Geomorphic dynamics of gullied developed in Sandy slopes of Central Spain

Gullies developed on sandy lithologies are scarce. Such landforms have developed in the sandy deposits of the Cretaceous ‘Utrillas’ facies within the Segovia province of Central Spain. They appear at the slopes of a group of mesas and cuestas located at the edge of the northern piedmont of the Guada...
