Abstract: This paper has reviewed the approaches to estimate the roughness of flexible and rigid vegetation under submerged and emergent conditions, and then presented a hydraulic model to compute flow discharge in vegetated channels. The drag effect of vegetation is considered in roughness coefficients in the determination of channel conveyance. The sediment transport capacity in vegetated channels has also been investigated. The bed-load rate is computed using the Wu et al. formula, in which the effective bed shear stress is computed using SRsbγτ=, with S being the channel slope, γ the unit weight of water, and the spacing hydraulic radius defined by Barfield et al. The established models have been tested against experimental and field data. The computed flow discharge and bed-load rate agree well with the measured data.
Description: Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization.
