[1] [2] It may also be designed for land reclamation after mining, or as a mitigation step for natural areas lost to land development. Constructed wetlands are engineered systems that use the natural functions of vegetation ...
Free flow E-Y diagram depiction. Illustrated above is a unitless E – Y diagram and how Energy and depth of flow change throughout a Parshall Flume. The two blue lines represent the q values, q 1 for the flow before the constriction, and q 2 representing the value at the constriction (q = Q/b = ft 2 /s, or flow over width in a rectangular ...
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.
