摘要：	Storm water quantity control has long been a challenge for highway designers. Traditionally, centralized best management practice designs are often cost prohibitive and inefficient in many rural highway applications. The use of existing vegetated rights-of-way as a method of treating storm water, a component of the broader storm water treatment concept more generally referred to as low-impact development, has become a primary focus of the Washington State Department of Transportation. To design and use such storm water management controls adequately, however, further research and correlation between numerical infiltration-runoff models and field experiments were needed. This paper focuses on evaluating natural dispersion performance through the use of simulated rainfall runoff data collected with a field-scale rainfall simulator and a numerical model to study the effects of slope length, angle, and impervious contributory area on natural dispersion applications. A simple new equation was developed to analyze natural dispersion performance on the basis of multiple variables. The research and resulting evaluation procedure indicated that the use of natural dispersion as a storm water quantity control strategy is applicable to many roadside areas in Washington State.
