Abstract
In this study of rainlfall characteristics, throughfall was high!y positively cor- related with precipitation. Stemflow and interception were positively correlated with precipitation. Rainfall intensity did not significantly affect the stemflow or interception components, though throughfall was shown to increase with increasing intensity for rainfall events up to 6 mm aggregate. A positive relation was shown between tree size and interception, while negative relationships were found between tree size, and throughfall and stemflow for various classes of precipitation events. Volume of stem- flow waters was positively related to tree size. The results are discussed in terms of soil infiltration characteristics, and the woodland community.
