Agricultural sources impacting on stream water quality : investigations and characterizations / Howard Y.F. Ng. : En13-5/96-166E-PDF

"This report presents the results of evaluation of the magnitudes of losses of five nutrients (phosphorus, ammonia, nitrate, nitrite, and potassium), and two herbicides (atrazine and metolachlor) from an agricultural watershed during the runoff event flow and baseflow. The study identified that the losses of nutrients were substantially higher (up to 94%) in baseflow as compared to. the runoff event flow. Conversely, exported herbicides were mainly transported by surface runoff and interflow (up to 72%) rather than by the baseflow. The results of this work will be presented at the Canadian Water Resources Association Conference addressing those involved in watercourse management and design which links their practices with an ecosystem, (Watercourses - Getting on Stream with Current Thinking Conference to be held at the Hyatt Regency, Vancouver, B.C. October 22-25-, 1996)"--Management perspective.
