Sedimentation and contaminant criteria for watershed planning and management: completion report
When precipitation reaches its watershed, part of the water will infiltrate and percolate through the soil as ground water and a large portion of water will form surface runoff. This report is to describe a study on the effect of vegetation on the flow rates, sediment yield, and dispersion of contaminants (such as herbicides, pesticides, and radioisotopes) attached to particles during surface runoffs in watersheds. A model to estimate the resistance of flow due to various combinations of tall vegetation (such as trees) on the order of flow depths is given here. An empirical curve by regression ...
