SEDIMEN PREDIKTOR DALAM ANALISA DEBIT DOMINAN
ABSTRACT: One of the most
important variables involved in river-channel formation is the
channel-formingdischarge, which is well known as Dominant Discharge. Since
discharge-sediment relation withinriver morphology process is quite dynamic and
rather difficult to predict, it will be helpful to havea kind of representative
discharge from analytical point of view.This paper discusses on how exponent
(n) of sediment predictor affect dominant discharge deriva-tion. Two sediment
predictors were used on this paper namely Engelund Hansen (EH) and
Meyer-Peter-Muller (MPM). The result shows that, after deriving equations, the
dominant discharge (Q d)could be explained as a maximum distribution value of
piQ n/3 representing combination parameterof both probability and sediment predictor.
Dominant discharge was then calculated based onthose two predictors and
compared with average discharge, frequent discharge as well as
bankfulldischarge. The result presents that analytical approach using EH
predictor provides closer valueto the bankfull discharge.
