Decomposition Rates for Hand-Piled Fuels
Year: 2017
Hand-constructed piles in eastern Washington and north-central New Mexico were weighed periodically between October 2011 and June 2015 to develop decay-rate constants that are useful for estimating the rate of piled biomass loss over time. Decay-rate constants (k) were determined by fitting negative exponential curves to time series of pile weight for each site. Piles at the Washington site (k = 0.027/year) decomposed significantly more slowly than piles at the New Mexico site (k = 0.064/year). Significant differences in k for each site may be a function of a between-site variation in pile…

Estimating volume, biomass, and potential emissions of hand-piled fuels
Year: 2009
Dimensions, volume, and biomass were measured for 121 hand-constructed piles composed primarily of coniferous (n = 63) and shrub/hardwood (n = 58) material at sites in Washington and California. Equations using pile dimensions, shape, and type allow users to accurately estimate the biomass of hand piles. Equations for estimating true pile volume from simple geometric shapes and measurements of pile dimensions were also developed for users who require estimates of pile volume for regulatory reporting. Biomass and volume estimation equations were developed to allow users to estimate either…
