Project Summary: The purpose of this project is to determine what effect native grasses have on the capacity of the Anacostia river channel to convey flood discharges using the hypothesis that native grass and herb plantings will decrease flow resistance and increase the flood-carrying capacity of the channels at high flows. The study shall provide a detailed assessment of whether the plantings of native grasses and herbs on the banks of rip-rap protected channel affects flow resistance and the carrying capacity of the channel and detailed guidance on how to determine the changes in flow resistance (expressed as Mannings n) of the channel banks due to re-vegetation
