Under certain conditions and in response to dramatic shifts (i.e., significant vegetation loss) or significant weather activity (i.e., intense rainfall or snowmelt) in the upstream environment, debris flows can manifest and have devastating impacts on downstream environments and communities. During their transport downstream through meandering distributary channels, debris flows can incise into the channel bed and laterally into channel banks. Debris flows can also rise and overtop the banks of their confining channels. These overtopping events are especially prevalent along channel bends where increases in centrifugal forces influence manifestations in debris-flow superelevation. This study investigates the parameter of channel bend curvature for debris-flow-driven avulsion using a debris-flow flume housed in the ECU Geomorphic Modeling Laboratory and series of 3D-printed rectangular channels of differing sinuosity imprinted in a simulated alluvial plain. The results of this experiment suggest variability in channel curvature (sinuosity) influences variability in manifestations of debris-flow runout and inundation behaviors, including debris-flow avulsion location, volumes and distances of debris-flow runout, and channel bend and alluvial plain inundation. Specifically, greater volumes and surface area coverages of debris-flow runout are suggested to result from avulsions from sharper curves as opposed to wider curves. Zones of likelihood of inundation that incorporate these findings are presented for areas of intersect between debris flows and channel outer bend crests on the debris-flow flume. Sharper curves are also suggested to influence greater frequency of avulsion. Lastly, this study demonstrates the potential for debris-flow avulsions to occur in channels free of debris pileup and as direct results of flow superelevation.Item Restricted Spatial analysis of broadband service :identifying the digital divide in North Carolina(East Carolina University) Suvak, William J.; Crawford, Thomas.; Geography, Planning and EnvironmentItem Restricted Frequency/magnitude of aeolian events(East Carolina University) Swann, Christy.; Gares, Paul.; Geography, Planning and EnvironmentItem Restricted Hurricanes :where does the knowledge begin?(East Carolina University) Stein, David N.; Gares, Paul A.; Geography, Planning and EnvironmentItem Restricted Paradise is relative :implications of labor transition in the crab processing industry of eastern North Carolina(East Carolina University) Selby, Emily F.; Hapke, Holly M.; Geography, Planning and EnvironmentItem Restricted Characterizing jurisdictional wetlands using aerial LiDAR(East Carolina University) Shaeffer, David L.; Allen, Tom.; Geography, Planning and EnvironmentItem Restricted Volumetric changes in morphologic zones adjacent to inlets in microtidal barrier islands, Outer Banks, North Carolina(East Carolina University) Renken, Katherine Anne.; Gares, Paul.; Geography, Planning and EnvironmentItem Restricted Central place theory as applied to the counties of southeastern North Carolina(East Carolina University) Todd, William Smith,1920-; Dunigan, C.
