Rock-Mantled Slopes. These processes are not only important in terms of understanding hillslope form but because they give rise to a variety of hydrologic and geomorphic phenomena such as flash flooding, extreme soil erosion, and hazardous debris flows.

Arthropathy

Channel Processes, Evolution, and Historyal basis of the subject at the end of the 20th century still bears a heavy imprint from the American source. In the Old World, only the Israelis, under A. Schick, have been able to maintain such a strong contribution to desert fluvial geomorphology.

蒸发

Pediments in Arid Environments Gran Sabana of south-east Venezuela, a broadly upwarped region of gently dipping early Proterozoic strata, pediments comprise the floors of broad subsequent valleys developed within less resistant parts of the section (Dohrenwend .. 1994b).

行业

Geomorphology of Desert Environmentstable measure of aridity upon which to base a definition of desert areas has not been straightforward, and several attempts based upon a variety of geomorphic, climatic, and/or vegetational indices of aridity have been made to identify the world distribution of deserts.

Aridic Soils, Patterned Ground, and Desert Pavementstrongly influenced by the physical and chemical characteristics of the underlying soils. As a result, the evolution of a diversity of desert landforms is either directly or indirectly linked to pedogenic processes.

The aim is not to be exhaustive or comprehensive, but hopefully to question some traditionally held views and stimulate future research.
