Book excerpt: Excerpt from Mechanisms of Fire Spread Research Progress Report No. 2: Field Study Under Grant No. Nsf-G-16303 Slash was collected, and 24 plots were prepared at the Priest River Experimental Forest in May 1962. Lodgepole pine and Douglas-fir slash from full tree crowns was collected on nearby State of Idaho lands in active logging area. The bole and large tree limbs were not included. Only the tree tip (4 feet to 6 feet) was included with the branches. This slash was hauled to an experi mental burning area on a flat at the south west end of the experimental forest.nations were necessary to calculate the wet weight loading of fuel beds which would yield and tons per acre dry weight. Boundaries for experimental burning plots were laid out with stakes and strings. Thirty six 6 by 60-foot plots were staked in 6 by 6 foot increments (10 increments for 60 feet). Some plots were not used because of irregularities or roughness of the ground. Twenty-four plots were assigned fuel loadings by random selection. The plots were repli cated four times for the two species and three loadings. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Equations describing flow in bouyant turbulent jets have been applied to the derivation of characteristics for forest fire flames. Approximate solutions are used to develop relationships for flame lengths, angles, heights, and tip velocities for fires heading with the wind and burning in calm air as functions of Byram's fire intensity. I. (Btu/ft-sec). Flame length and velocity relationships are tested with data taken during controlled burns in southern fuels and with data from the literature. Backfire data are described by the equations for calm-air conditions. Both theoretical and experimental results show that flame lengths for backfires and headfires vary as I-2/3 and I-1/2, respectively; flame tip velocities vary as I-1/3 and I-1/2.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains some contributions presented at the Applied Mathematics for Environmental Problems minisymposium during the International Congress on Industrial and Applied Mathematics (ICIAM) held July 15-19, 2019 in Valencia, Spain. The first paper addresses a simplified physical wildfire spread model, based on partial differential equations solved with finite element methods and integrated into a GIS to provide a useful and efficient tool. The second paper focuses on one of the causes of the unpredictable behavior of wildfire, fire-spotting, through a statistical approach. The third paper addresses low -level wind shear which represents one of the most relevant hazards during aircraft takeoff and landing. It presents an experimental wind shear alert system that is based on predicting wind velocities obtained from the Harmonie-Arome model. The last paper addresses the environmental impact of oil reservoirs. It presents high-order hybridizable discontinuous Galerkin formulation combined with high-order diagonally implicit Runge-Kutta schemes to solve one-phase and two-phase flow problems through porous media. All the contributions collected in this volume are interesting examples of how mathematics and numerical modelling are effective tools in the field of environmental problems.
