The EFFECT OF HYDROPHYTES ON THE PERFORMANCE OF SECONDARY CANAL

open access: yesJOURNAL OF WEED SCIENCE RESEARCH, 2021
The hydrophytes in canal effect directly canal performance by reducing water velocity, enhances sedimentation and reduce canal cross section area which raise water level and reduces water flow. Indirectly the hydrophytes detaches from their origin and flow with water stuck with outlet and reduces its proportionality.
