This paper seeks to review the progress that is being achieved by
fluvial geomorphologists in making use of digital photogrammetry for
river channel research. Fluvial geomorphology is first placed in a
basic historical context from which the failure to make full use of the
potential of photogrammetry is noted. A review is then given of the
ways in which fluvial geomorphologists are now making use of
photogrammetry, recognizing that the development of digital approaches
has both made photogrammetry a more cost-effective tool and also
introduced a range of new research questions. The main objective of
this paper is to demonstrate the importance of these questions and to
illustrate some of the ways in which they are being addressed. Special
attention is given to the issue of data quality, which is frequently
(and perhaps conveniently) ignored.
