| Abstract: |
| Extensive hydraulic model tests were conducted to investigate the resistance coefficient of lock manifold single-port under filling operation and emptying operation. The relationship between single-port resistance coefficient and its related factors (geometric parameter, culvert-to-port velocity ratio, and Reynolds number of culvert flow)was studied,and empirical formulas for single-port resistance coefficient were derived. |
