The author argues that the two primary ecological factors determining the life of organisms in running water are hydraulics (current and flow) and the transit time of nutrients and pollutants, which are also the two factors most likely to be modified by human activity. He explores the operation of these and other ecological factors and explains the impact of watercourse development, eutrophication, and toxic pollution.
