Effective Discharge in Fluvial Geomorphology

Summary

Use statistically and empirically based solution techniques to calculate the effective discharge of a stream. Students are given a 10-year record of river data on water and bedload discharge, flow frequency, and maximum daily discharge for each year. They must use the data to construct a rating curve for bedload transport, determine total volume of sediment transported by each flow-magnitude class, and discuss the recurrence interval of the effective discharge. Real and fictional data can be used.
