Abstract

The aim of this study was to relate gully volume to planimetric parameters of irregularly shaped gullies developed in the sandstone substratum of the Fortuna geological formation. The AA. established relationships between gully volume and its complex geometry. For this purpose the top view areas and lengths of eight gullies were digitized and monitored on rectified air photographs of 1962, 1974 and 2000 using a Geographic Information System (Arc View). Half of these gullies were located in an area with a gentle slope gradient and the other half with steep slope gradient. Using the relationships established from 4 measured gullies, the results highlight that the obtained values of gully sediment yield are comparable to that of others formations in similar climate
