Although both areas have a semi-arid climate, the more humid conditions in Guadix allow a higher vegetation cover providing a higher erosion resistance. 5.3. Multiple regressionHigher richness was found in the moister crust habitats (gully and moraine) than the drier non-crust habitats (near gully and slope) for both 16S (p < 0.003) and 18S (p < 0.001) (Figure 5). However, between the dry non-crust habitats, the near gully had significantly greater richness than the slope for both 16S (p < 0.001) and 18S (p < 0.001 ... Gully erosion covers more area in the arid climate than humid one. Human impact, intensive and short period rainfall with soil chemical characteristics helped gully erosion to develop. In the arid climate, the gullies have dendretic general view plan. They are also longer and denser. It implies the surface runoff production by uplands. Gully erosion is a worldwide phenomenon expressed by a wide range of incised landforms tightly correlated. The commonly used solution in the northern Negev is based on damming the gully with perpendicular check dams. ...

Gulch and gully are two words that are often used interchangeably, but they actually have different meanings. A gulch is a narrow and steep-sided ravine that is usually dry, while a gully is a water-worn ravine that is usually wider and deeper than a gulch. One common mistake people make is using gulch to describe a gully.
