A North Carolina Piedmont Application of Protocols for Studying Wet Weather Impacts and Urbanization Patterns
Abstract:This research explores the relationship of urbanization to biotic response in the wadeable streams of developing watersheds in the North Carolina Piedmont and describes a protocol, which urban stormwater management agencies can apply in their jurisdiction, to prevent ecologic deterioration that presently occurs in urban streams as a watershed develops. The protocol comprises an eight-step process that involves data collection and analysis integrated with mathematical modeling of runoff from existing and proposed urban development to determine how biologic health indices such as the benthic index of biotic integrity (B-IBI) or Ephemeroptera, Plecoptera, Trichoptera (EPT) richness responds to urbanization of a watershed. Stormwater managers can apply this protocol in their areas of jurisdiction to assist them in developing urban runoff management rules and design criteria with some assurance that the resulting development will minimize negative impacts on the ecology of receiving streams.
