ratio E 2 E 1 relative length of hydraulic jump L j Y 2 and relative roller length L r Y for different blocks in this study were found in. Y Fr Fr Fr y 11 11 123 28 16 xxxx Submerged Jump If the downstream water level is high enough sequent depth y 2 the jump might be submerged.
The depth of submergence y 3 is then a crucial unknown.
