Mechanics of debris flows and debris-laden flash floods Mechanics of debris flows and debris-laden flash floods
A new mathematical model developed to predict behavior of debris flows and avalanches also holds promise for predicting behavior of debris-laden flash floods. The model assumes that debris flows behave as mixtures of interacting Newtonian fluids and Coulomb solids. Solid and fluid constituents obey three-dimensional mass and momentum balances, which are summed and depth-integrated to...

A strategy for estimating tree canopy density using Landsat 7 ETM+ and high resolution images over large areas A strategy for estimating tree canopy density using Landsat 7 ETM+ and high resolution images over large areas
Forest cover is of great interest to a variety of scientific and land management applications, many of which require not only information on forest categories, but also tree canopy density. In previous studies, large area tree canopy density had been estimated at spatial resolutions of 1km or coarser using coarse resolution satellite images. In this study, a strategy is developed for...
