Study on roughness coefficient at natural channel

Md Ali, Zarina and Abdul Karim, Nur Husna and Mohamad Razi, Mohd Adib Study on roughness coefficient at natural channel. In: International Conference on Environment (ICENV2010), 13-15 Disember 2010, Pulau Pinang.



Roughness coefficient for open channel has been study widely to alleviate engineers to manage flood problem or to design the hydraulic structures. Dissimilarity of n values occurs especially at two or more different locations due to channel properties, geometry and other factors. The study was carried out Parit Karjo channel to determine a range of value for roughness coefficient and its relationship with flow rate. In-situ measurement was carried out at 10 stations along Parit Karjo channel in order to determine velocity of flow. The result shows the range of roughness coefficient, n is ranged from 0.04 to 0.48. As conclusion, the states of flow for Parit Karjo channel are located between transitions to turbulent flow region.
