Title: Estimating the zero-plane displacement and roughness length for tall vegetation and forest canopies using semi-empirical wind profiles

Abstract

A simple method based on a mass-conservation principle is presented for estimating the aerodynamic characteristics of forest and tall vegetation canopies. The method uses semi-empirical modifications of the profiles in the transition layer, eliminating the need for measured wind data extending into the logarithmic regime. Also, various schemes are presented for determining the transition-layer depth z[sub *] in terms of the particular physical characteristics of the canopy. 10 refs., 3 figs.
