Impacts of Stormwater Management Practices and Climate Change on Flow Regime and Channel Stability
… water. This increase in runoff contributes to channel erosion. While extensive research exists on the hydrologic benefits of various types of stormwater control measures (SCMs), the relationship between urbanization, widespread SCM implementation, and channel stability in headwater streams …

The Influence of Bank Vegetation on Flow Structure Within a Small Agricultural Stream: Implications for Channel Stability
… on the flow, sediment transport, and ultimately channel form. Although past studies in fluvial geomorphology have largely ignored the complicated role ofinstream and bank vegetation, some recent studies have attempted to characterize flow in vegetated environments. There is, however, still a need …

Land Use and River Systems: Impacts of Suburban Residential Development on Channel Stability and Water Supply, Oak Ridges Moraine, Southern Ontario
… in Caledon East, Palgrave, and Bolton. Channel morphology was assessed via bank soil strength measurements, vegetation cover, quantification of large woody debris, and visual assessment, allowing for inferences about potential downstream bank degradation symptomatic of streams in urban …

Sediment Transport Analyses and Development of a Hydraulic Computer Model for Desiging a Stable Vegetated Channel at Lost Lake
… Lake. Remedial action should be taken to enhance channel stability during extreme runoff events. The primary objective of this project was to develop recommendations to enhance the stability of the stream channel for Little Clipper Creek and Clipper Creek extending downstream to the earthen dam at …

Flow, sediment transport, and bed topography in straight and curved gravel-bed channels
… projects have aimed to restore natural channel stability and dynamism by re-establishing channel meanders lost to historical channelization. An understanding of meandering channel behavior is crucial to successful restoration of these rivers. Meandering and straight channels differ …

Stability analysis of natural circulation in BWRs at high pressure conditions
… of this work is to assess the characteristics of stability in a NCBWR at rated conditions, and the sensitivity to design and operating conditions in comparison to previous BWRs. Two kinds of instabilities, namely Ledinegg flow excursion and Density Wave Oscillations (DWO), have been studied. The …

Development of a regional curve to relate discharge and drainage area to hydraulic geometry for the Red River of the North Basin
<p> Restoration of riparian corridors and stream channels is important for many reasons, including preserving water quality, maintaining channel stability and controlling floods. Regional hydraulic geometry curves allow estimation of stable hydraulic geometry relationships that are necessary to …

Downstream change in channel hydraulics along the River Severn, UK
… which control the catchment-scale variation of channel stability, sediment transport and siltation, flood generation and aquatic habitats. However, little attention has been given to quantifying the detailed spatial and temporal variability of channel hydraulic parameters, despite considerable …

Extending the Capabilities of Time Delayed Haptic Teleoperation Systems
… As the time delay from the communication channel increases, system stability and performance degrade. Previously, solutions focused on communication channel stability and environment force estimation methods that primarily rely on linearization of the Hunt-Crossley (HC) contact model. …

Evaluating the Long-Term Morphological Response of a Headwater Stream to Three Restoration Techniques
… Many projects follow the guidelines of Natural Channel Design and use in-stream structures to stabilize stream channels. Post-project monitoring rarely exceeds 3-5 years, and the lack of guidance, funding, and pre-restoration data prevents meaningful post-project assessment of the design …

Isolation and characterization of channel-forming proteins in the outer membrane of E. coli and Borrelia species
… fluctuations were obtained from single-channel experiments with outer membrane preparations of B. hermsii, B. recurentis and B. duttonii. All strains had a different conductance fluctuation pattern with a broad range of single-channel conductance values varying from 0.5 nS – 11 nS. …
