Grain-size analysis by laser diffractometry : comparison with the sieve-pipette method
Clay mineral ; Grain size distribution ; Methodology ; Soil ; Soil properties ; Soil science ; X-ray diffraction analysis
Results of a traditional sedimentation technique for grain-size analysis (the sieve-pipette method) were compared with those of a laser diffraction grain-size analyser, the Coulter LS-100. Milled quartz samples and silty soil samples were used
Combined analysis of digital terrain models and remotely sensed data in landscape investigations
This article presents a review of the combined analysis of digital terrain models (DTMs) and remotely sensed data in landscape investigations. The utilization of remotely sensed data with DTMs has become an important trend in geomatics in the past
Geomorphological and sedimentological analysis of a catastrophic flash flood in the Arás drainage basin (Central Pyrenees, Spain)
in the Betés subbasin. Two stages in the development of the flood have been differentiated from the sedimentological and morphological analysis of the flooded fan lobe : peak discharge and discharge decline.
The influence of bank strength on channel geometry : an integrated analysis of some observations

Bank strength exerts a significant influence on river channel geometry. In order to undertake an integrated analysis of wide-ranging field observations, this study applies a recently developed multivariate model of channel geometry. When the banks

Integrated toposequence analysis at the confluence zone of the River Ebonyi headwater catchment (south eastern Nigeria)
Integrated Toposequence Analysis (ITA) as presented in this paper provides a methodology that combines conventional bio-physical and participatory research techniques in the study of land use systems and land resource evaluation along toposequences
The basic concept of the elaboration was a geomorphological analysis to be carried out jointly with that of its framing river valleys (Hernád, Bódva) constituting the relief boundary. The general evolution of the Hernád Valley : the article provides
an analysis of the present-day geomorphological and economic role of the high bluffs suggesting a substantial part played by slumps in their ongoing formation, which is a specific feature in the area of the North Hungarian Mountains. A similar analysis
