Downstream patterns of bed material grain size in a large, lowland alluvial river subject to low sediment supply
[1] A new data set of bimodal subaqueous channel bed sediments was analyzed for longitudinal patterns in grain size. It yielded two interesting observations: (1) separate fining trends in d50 exist for gravel and fines that overlap for 175 river kilometers, and (2) this overlap in fining trends results in a protracted (nonabrupt) gravel to sand transition. These suggest bed patchiness that is i...
متن کاملThe use of short-lived radionuclides to quantify transitional bed material transport in a regulated river
We investigate the use of the short-lived fallout radionuclide beryllium-7 ( Be; t1/2 = 53·4 days) as a tracer of medium and coarse sand (0·25–2 mm), which transitions between transport in suspension and as bed load, and evaluate the effects of impoundment on seasonal and spatial variations in bed sedimentation. We measure Be activities in approximately monthly samples from point bar and stream...
متن کاملA river bed hydrokinetic turbine. A laminated composite material rotor design
This chapter presents the composite materials applied to Water Current Turbine (WCT) hydrokinetic turbines. Here will be briefly described the features of these turbines, the fluiddynamic behavior of the rotor, and its structure formed into a composite material. From the structural viewpoint an advanced composite material formulation that allows an appropriate structural design is introduced. T...
متن کاملNumerical computation of seepage erosion below dams (piping)
In delta areas the land is protected from floods and high tides by dikes. In general these are constructed of impervious clays and built on a sandy aquifer as subsoil. Such structures are vulnerable to an erosion effect called piping. The actual word 'piping' refers to the development of shallow channels in the sand below the dike, which begins at the downstream side of the structure. Here ofte...
متن کاملReliability Analysis of Free Jet Scour Below Dams
Current formulas for calculating scour depth below of a free over fall are mostly deterministic in nature and do not adequately consider the uncertainties of various scouring parameters. A reliability-based assessment of scour, taking into account uncertainties of parameters and coefficients involved, should be performed. This paper studies the reliability of a dam foundation under the threat o...
