This research study explores the relationship of urbanization to ecology in the wadeable streams of developing watersheds and describes a protocol, which urban stormwater management agencies can apply in their jurisdiction, to prevent the severe ecologic deterioration that presently occurs in urban streams as a watershed develops. The protocol comprises an 8-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.
A colouring book of abstract patterns and mandalas designed to calm your mind and relieve your stress.
This book contains twenty original patterns in various styles and differing levels of intricacy, with two copies of each image to make forty pages to colour. The images are printed on a single side of the paper to help prevent bleed-through. We recommend putting a sheet of paper or card between pages if using strong inks. The back of each page is marked with a cutting line to aid removal of pictures.
