Effect of aquatic vegetation on the channel capacity of rivers and canals
Conclusions When evaluating the effect of vegetation on the capacity of open channels, the degree of filling the channel cross section with overgrowth, characterized by the ratio $ ω_{v} $/ω, and densith of the vegetation N should be considered the most significant factors.Graph 1 in Fig. 1, which is confirmed well by the prototype data, can be used for determining the roughness coefficient of channels with vegetation in them. The graph is applicable for conditions when the overwhelming part of the vegetation is composed of species with stiff stems (reed, cattail, and also regularly arranged overgrowths of shrubs and trees) with no interface above the plants.The formula obtained analytically and given in the text should be used for estimating the roughness coefficient in the case of completely submerged vegetation with stiff stems (a part of the flow moves above the vegetation).After determining the values of n, the channel capacity is calculated by the Chezy formula.
