摘要：
This paper shows an approach that is useful for evaluating the resistance to flows in narrow open channels. A series of experiments were first carried out in a smooth, rectangular, open channel for which the aspect ratio varied from 0.12 to 1.53. Experimental data collected were then used to validate a resistance formula that was proposed previously by modifying Prandtl's friction law. DOI: 10.1061/(ASCE)HY.1943-7900.0000582.
