Research Abstract

The infiltration capacity was measured by using an oscillating nozzle rain simulator to estimate infiltration capacity of forest road surface and analyze the associated factors. The experimental results showed that the mean infiltration capacity of forest road surface was 33.3 mm/h. Bulk density and porosity were significantly correlated to infiltration capacity. Findings from both field experiments and monitoring can be applied for prediction rainfall-runoff from forest road surface which is important to be examining road runoff contribution at a watershed scale.
