The difference
of vegetation profile is having role to hydrological system in
watershed. This is due to each vegetation has different model of
architecture. Certain models of architecture influence translocation of
water to surface runoff and erosion and parameters hidrological others.
This research aims to find out the characteristic of model tree
architecture, level of surface runoff and erosion of Aubreville’s model,
Leeuwenberg’s model and Stone’s model and to find out effect of rainfall
on surface runoff and erosion. Measurement of surface runoff and erosion
was done using rectangular plot system. Plot size was 2 meters wide, 22
meters long and 0,25 meters high. Regression analysis was used to
uncover the effect of rainfall on surface runoff and erosion. The
results showed that the smallest surface runoff and erosion occurred in
Stone models. The influence of rainfall on surface runoff Aubreville
model 57%, Leeuwenberg model 59%, Stone model 73%. The influence of
rainfall on erosion Aubreville model 75%, Leeuwenberg model 78%, Stone
model 84%. How to cite this article: Naharuddin, Bratawinata A, Hardwinarto S, Pitopang R (2016). Tree Architecture Model Characteristic and their Effects on Surface Runoff And Erosion In Gumbasa Sub-Watershed, Central Sulawesi, Indonesia. Acad. Res. J. Agri. Sci. Res. 4(5): 222-230
