The quantitative revolution in the natural sciences has brought about new trends in geomorphology too. Experimentalgeomorphology is the discipline which establishes relationships between landforms, processes and materials under controlled
Dissatisfied with previous definitions, author presents his opinion that experimentalgeomorphology reveals relationships, and regularities between landforms, geomorphic processes and the materials involved in the processes on the basis
Review and prospect of experimental studies on fluvial geomorphology in China

As a branch of geomorphology, the fluvial dynamic geomorphology is a marginal science among fluid dynamics, sediment mechanics and fluvial geomorphology. With physical modelling by similarity based on Newtonian mechanics, and principle of the same
effect but different structure based on systematic theory, it is possible to study properties, formation and processes in fluvial dynamic geomorphology. A new research method, which is a combination of mathematical simulation by computer with physical
An experimental form of mapping has been tried, initially at 1 :5 000 000 scale covering the whole of Australia and then at 1 : 1 000 000 scale over the Kalgoorlie area of SE Western Australia. With appropriate interpretation the Kalgoorlie Regolith
Terrain Map provides a geomorphological basis for mineral exploration.
This paper describes the experimental use of correspondence analysis to test the success of the geomorphic approach used. The survey involved the direct mapping of Soil Taxonomy subgroups and phases of subgroups within delineated geomorphic units

Automated digital photogrammetry was used to produce digital elevation models of experimental model landscapes under controlled laboratory conditions as part of a series of rainfall erosion experiments looking at the evolution of landforms
in response to erosion. The method allowed the elevations of the experimental landscapes to be studied in great detail on a regular grid digital terrain map. Digital photogrammetry produced elevation data at a resolution of 6 mm with a standard deviation
of 2.0 mm over an experimental catchment relief of approximately 200 mm; this resolution is considerably better than that achievable by conventional manual photogrammetry.

Soil erosion in developing countries: where geomorphology fears to tread!

Geomorphology claims an expertise in the study of soil erosion and the development of conservation solutions. As applied scientists, geomorphologists could assist their cause greatly by providing quality information on erosion process rates
and their impact in a timely and applicable way. Descrpitive and predictive models hold scope for extending geomorphological information beyond empirical confines. Examples throughout the paper are drawn from projects in South Asia, South America and southern
This initial laboratory study was carried out in a small flume, without rainfall, using sieved sand, and was designed primarily to test experimental methodology and to provide initial information on selective transport and deposition on smooth

Fire in the natural environment is a widespread agent of geomorphological and biological change. Temperatures can exceed 1000°C. Laboratory simulation studies have established that temperature changes which are representative of natural fires affect
Some reflections on modelling hillslope processes in Geomorphological models. Theoretical and empirical aspects.
The AA. believe that in modelling hillslope processes, a combination of both theoretical and experimental approaches is needed as illustrated by several examples from the Louven laboratory.
