摘要：

Debris fans debouching into the bottom of Grand Canyon create rapids and flow separation in the Colorado River. The longest recirculation zones are formed by channel constrictions of low width-to-depth ratio. Recirculation zones increase in length with increasing discharge. Sand bars form beneath recirculation zones, especially near separation and reattachment points. Reattachment bars project upstream from the reattachment point and underlie primary eddies. -from Author
