amount and intensity of rainfall were both measured. The results show a high degree of variability, both in space and time. It is argued that the choice of scale is the most important decision to be made when devising an erosion study. The soil
The aim of this article is firstly, to review some of the relevant literature on both seed banks and methods for their study, and secondly, to emphasize the role of and need for further research within this area of biogeography.
The A. starts with the question of the atmospheric environment and quality of life and then studies the quality of climate and population response. He concludes with the implications of climate change for both environmental quality and quality
The A. distinguishes between implied dynamics (change is analysed through an examination of the parameter space of a static model) and absolute dynamics (time is explicitly included in the specification). This review charts the development of both
The current global warming controversy has sparked vigorous research activity, the ultimate aim of which is to undersatnd the effects of predicted climatic changes on both natural and managed ecosystems. Pointers from the past geological record
The objectives of this study are to describe the morphology and sedimentology of an alluvial fan, the Mount Goodenough North fan, in a permafrost region; and to interpret the processes responsible for the development of the fan, using both direct
This paper presents two approaches to using a data logger to interface between a flow recorder and a sampler, and provides a framework for the collection of high quality data from the field. Two hydrological systems were monitored; both
In this paper results are presented of a number of tumbling experiments designed to replicate conditions found in these high energy fluvial environments, both in terms of turbulent mixing and sediment characteristics. The results are compared
Diverse commentary from seven different authors on the idea of the buffalo commons which seeks to turn back the Northern Plains, espacially in the Dakotas, to grazing American bison for both conservational and economic reasons. - (DWG)
This paper intends to touch on the initial cause of motions in the fluids in gravity field, eg. the mantle and the atmosphere, and it is hoped that it will be helpful in solving the concerned basc problems both in geology and in meteorology.
The purpose of this paper is to clarify several aspects of the sedimentology of riffle-pool sequences, and to suggest how these both reflect and control riffle-pool stability in the presence of spatial differences in the turbulent near-bed flow
The research questions discussed in this article are central to the understanding of fluvial processes in both sand- and gravel-bedded rivers. Prominent research themes are identified. The first is the use of fractal concepts in the study of fluvial
Predicting the soil erosion response requires consideration of both direct and indirect influences of climate. Models of climate change provide input data about temperature, rainfall and wind strength, but the indirect influences of climate
, which would permit to trace the descending lithoflow using instrumental data. New prospects are outlined and importance of such studies (both from theoretical and practical points of view) is discussed, a well as their applicability to solving many
the low slopes and prevalence of sandy, permeable soils, there is reason to believe that soil erosion in the Coastal Plain is occurring at rates that are significant both from a geomorphic and an environmental management perspective.
