The research project MoGul (Large-scale Monitoring of
Gully Erosion in Semi-Arid Landscapes) at Trier and
Frankfurt University investigates the various types,
development and dependencies of gullies as well as
geomorphological processes involved in gullying. The
investigations are carried out at different sites following a
transect from the semi-arid Ebro Basin in Northeast Spain,
via the sub-humid Baza and Guadalentín Basins in
Southeast Spain and the arid Drâa Valley in South Morocco
to the semi-arid Oudalan in Sahelian Burkina Faso.
Investigations on short-term gully change are mostly
realised using field methods for quantification of linear
headcut retreat rates. The lack of image resolutions
corresponding to the magnitude and dynamics of gully
erosion usually prevents the use of remote sensing data,
which in contrast to field measurements allow for the rapid
and spatially continuous coverage of a site (Marzolff, 1999;
Ries and Marzolff, 2003). The objective of this paper is to
present an overview of the first results of the MoGul project
on gully monitoring which employs large-scale aerial
photography taken from remote-controlled platforms (hot
air blimp and kites). [--]
