THE EFFECT OF GULLY EROSION ON THE FORMATION OF SCREES AND ROCK FALLS IN THE SECTOR OF ZABALA, PICHINCHA PROVINCE, ECUADOR

A study was conducted on the effect of the number and length of gullies on the development of rock falls and screes on the eastern slope near the city of Quito in the Equatorial Andes. It has been established that gullies with a length of more than 400 m have the most significant effect on the formation of rock falls and screes at the foot of the slope. The total number of gullies is not a significant factor in the development of these geomorphological processes.
