Abstract

Rainfall partitioning using vegetation canopy is the main component of the hydrological processes that is directly related to net rainfall, which can be both on the surface and into the soil. Canopy rainfall partitioning is a fundamental component to study the hydrological implications of water resources management in ecosystems. This study aimed to compare the amount of rainfall interception and rainfall partitioning between a mixed fruit tree–based agroforestry system under normal conditions compared to after a landslide (9 years ago). The results showed the average percentages of throughfall, stemflow and canopy interception were significantly different during normal conditions and the 9-year landslide. Garcinia mangostana intercepted more rainfall that any other tree species (45.01% during an individual rainfall event), followed by Lansium domesticum (37.0%) and Durio zibethinus (32.92%), respectively. In case of the 9-year landslide, the average percentage of interception by Maesa ramentacea was higher than Macaranga denticulate with values of 34.41% and 28.28% during each rainfall event, respectively.
