Abstract
To develop and calibrate a systematic approach for gullies identification from Digital Elevation Models we measured morphological characteristics of gullies at the Calhoun CZO. Gullies reference perimeters have been defined by a Georgia Tech team during a field survey (June 29-30 2015) through a visual identification of the change in slope at the top of the gully walls (i.e. the point where the relatively flat gully margins starts to slope into the gully). The perimeter coordinates have been acquired using a differential GPS total station (Topcon Hiper Lite +) in RTK (real Time Kinematic) mode with a horizontal accuracy of about 25 cm.
