Inter-annual variation in rainfall interception at a hill evergreen forest in northern Thailand

An observational study on rainfall interception at a hill evergreen forest in northern Thailand was conducted for 4 years. The fractions of stemflow, throughfall and interception to total rainfall were 1.5, 89.1, and 9.3 %, respectively. Throughfall per one observation occasionally exceeded rainfall...

Summary:An observational study on rainfall interception at a hill evergreen forest in northern Thailand was conducted for 4 years. The fractions of stemflow, throughfall and interception to total rainfall were 1.5, 89.1, and 9.3 %, respectively. Throughfall per one observation occasionally exceeded rainfall. These extra throughfall were caused by underestimations of rainfall and by additional precipitation, which was produced by fog occurrence, to forest canopy in the Kog-Ma watershed. Considering errors in estimating rainfall just above the interception study site gave possible ranges of interception amount in each year. These annual interception rates varied year to year.
