Stereophotogrammetry of archive data and topographic approaches to debris-flow torrent measurements : calculation of channel-sediment states and a partial sediment budget for Manival torrent (Isère, France)
in the channel is presented. This sampling method was optimized with respect to the specific debris-flow torrent morphology. Secondly, measurements were made on the Manival torrent at 12 different dates from 1963 to 2000. Thirdly, partial sediment budgets
and erosion-rate estimates for the same time period in the Manival torrent are discussed.
Ten pairs of Fish Eagles, taken among a dense population in Uganda, were followed at the end of the breeding season to compare the time and energy budgets of breeding and non breeding adults. The food consumption of adults with young is higher than

of sediment units show an important increase in alluvial deposition from medieval times onwards, indicating the important influence of agricultural activities that developed from that period. Sediment budgets for the various tributary catchments provide
A Holocene sediment budget was constructed for the Dijle catchment in the Belgian loess belt, in order to understand long-term sediment dynamics. Hillslope sediment redistribution was calculated using soil profile information from 809 soil augerings
, which was exprapolated to the entire catchment using morphometric classes. As large parts of the forests within the catchment prove to have undergone little or no erosion since medieval times, a correction was applied for the presence of forests. Dating
of the last great Pleistocene glaciation 18,000 years ago show that the form of the earth's surface at that time was considerably different to its present form. The results show a difference between the earth's radiation budget 18,000 years ago
In this essay, the influence of albedo on the radiation balance is investigated. If an interaction between the form of the earth's surface and the radiation budget exists, this should be quantifiable by estimating the albedo value. Reconstructions

Late Pleistocene climate and water budget of the South American Altiplano
Geomorphic evidence from the Peruvian-Bolivian Altiplano indicates that during episodes prior to 28,000 and around 12,500-11,000 yr BP lakes covered an area about six and four times as large as present, respectively. Within the constraints
of the heat and water budget, model calculations are used to estimate the precipitation rate that would allow hydrologic equilibrium. Field evidence suggests that the episodes of enlarged lakes on the Altiplano may have preceded or coincided with periods

Sediment budget data from an 18-month topographic survey were analysed with data from brief experiments on wind parameters, beach moisture contents, bedforms and sand mobilization in order to monitor conditions and patterns of embryo dune
development over a flat 150-1000 m wide accreting upper beach, on the North Sea coast of France, near Calais. Net dune development over time depends on sustained strong winds and their orientation.
Problems are discussed which result from the reconstruction of the radiation budget of the earth's surface of postglacial times in Middle Europa. Data of measured net radiation components of a grass surface and of a pine stand are presented
. The importance of cloud amount on the budget components is referred to.

. Despite such fluctuations, there are gradual declines of total carbon content of topsoil and soil depth to bedrock, since the time of forest clearance. Results have application to large-scale sediment budget and water quality models and to the New Zealand
on selected soil properties at larger spatial scales and over longer time periods. Research was conducted within an area of pastoral soft-rock Tertiary hill country in the North Island of New Zealand. Integrating landslide densities with soil recovery data
demonstrates that the average value of a soil property fluctuates in a saw-tooth fashion through time with the overall shape of the curve controlled by the frequency of landslide inducing storm events and recovery rate of the soil property between events
