The world’s arid lands are some of the most beautiful landscapes on Earth, and their paucity of vegetation often makes it possible to see landforms and structures with great clarity (Figure 1.1). In addition, they have many characteristics both in terms of landforms and geomorphological processes that render them different from other major environments (see, for example, Laity, 2008; Parsons an...

PRIME Lab has a multidisciplinary external research program with projects in geomorphology, hydrology, ocean science, planetary science, environmental science and biology. Introduction PRIME Lab is a national AMS facility for measurement of the long lived cosmogenic nuclides Be, C, Al, Cl, Ca, and I [1]. Since its inception in 1991 we have chemically processed over 2000 samples and have measure...

Community convergence across biogeographically distinct regions suggests the existence of key, repeated, evolutionary mechanisms relating community characteristics to the environment. However, convergence studies at the community level often involve only qualitative comparisons of the environment and may fail to identify which environmental variables drive community structure. We tested the hyp...

In recent times, the issues of geodiversity assessment and mapping have been subject great attention, many evaluation methodologies, either quantitative or qualitative, developed. this research, a first in Liguria region has carried out, according to method based on spatial analysis techniques implemented GIS environment. This considers four diversity indices obtained by grid analysis, relevant...

Modern marine seismic reflection data have allowed for the study of morphology submarine channels in a 3D perspective. This presents quantitative analysis continental slope channel complexes within Canterbury Basin (New Zealand). It aims to characterize and facies better understand their formative sedimentary processes, paleoenvironment, petroleum prospectivity. Submarine morphometric parameter...

A major emphasis in geomorphology over the past several decades has been on the development of quantitative physiographic methods to describe the evolution and behavior of surface drainage networks. The quantitative analysis of morphometric parameters is found to be of immense utility in river basin evaluation. The influence of drainage morphometry is very significant in understanding the landf...

In recent years, various process-based models for the evolution of regional landform systems have been developed (Coulthard, 2001). Quantitative models have considerable use in applied geomorphology, but also represent a good means we have for testing and developing theoretical models. Nevertheless, there remains a considerable gap between the detailed quantitative representation of individual ...
