HUBUNGAN DEBIT AIR DAN TINGGI MUKA AIR DI SUNGAI LAMBAGU KECAMATAN TAWAELI KOTA PALU
ABSTRACT: The measurement of
waterflow debit is very needed to know the potency of water resource at a river flow area. Debit is the water volumethat flows in one time. The
consentration time is a needed time for rainfall running off for the farest
spot to the control observed spot. The measurement of waterflow speed can be
used as a tool to monitor and evaluate water balance at one area by approaching
the potency of existing surface water resource. The aimed of the research is to
find out the correlation of water debit and water surface height at Lambagu
River Tawaeli District Palu City. The research was conducted on February to
April 2015 at River Lambagu Tawaeli District Palu City. Furthermore, the data
gathered involved primary data; data gathered in the location directly, they
were the data of the width of river wet profile, the length of river wet
profile, the depth of river wet profile, the speed of riverflow, the height
of surface water, abd rainfall
while the secondary data was the data
that gathered from library, literature, available reports of office and
involved institution, as a supporting data that involved: topography condition,
geomorphologi, land covering, rainfall around Lambagu Riverflow Area for last 4
years that gathered from Palu-Poso BPDAS and climate condition at Lambagu River
of Tawaeli District Palu City. After research procedures were done, the data
gathered analyzed by using logaritme method.The result of the research
showed that the water debit at Lambagu river Pantoloan subdistrict during the
reserach period had the average rate of
0.757 m³/second and the height of water surface at Lambagu river was
about0.26 m. The correlation between water debit and water surface height
showed a strong (positive) correlation in formula of Q = 0.157h0.654x with the rate of correlation (R2)=0.905.
