Particle size distribution and its influence on the rheology and sensitivity of Leda clay in Our geographic mosaic: research essays in honour of G.C. Merrill.
subaerial flow type processes. Identification techniques from various fields (morphometry, rheology, geomorphology, sedimentology) are reviewed. Recent accounts of flow processes as part of a continuum of processes as opposed to belonging to distinct
The depth distribution of earthquakes in Belgium is studied to obtain informations about the actual rheology of the crust. The quality and the reliability of the informations are dependent of their ancientness and the earthquakes location
Le point sur les dernières recherches (2002-2003) concernant les glaciers et la glaciologie : datation isotopique, sédimentologie glaciaire, rhéologie, dynamique glaciaire, paléoglaciations, localisation de lacs glaciaires sous la calotte
Etude de la confluence de 2 grands glaciers rocheux dans le sud-ouest du Yukon. La variabilité des sédiments et du contenu en glace, ainsi que la combinaison des rides de compression et de masses chevauchantes, indiquent une rhéologie de surface
This paper examines how frost-cracking events are related to variations in air and ground temperatures. The implications of the results for ice-wedge dynamics, frost cracking processes and frozen ground rheology are also discussed. The study site
model is presented, using the theory of uniformly progressive flow and incorporating zoned longitudinal variation in rheology. It is shown that non-homogeneity can cause very significant magnification of the peak discharge, depending on the slope angle
. A rafting mechanism in which blocks of roots from individual trees interact with those of neighbouring trees to retard surface movement is used to explain deformation profiles of forested earthflows. The rheology of earthflow materials is changed
and bedload should also be considered as a granular phenomenon. The AA. review progress made recently in the study of granular flows, especially on segregation and rheology, that better illuminates the nature of bedload. Mutual study of these phenomena may
