... year after winter harvest in four of the watersheds. Mechanical and chemical site preparation was also conducted before and during the post-harvest sampling period. During the growing season, TDP and PP concentrations in streams draining harvested watersheds were higher than in the reference streams...

... sorties du modèle au niveau de détail des produits cartographiques utilisés est discutée. Use of dynamic models supports recent efforts to introduce integrated watershed management policies in Canada. A unique and largely transferable implementation of these models is needed to facilitate water...

...G. T. Parker; R. L. Droste; K. J. Kennedy The South Nation (SN) watershed in Eastern Ontario was studied for improvements in surface water quality due to best management practices (BMPs). Contributions of non-point sources (NPS) to nutrient loadings are both significant and poorly defined...
