Description :
This paper presents an overview and first results of a research project on gully monitoring which employs large-scale aerial photography taken from remote-controlled platforms. The resulting high-resolution images are employed for photogrammetric and GIS analysis in order to quantify gully development with linear, areal and volumetric measurements at various sites in semi-arid landscapes of Spain and Africa. Linear headcut retreat rates for 12 gullies (in Southeast Spain, South Morocco, Burkina Faso) were analysed in order to investigate their relation to patterns of runoff and infiltration behaviour in the gully headcut surroundings.
