Hydrology and Hydraulic Design Criteria for the Creation and Restoration of Wetlands.

摘要

Hydrology is generally accepted as the single most important factor governing the successful establishment and maintenance of specific wetlands types and wetland processes. Long before the study of wetlands was a separate field of science, early scholars recognized the importance of hydrology in the establishment of wetland types and the attainment of wetland functions. Still, many wetland establishment or restoration projects fail because the proper hydrology and hydraulics needed to meet the project goals were not attained. Failure to establish the correct hydrology can result in a different type of wetland than desired or mandated, no wetland, or a failure to achieve desired functions and the establishment of undesirable flora and fauna. This technical note provides hydrology and hydraulics informational background for four basic wetland types along with important considerations in developing fictional design.
