Field Study of Rainfall Redistribution in Japanese Cypress Plantations
Abstract
To investigate the spatial patterns and temporal variation of rainfall redistribution characteristics in forest plantations, field observation of throughfall was conducted in three forest stands consisting of Japanese cypress (Chamaecyparis obtuse), and Japanese cedar (Cryptomeria japonica), in Tochigi and Kochi prefecture, Japan. Throughfall in 8m × 8m plot was measured at 10 minutes intervals using 20 rain gauges set in a lattice-like arrangement. Throughfall data during the whole observation period were used and divided into several meteorological condition groups according to rainfall and wind characteristics. These data demonstrated that the spatial pattern of throughfall was strongly influenced by rainfall event size.
