This study aims to quantify the amount of canopy storage capacity, to determine the canopy interception values and to investigate the effects of rainfall intensities to interception loss for Axonopus compressus (Dwaft) as floor vegetation under laboratory conditions. A rainfall simulator, Kohler GHE20 Hydrology apparatus, has been applied to produce an artificial rainfall with three different intensities. General water balance equation was applied where the changes in water storage between barren land and land with canopy cover was recorded to obtain the interception loss amount. Canopy storage capacity determined from this study was 1.35 to 0.48 mm for 90 to 180 mm/hr rainfall intensity, respectively. Meanwhile, the canopy interception obtained is 3 to 18% from the rainfall depth. © Published under licence by IOP Publishing Ltd.
