| Abstract: |
| 【Objective】The simplified calculation method of the depth of deepened－stilling basin was proposed to improve the design of deepened－stilling basins.【Method】The traditional calculation formula of the depth of deepened－stilling basins was simplified and the neoteric depth calculation method was established based on the momentum equation.【Result】The simplified iteration formulas of the depth of deepened－stilling basin based on the traditional calculation and the momentum equation were obtained.The two iteration methods were compared with other formulas to calculate two real cases.Results of various methods were general consistent.【Conclusion】The iteration formula of the depth of deepened－stilling basin based on the momentum equation can improve the design of the depth of deepened－stilling basin with simplified computational process and high accuracy. |
