Design stilling basins, impact basins, and energy dissipation structures using FHWA HEC-14 and USBR methodology. Calculate basin dimensions, sequent depth, and energy dissipation.
| Type | Froude | L/y2 |
|---|---|---|
| Type I | < 2.5 | 4 |
| Type II | > 4.5 (high V) | 4.3 |
| Type III | 4.5 - 17 | 2.8 |
| Type IV | 2.5 - 4.5 | 6 |
Impact basins are effective for small discharges and high velocities where space is limited.
Select a dissipator type and enter flow parameters to design the basin.
