The Effects of Submerged Aquatic Vegetation on Flow in Irrigation Canals
It has long been known that vegetation in flowing channels has significant impacts on the flow regime. Invasive aquatic species such as Hydrilla verticillata have become a pervasive and nearly ineradicable part of waterways in the American south. In addition efforts to design flowing wetlands—both as treatment systems and as mitigation for damaged or destroyed natural systems—have been hampered by a lack of pertinent design methods.
