The AA. investigated the alluvial stratigraphy, soils, and geomorphology along a section of the lower Little Cedar River to aid in understanding the processes forming this landform region. They used terrace- and floodplain surface height above

The AA. describe a case study conducted at Nuevo San Juan Parangaricutiro, an indigenous forest community in the Paricutin area, in Michoacan. Specifically, they discuss the contribution of geomorphologic mapping (coupled with landscape knowledge
The AA. report the results of glacial geomorphological mapping of the Strait of Magellan and Bahía Inútil. The aims are to determine the pattern and process of deglaciation during the last glacial-interglacial transition and to provide a firm
geomorphological basis for the interpretation of radiocarbon, cosmogenic isotope and amino acid dates for the timing of deglaciation. The mapping shows that it is possible to make a clear weathering and morphological distinction between last glaciation and older
Geomorphological evidence of the influence of pre-volcanic basement structure on emplacement and deformation of vocanic edifices at the Cofre de Perote-Pico de Orizaba chain and implications for avalanche generation
Since 1989 slope movements of tectonic origin have been monitered in this three pseudocarst localities in Polická pánev - basin. Presence of movements of tectonic origin hasn't been proved. For further interpretation a small-scale geomorphological
The aim of this study is to identify ice-flow instability, e.g., surge-related events, for a retreating glacier with unknown surge record. The AA. compare the landform assemblage from the foreground of Elisebreen with hypothesized geomorphological
criteria derived from observations of surging glaciers elsewhere and find that ice-flow instability can be inferred when geomorphological criteria are combined with sedimentological data.

This paper examines why the definition of a river is an important and ongoing management issue, and outlines the development of legal definitions of river. Finally, the role of fluvial geomorphology is discussed with respect to the definition
