Straight drop structures.

Variables from the figure

  • yc — Critical depth
  • h0 — Drop from crest to stilling basin floor
  • h — Vertical drop between the approach and tailwater channels
  • y1 — Pool depth under the nappe
  • y2 — Depth of flow at the tow of the nappe or the beginning of the hydraulic jump
  • y3 — Tailwater depth sequent to y2
  • L1 — Distance from the headwall to the point where the surface of the upper nappe strikes the stilling basin floor
  • L2 — Distance from the upstream face of the floor blocks to the end of the stilling basin
  • L3 — distance from the upstream face of the floor blocks to the end of the stilling basin
  • LB — Stilling basin length
