520 _aDue to the pressing and permanent need for the fresh water running in open channels, the challenging problems facing water flow management should be controlled continuously. One of these problems is the growth of aquatic weeds in waterways. They have negative impacts on the hydraulic efficiency of the open channel. The present experimental study has been carried out, to examine the effects of barrier screen on the hydraulic efficiency of open channels in presence of different accumulations of weeds. The barrier screen is one of the most common ways used to handle the problem of aquatic weed invasion through waterways. A number of scenarios with different discharges and water depths in case of different weed densities were experimented. The water surface profiles and water velocity profiles for each scenario were examined, and recorded. Analyzing the final results, a new empirical formula could be obtained correlating weed characteristics and flow characteristics
