The investigation of linear erosion forms was carried out at the city of Quito (Equatorial Andes). The study was aimed to define the correlation between rill forms with different length parameters in the key-site area located nearby Zabala. It is stated that the rill forms with the length up to 50 m (58%) prevail. The gullies with the length of more than 200 m make 9% of all rill forms. Nevertheless, these gullies, as a rule, create main channels that provoke the formation of multiple side forms in the process of regressive erosion. The further development of the linear erosion causes the dissection of the investigated area that increases the risk for landslide developments.
