Modeling the effects of mining and erosion on biomass production
1987
Rogowski, A.S. | Weinrich, B.E.
A biomass productivity model and a soil loss model were used to simulate effects of mining and erosion on the productivity potential of a 600-ha site. Biomass productivity, expressed as a relative productivity index pi (Full-size image (<1 K)), was computed as a product of a root distribution function and limiting soil property levels derived from literature. Distribution of soil loss or deposition was estimated using a recently developed erosion-deposition model. Effects of two scenarios are compared. In the first, the site is assumed to have been surface mined for coal and the effects on productivity are examined if existing soil is replaced with a minesoil. In the second, erosion-deposition model is used to predict changes in productivity after a severe storm. Under the assumptions of this study, biomass productivity appears more likely to decline because of mining than because of erosion.
