| Arid and semi-arid landscapes often contain unique geomorphologic features. |
| We observed that both geomorphologic structure and depth influence presence of biocenosis. |
| Through such methods, especially when combined with geomorphologic techniques, it is possible to demonstrate that at no time in the past were all areas irrigated. |
| Definition and classification of mountain areas on the basis of their altitude and of the climate, geomorphologic, economic and infrastructure conditions at different locations. |
| The geomorphologic evolution mechanism of gullied catchments can be explained as a function of geomorphologic indicators of inter-gullied and gullied land characteristics. |
| No information is currently available on geomorphologic feature types in protected areas or by ecozone. |
