| Abstract: |
| Model tests are conducted to investigate the resistance coefficient of square-edged single-port in filling operation. On the basis of model test, an empirical formula for the resistance coefficient of square-edged single-port in filling operation is derived and technical data are provided for the design and computation of lock filling and emptying system. |
| Key words: resistance coefficient, single-port, culvert hydraulic system, lock |
