Estimating Windspeeds For Predicting Wildland Fire Behavior PDF Download

Excerpt from Estimating Windspeeds for Predicting Wildland Fire Behavior By equating integrated bulk drag due to crown foliage to the shear stress at the top of the crown layer, a model for relating windspeed within and below a uniform forest canopy to windspeed 20 ft (6 m) over the canopy is developed. Important variables in this model include stand height, crown closure, foliar surface/ volume ratio, and crown bulk density. Comparison of model predictions with reported experimental measurements shows good agreement. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
