Description :
An approach proposed here, using a few observations of small transport rates to calibrate a transport formula, is likely to provide a superior combination of accuracy and effort and substantially reduces flow-scaling error. Small transport rates can be measured effectively using pit samplers, which allow the sampling period needed for accurate measurements. Grain size can be represented as 2 fractions, sand and gravel, which capture some of the important transport dynamics and effectively represent important environmental problems within a tractable methodological approach.
