Abstract:

Using combined current meter and acoustic measurements, detailed concurrent time series of instantaneous bedload transport rates and flow turbulence have been obtained. The duration, interval and magnitude of significant bedload transport events identified in the time series records are found to have non-standard probability density functions. The bedload time series are analysed statistically in two ways, each providing a method of simulating a series with characteristics similar to the observed data and each capable of estimating instantaneous and total bedload transport rates at the present study site.
