| dc.description.abstract | The study presents the analysis of bedload transport, changes in the structure armour layer and topogRAPhy of the sediments
during the degradation process. In the analysis of variations in channel slope and bedload composition of actively moving.
The study focused on observations of shear stress on the condition of passive and active conditions on the formation of armor
layer at a constant discharge. Hydraulics Lab studies using the main sediment-recirculating flume of plexiglass dimensionless
width 0.60 m, length of 10.00 m, a depth of 0.45 m and a channel slope of 1% to 3%. Constant discharge capacity of 40 l / s.
Granular material is mixed with a composition of 70% gravel, 30% sand. Running on low flow two phases which phase
equilibrium and armor. The instruments used between digital currentmeter, point gauge meter, sediment feeder, tRAP
sediment, and surfer software version 8.0. The results illustrate the change in the slope of the channel armouring impact on
increasing shear stress. Conditions are shown armor layer structure changes and changes in surface topogRAPhy. While the
grain size profile armor layer more upright, this condition indicates that the formation of armor layer effect on the stability of
the channel. | en_US |
