Abstract
This study focuses on the bioengineering materials that were used to protect the
channel from erosion. Hydraulic characteristics of flow through these materials were
determined in term of flow velocities and shear stresses. However determining velocity
of the water requires the use of Manning‟s equation and Manning‟s coefficient of
roughness. Therefore in order to produce „n‟ values for bioengineering materials and
their use in Manning‟s equation there was experiment conducting on different type of
bioengineering material that includes Turf Reinforcement Mat (TRM) and Erosion
Control Blanket (ECB). The result of „n‟ values of bioengineering material were
analyzed and from the result the TRM performed the best for having the higher
resistance towards the flow of water which means it can help to control the erosion of
the channel.
