ABSTRACT: Roughness of canal
give effect to the speed of the water flow in it, which in the next, will
affect tothe efficiency and size of
canal. Factors that
affect to the
canal roughness values
are wet surface
canal constituent materials;
The physical properties of the
soil in canal; Irregularity of the canal; Vegetation growing in canal and
scouring and deposition factor in canal. Research results indicated that scouring
occured in canal which effect to the
irregularities inthe canal, so that solidify soil and material
loading in canal surfacewere needed. At the tertiary canal one manning
roughness value was 0.0462 and chezy was 13.78; at the tertiary canal two
manning roughness value was 0.0387 and chezy was 15.98 and at the tertiary
canal three manning roughness values was 0.0574 and chezy was 11.38.
