| Abstract: | Determination of the resistance factor is pivotal in calculation of water surface profile of rapids reach.A new kind of empirical equation for determining local resistance factor was set forth based on theoretical analysis,the coefficients in which were obtained by flume test.Checked by practical rapids reach,the calculation accuracy is proved to satisfy the preliminary design of channel regulation on the whole. |
| Keywords: | channel regulation local resistance factor flume test calculation of water surface profile |
