Abstract: Hydraulic analyses were conducted to show how floodplains help contain the bottom shear stress, and how vegetation growth may play a role in channel stability. Surface armor was analyzed with respect to channel geometry, channel and floodplain roughness, and bottom shear stress. This analysis helps to shed light on why surface armor exists in some streams but not in others. Channel boundary in urbanized and incised streams is rarely completely relieved from the shear stress of high flows. Field data are presented to illustrate design considerations for restoration of these streams.
