Paperback. Condizione: New. Print on Demand. This book explores the use of jet roofs as wind deflectors to prevent and reduce snow cornice and cushion formation. As wind accumulates on the lee slope of mountains, it can lead to dangerous avalanches. By deploying a jet roof, wind is redirected down the slope and kept from forming snow deposits. The book details a mathematical model created by the author to help predict the size and shape of jet roofs needed to most effectively alter wind patterns and reduce the risk of avalanches. Jet roof placement, length, and angle relative to the slope are all considered in this model. The author concludes that jet roofs are valuable assets in avalanche control when properly configured, offering a valuable design tool for their implementation.

Paperback. Condizione: New. Print on Demand. This book introduces a new computer program that analyzes avalanche runout distance, speed, and depth of debris in runout zones. The user inputs variables such as the avalanche path's longitudinal profile, snow thickness, and two friction coefficients which the program then uses alongside the Navier Stokes equations to model the avalanche. The program also allows for adjustment of input variables relevant to the avalanche's path, such as slope angle and varying surface friction. The author successfully tested the program in a variety of avalanche cases and determined the sensitivity of runout distance to various parameters. This book is an innovative and practical contribution to the field of avalanche science, with its modeling techniques providing valuable insights into the complex dynamics of avalanches.
