Performance and Design for Compost Erosion Control and Compost Storm Water Blankets

摘要

Recent peer reviewed research from major land grant universities has shown compost erosion control blankets reduce soil erosion, reduce nutrient loading (nitrogen and phosphorus), increase vegetation cover and biomass, reduce runoff volume and peak flow rates relative to conventional best management practices. This paper will review these research papers and utilize the reported results to establish design values for compost blankets used in slope stabilization (compost erosion control blankets) on disturbed soils and for runoff reduction (compost storm water blankets) for Low Impact Development (LID) design applications. Specifically this paper will report on the effects of particle size specifications on performance, single event cover management (C) factors (soil loss ratio), low impact development design objectives, initial abstractions, runoff curve numbers (CN), and runoff coefficients for compost erosion control and storm water blankets.
