Abstract

This study details the levels of accuracy that can be achieved using the RolleiMetric Close-range Digital Workstation (CDW) photogrammetric survey technique on a variety of low relief fluvial geomorphic features (lateral, point and mid-channel bars). Guidelines are provided on field technique designed to minimize errors in the mapping of a terrain surface and to determine the necessary minimum target density for a given level of accuracy. The technique may then be incorporated into a revised methodology for sediment budgeting to provide a more accurate estimate of sediment flux rates that can be estimated on an event basis following repeat photogrammetry
