Using sediment fingerprints to assess sediment-budget errors, North Halawa Valley, Oahu, Hawai, 1991-92
Aeolian features ; Aerosol ; Error ; Hawaii ; Methodology ; Sediment budget ; Suspended load ; Tropical zone ; Watershed
Reliable estimates of sediment-budget errors are important for interpreting sediment-budget results. The AA. modified the sediment fingerprinting approach to qualitatively evaluate compensating errors in an annual (1991) fine sediment budget
for the North Halawa Valley, a mountainous, forested drainage basin on the island of Oahu, during construction of a major highway. Sediment and aerosol budgets were developed using data collected in 1991. Differences between sediment-budget and aerosol-budget
imbalances provide a measure of compensating errors in the sediment budget.

An evaluation of two ten-year sediment budgets, Nahal Yael, Israel
Arid area ; Geomorphology ; Israel ; Negev ; Sediment budget ; Sediment load ; Suspended load ; Watershed
This paper compares a crude 10-year sediment budget published by Schick (1977) for Nahal Yael, a small hyper-arid drainage basin in the southern Negev Desert, with a second 10-year budget determined by more reliable methods. The comparison shows
that the original budget overestimated suspended sediment output by a factor of 4 and underestimated bed material output by a factor of 2. This paper emphasizes the difficulty of obtaining reliable estimates of sediment input to and output from a channel reach
Ireland's water budget - model validation and a greenhouse experiment
Climatic warming ; Drought ; Experimentation ; Greenhouse effect ; Impact ; Ireland ; Model ; Runoff ; Water budget ; Watershed ; Years 1970-79
In a previous paper (Mills, 2000) the A. described a simple water budget model that was applied to Ireland for the period 1961-90, but no model validation was attempted. In this paper the A. examines the relationship between the estimated surplus
water calculated for the catchment of the Shannon River with the measured discharge for that river. The close correspondence between these values suggests that the model is capable of estimating water budgets components at this scale. A simple climate
change experiment is presented that evaluates the impact of greenhouse warming on the water budget of this catchment. Discussion of the results.

The purpose of this study is to estimate and examine rudimentary sediments budgets for four river basins in the Piedmont physiographic province of North Carolina to determine the relative magnitude and importance of sediment storage.

Il ne s'agit pas des budgets comparés, mais leur seul rapprochement est plein d'enseignements pour qui s'intéresse et sans doute les géographes au premier chef à la politique économique de chacun des trois pays. (PmB).
The sediment budget of the Lillooet River Basin, British Columbia

This paper attempts to demonstrate the flexibility of a sediment budget methodology and the value of a step by step approach. The steps that are followed are: an explicit recognition of the time scale of integration of the budget; a recognition
Solute budgets and denudation rate estimates for a mid-wales catchment
Input-output budgets for thirteen solutes for a small moorland catchment in upland mid-wales show a net loss of all chemical elements from the catchment except hydrogen ion and inorganic nitrogen. These two are being assimilated by the catchment
. The solute budgets are affected by geochemical processes occurring within the catchment. A solutional denudation rate estimate of 2.9B is derived from the silicon budget and a denudation rate of 3.5 B from the loss of suspended sediment and bedload from
