Feedbacks between erosion and sediment transport in experimental bedrock channels
Natural bedrock rivers flow in self-formed channels and form diverse erosional morphologies. The parameters that collectively define channel morphology (e.g. width, slope, bed roughness, bedrock exposure, sediment size distribution) all influence river incision rates and dynamically adjust in poorly understood ways to imposed fluid and sediment fluxes. To explore the mechanics of river incision...
متن کاملBedload transport in the instrumented catchment of the Rio Cordon Part II: Analysis of the bedload rate
Sediment transport is monitored by a specially designed instrumentation installed on a steep Ž . mountain streams the Rio Cordon . The variability of bedload rate and yield reflects the Ž . variability in flow discharge. Bedload and flow data for ‘ordinary’ low peak flow floods and ‘exceptional’ sediment transport events are used to test the range of application of the bedload equations propose...

Sediment transport-storage relations for degrading, gravel bed channels
[1] In a drainage network, sediment is transferred through a series of channel/valley segments (natural sediment storage reservoirs) that are distinguished from their neighbors by their particular capacity to store and transport sediment. We propose that the sediment transport capacity of each reservoir is a unique positive function of storage volume, which influences sediment mobility and avai...
متن کاملExponential Formula for Bedload Transport
An exponential formula that does not involve the concept of the critical shear stress is derived in this study for computing bedload transport rates. The formula represents well various experimental data sets ranging from the weak transport to high shear conditions. Comparisons of the present study are also made with many previous bedload formulas commonly cited in the literature.
