ANALISIS FAKTOR-FAKTOR YANG MEMPENGARUHI DEBIT SUNGAI MAMASA
Abstract: The research was
conducted in the watershed area of Mamasa. Data was taken for 11 months
starting from December 2006 to October 2007.The research aimed to identify the
influencing factors of the river discharge which were decreasing from time to
time. Data was collected through the application of direct field observation
and literature study. Data on precipitation were gained from 4 stations. The
stations were located in Sumarorong, Mamasa, Minake, and Pana. Data regarding
the river discharge were taken from the office of The Water Source Management
in south Sulawesi Province. Meanwhile, data of land cover were gained from GIS
mapping taken in 1999 and 2003 as well as from Spot 4 in 2007.
Data were analyzed by regression linear model to identify the effect of
independent variable to dependent variable.The results of the research show
that the changes in river discharge fluctuation were influenced by
precipitation and land cover factor. The dominant factor that influenced river
discharge fluctuation were conifers and wide leaf type of vegetations.
