| Outline of Final Research Achievements |
Throughfall drop generation process was clarified. A technique was established to divide throughfall into three drop components, which were free throughfall, splash throughfall, and canopy drip. Through the technique, the influence of tree species, presence and absence of leaves, rainfall intensity, and elapsed time from the onset of rainfall was analyzed for throughfall drop generation process. Rainwater physics of adhesion and transfer on the foliage was clarified based on the measurement of hydrophobicity of the foliage surface. Above all, it is elucidated that the occurrence of adhesion, sliding, and detachment of rainwater from the foliage surface was different between leafy and woody surfaces.
