The relation between vegetation and storm-water runoff in Portland, Oregon

September 1, 2016
Author(s)
Geoffrey Donovan, David Butry
Past research has examined the effect of urban trees on storm-water runoff using hydrological models or small-scale experiments. However, there has been no statistical analysis of the influence of trees on runoff in an intact urban watershed. We address
