Geomorphological stability of sites for the long-term containment of uranium mining wastes in the seasonally wet Tropics, Northern Australia

and Pleistocene climatic and eustatic sea level changes. The youngest landforms have undergone extensive change over relatively recent periods and are unsuitable as sites for rehabilitated structures.

The role of landforms in ecological landscape structure

Conventional, genetic geomorphological mapping supplemented with morphometric data allows the application of these maps for the study of changes in geoecological pattern and land use. The example of the test area, delimited in the traditional wine

Landform replication experiments on quarried limestone rock slopes in the English Peak District

This paper describes the land surface changes resulting from limestone quarrying and considers the nature of landform evolution on quarried limestone rock slopes. This is followed by a description of a new technique known as restoration blasting

are all situated in the Eastern geomorphic region. In this region either the nature or the intensity of exogenic processes changes seasonally.

Environmental planning by geoecodynamic assessment in the Basin of Mexico

The changes in the relative magnitude of stream energy and resisting power during the last 20 000 yr until present day have been analysed. The balance of relative stream energy and resisting power assumes that the tectonic setting, climate

Natural conditions controlling earthflows occurrence in the Eden Canyon area (San Francisco Bay region, California)

morphological properties characterize earthflows of this type and how they change with time. The AA. studied the evolution of landslide activity in the Eden Canyon Area; the distribution of 1978-1986 landslides regarding ancient deposits, steepness of slope

Geomorphological aspects of the processes of desertification in the northeastern Rajasthan (India)

, salinization, reactivation of stabilized dunes and sandsheets and silting of river courses. The fluvial and aeolian agents become dynamically active once the protecting vegetation cover is partially or wholly removed, or changes in landuse are made
