The seasonal changes in both air temperature and rainfall show that this area has three seasons: a rainy season, an early (or cool) dry season and a late (or hot) dry season. The sub-watershed has an area of 8.63 ha covered with hill evergreen forest at a continuous canopy height of approximately 25-40 m. The dominant plant family is the Fagacea, including Lithocarpus, Quercus,and Castanopsis genera.The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system."],
