Abstract
Recently increased emphasis and attention has been given to river management and restoration of modified streams. A variety of restoration techniques and objectives exist, including asymmetrical cross-section construction, point bar development, two-stage channel design, floodplain approaches, pools and riffles re-creation, and sinuosity and meander restoration. Modifications of the planform geometry can induce undesirable morphological and ecological consequences and significant channel adjustments that, depending on the energy of the flow, can result in failure of the restoration design through either erosion or sedimentation. In this study we provide an analysis of the accuracy of empirical relations of meander parameters for use in meander restoration procedures. A case study in central Maryland is used to demonstrate this analysis. It is suggested that the combination of a field reconnaissance and analytical study should be used to determine the appropriateness of using published regression equations for restoration design.
