PENGARUH EROSI LAHAN TERHADAP ANGKUTAN SEDIMEN MELAYANG KECAMATAN LHOONG KABUPATEN ACEH BESAR
Abstract: The existence of
Montara river is very crucial because it is the main source of irigation in
Lhoong Subdistrict. One of concerns that
worhtly can be discussed in Montara river is the level of soil erotion. Erotion
and sedimentaion study are done on July through August for a month or 10 days
of rain (thoose that reached the first will be selected) he calculation of
erotion used the USLE equation, while study about sediment in Krueng Montara
Basin is narrowed only for suspended load. The results of this study are the
amount of land erotion and the suspended load discharge in some rainfalls, the
correlation between both of them is determined into some regression models namely linear regression,
power regression and exponential regression. The result shows that the power
regression model is the best model of
all which has a formula as Qs = 6,7953 A1,8791 with R² = 0,8786 or 87 % and
close to 1, it means this model can be used to predict the suspended load
discharge by knowing the amount of land erossion and also the reverse. Besides using
regression model, the relationship between land erossion (A) and suspended load (Qs) s determined by
calculating the suspended load ratio. Based on calculation, the average ratio
of suspend load (Qs) in Krueng Montara basin is 0,00233.
