Phosphorus and Nitrogen Removal Efficiencies of Infiltration Trenches

Wave Interaction with Fluid Mud in Rectangular Trench
Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small-amplitude wave theory. The problem was formulated using the Voigt model for an viscoelastic...

Slide Stabilization with Stone-Fill Trenches

Ongoing Monitoring Results Pilot Stormwater Disposal Facilities, Pierce County, Washington
The three stormwater disposal facilities evaluated appeared to increase in pollutant removal effectiveness after approximately 4 to 5 months of operation. This may be due to the deposition...
