What is Manning Roughness Coefficient in Vegetated Channels about?

The study investigates the Manning roughness coefficient in vegetated open channels, emphasizing the impact of aquatic weed infestation on flow resistance. It presents two equations to estimate the roughness coefficient based on parameters such as weed density and water surface slope, validated through laboratory experiments. The findings indicate that higher weed density significantly increases the roughness coefficient, affecting the hydraulic efficiency of the channels.
