to the early Holocene, may be due to climatic, vegetation, or other differences between the fan environments. During the late Pleistocene, both fan systems terminated in pluvial lakes, Lake Lahontan in Nevada and Lake Mojave in California. In both cases, dated
Using both original laboratory and field data, and data from the literature, this paper examines the question of the apparent variation of resistance coefficients in relation to flow velocity, even in the absence of interaction between hydraulics
and resulting erosional bed forms. Resistance equations are first assessed as to their ability to describe flow velocity. A new methodology is illustrated which gives good agreement between estimated and measured flow velocity for both well-inundated sheet
In studying the origin and evolution of landscape, various scales are used both in space and time. The A. suggests distinguishing the following effective time scales of landform evolution : formative extreme events and secular processes, clusterings
: way to destinity (planation), continuous adjustment to new conditions, coexistence of diverse forms controlled both by tectonic and climatic factors as well as by lithology.
Aspects of the interrelationships of attitudes and behaviour as illustrated by a longitudinal study of British adults : 2. Predicting voting intention, strength of party identification, and change in both
The well known sulphureous springs are reported both in regional and national geological maps, but detailed studies have been rarely carried out. In this paper the AA. describe the sulphureous waters on the basis of the hydrochemical facies
the Quaternary period, covered by windblown sand in the form of linear desert dunes. These findings have implications for Pleistocene refugia in Africa and may explain both the relative paucity and high degree of endemism observed among African biota.
This paper is both a literature review and a precursor to a research agenda focusing on a geoarchaeological analysis of the tracks within a GIS reconstruction of the Maltese palaeo-landscape. Conjectures on the origin, function and date
with transition from democratic system to a totalitarian one like in Czechoslovakia during the late 1940s and 1950s. In the post-totalitarian Czechoslovakia, the role of both tendencies has been associated with the change towards a democratic system. - (MS)
for the measurement of both distributions and consequent loss of material from the bed. It is concluded that saltating sand grains can rupture weak crusts under even moderate wind conditions, and that the rate of erosion will depend on the shape of the distribution
The examples, taken in weathered andesitic pyroclasts occurring in the northern and northeastern part of the island of Basse Terre (Guadeloupe), studied here highlight the occurrence of different clay minerals and their spatial variability both
This article is an introduction to the Fennia volume dedicated to scientific, physical and biogeographical studies concerning 2 adjoining National Parks on both sides of the Fenno-Russian border : Oulanka and Paanajärvi. The papers in the volume
This paper gives a review of the main physical features of the Kuusamo Uplands and the Oulanka-Paanajärvi area. Then, the course of the highest shoreline is presented for both sides of the Kuusamo watershed. This is the first up-to-date illustration
Gauging data are available from numerous streams throughout Australia, and these data provide a basis for historical analysis of geomorphic change in stream channels in response to both natural phenomena and human activities. The AA. present
Different mountain shapes in sedimentary sequences in the Canadian Rockies were enhanced by glacial erosion and have been modified postglacially by gravity-driven slope processes. Slope modification by both glacial erosion and postglaciation
A dynamic simulation model for maize growth and development, MZMOD, was used to assess the potential implication of the changes in both climatic means and variability, and the impacts of crop management in changing climate on maize production
In the approach presented in this paper, the geometric reconstruction of urban areas is based on height data from airborne laser scanning and 2D GIS, which provides the ground plan geometry of buildings. Both data sources are used to estimate
The aim of this paper is to model the sensitive of drainage systems to increased regional gradient at both the river-network scale and gully-system scale. The research is applied to a semi-arid region experiencing extensional tectonic activity
