Abstract :
Bili-bili dam is located in the upper part of
the Jeneberang river where in this area there is an
automatic water level measuring device or AWRL
(Automatic Water Level Recorder). Continuous river
discharge monitoring is very necessary to evaluate the
watershed in the long term. The method used in
monitoring the discharge is the discharge curve method
or rating curve. The use of flow rate curve data that is
not up to date can cause an error in the estimation of
flood discharge. The purpose of this study is to find out
how much is the debit and the percentage difference
from the Rating Curve equation generated through the
statistical and arithmetic methods. The method used in
determining the price of H0 is Arithmetic. The results of
this study conclude that the rating curve equation in
2009-2015 statistic method is Q = 3,335 X (H-83,67) 0,98
in 2016-2019 is Q = 5,898 X (H-88,67) 0,86 while
arithmetic method in 2009-2015 is Q = 5,419 X (H-83,67)
1 in 2016-2019 is Q = 8,033 X (H-88,67) 1 and the
difference in the value of river discharge and calculated
discharge with statistic method in 2009-2015 an average
of -3,036% in 2016-2019 an average of -1,68% while in
arithmetic method in 2009-2015 an average of 72,13% in
2016-2019 an average of -71,65%. The result of this
study are expected to be a reference method that can be
used to calculated river discharge in other areas.
