Gully in arid climate.

A gully is a common landform in mountainous and hilly areas and is formed by surface erosion as a result of temporary water concentration (Vanacker et al. 2003).Among the various factors affecting gully systems, the watershed morphology is an important non-zonal factor that affects the rate, scale, and quantity of gully erosion (Zhang 2014).In turn, watershed morphology influences the process ...Feb 1, 1998 · The climate of this region may be described as seasonally dry.
