This paper examines the characteristics of small offset streams in Japan, through the analysis of planform channel course geometry and longitudinal profiles measured in the field. Some configurations characteristic to the deformation types still
remain in their longitudinal profiles with various degrees of fluvial adjustment as long as the fault activity continues.

The longitudinal profiles of 24 rivers of 3rd to 5th order have been analyzed in order to recognize the regional tectonic differentiation pattern of the Ardenne, a Paleozoic massif of NW Europe. Data collected exclusively from 1/25,000 topographic
maps were used to define a set of parameters related to the geometry of the profile and proxies for river bedload and drainage area. The combined analysis of all the parameters confirms the current uplift of the NE Ardenne and points to a subsidence
Migration and residential social change : a longitudinalanalysis of migration flows into, out, of, and within in Regards sur la mobilité socio-spatiale.
This paper analyses the role of migration in residential social change in London during the intercensal 1971-81 using data from the 1 % Longitudinal Survey. It compares the socio-economic composition of out-migrants from, and in-migrants to London

The purpose of this study is to consider the changes in commuting flow in the three major metropolitan areas in Japan in terms of cohort size and female labour using longitudinal data on residential, occupational and family careers and cohort
This paper presents an effort to link a field-based study with surface exposure dating techniques to understand river longitudinal profile evolution. The study was aimed at improving the understanding of the rates and processes governing bedrock

Coarse debris flows develop surges with distinct longitudinal sorting. Although highly unsteady, such flow often appears to attain a steady-state condition, moving over long distances with approximately constant velocity and maximum depth. A simple
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

Using terrace mapping, sediment composition, C 14 and thermoluminescence dating, and morphostructural analysis, this paper presents the composed longitudinal profile and the structural analysis of the lower course of the Ivinhema River. The tectonic
model of the study area constitutes a sequence of NW tilting fault-blocks formed from antithetic faults that control channel sinuosity, longitudinal profile, floodplain distribution and valley asymmetry. The present river channel has a higher sinuosity

is assumed to be determined by the basal shear stress. A stability analysis shows that the short-scale transverse perturbations are stable while the long-wave transverse perturbations are unstable. The analysis also shows that the longitudinal perturbations
Trough valley with stepped longitudinal profils and corries are common features of glaciated terrain. An ice sheet and glacier are modelled as a layer of a very viscous incompressible fluid flowing down an inclined bed. The rate of erosion
