River-Reach Scale definition
River-Reach Scale means the scope of engineering assessments addressing erosion and/or scour problems shall incorporate potential impacts that may extend both up- and downstream of the project site, and not only be limited to the project site boundaries. The term ‘reach’ refers to a segment of the river that exhibits similar hydrologic, hydraulic, and/or fluvial geomorphic characteristics. It is assumed that a river reach will therefore exhibit similar and/or linked fluvial geomorphic characteristics in response to changes that may be implemented within the boundaries of the defined reach.
