This erodibility index is the first estimate of sediment production potential of different rock types aimed at regional to global scale application. The erodibility index presented here can help improve our understanding of global erosion and landscape evolution. A new lithology erodibility layer, the ...
The for- mation of stable soil organic carbon compounds depends on the type of vegetation, soil and landscape characteristics of localities, and methods of field man- agement. In a broad sense, the type, productivity, and frequency of particular land uses influence the general balance of ...
The páramo is jointly with puna, Andean forests, inter-Andean valleys, and mountainous deserts, one of the five distinct landscape units found in the tropical Andes region based on altitude and average temperature (Cuesta et al. 2009). This unique ecosystem spans across the Andean region of we...
Initially, the agates were found scattered loose over the landscape and were readily harvested in quantity. Today, surface collecting is no longer prolific, so these agates are collected from shallow diggings in the cold agate fields in Mendoza province, Argentina. Sagenite Agate Golden Sagenite ...

18 investigated the relationship between some characteristics of landscape including slope and aspect with soil organic carbon values. They showed that the soil organic carbon in the topsoil was highest in north oriented aspect soils (13.25 g kg−1), as compared with all other aspects. In ...

The unique terrain characteristics of a particular landscape are derived from DEM, which are responsible for initiation and development of ephemeral gullies. As the topographic features of an area significantly influences on the erosive power of the water flow, it is an important task the extraction...
or the development of activities affecting the landscape (e.g., urbanization) (Oliveira et al.2015b). In the 1983 landslide event (Table1), 173 slides were mapped over an area of 130,750 m2(0.12% of the study area). Shallow rotational slides were the dominant type (98 cases), ...
