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.
The distributed sediment budget model and watershed management in the Paleozoic Plateau of the Upper Midwestern United States
Floodplain ; Land use ; Model ; River management ; Sediment budget ; Soil erosion ; United States ; Watershed ; Wisconsin
The distributed sediment budget model describes the complex sediment storage fluxes of three basin zones (tributaries, upper main valley and lower main valley) in the Paleozoic Plateau of the Midwest and is therefore useful for purposes of watershed
A comparison of moisture scalars and water budget methods to assess vegetation-site relationships
Beech ; Biogeography ; Digital elevation model ; Habitat ; Index ; Methodology ; Ohio ; Soil moisture ; United States of America ; Vegetation ; Water budget
This study compares 3 approaches, a water-budget approach, and field-based and map-based moisture scalars, in their ability to predict the occurrence of a single species, American beech (Fagus grandifolia), observed in 102, 0.04 ha plots in SE Ohio
. It concludes that a water-budget approach is applicable to a wide range of studies exploring vegetation-site linkages, and in terms of global change, this approach offers the additional benefit of being a dynamic model.

Many land-management decisions would be aided by an understanding of the current sediment production and transport regime in a watershed and of the likely effects of planned land use on that regime. Sediment budgeting can provide this information

The role of impoundments in the sediment budget of the conterminous United States
Cultivated land ; Dam ; Hydraulic works ; Pond ; Reservoir ; Sediment budget ; Soil erosion ; United States of America ; Watershed
The AA. use the term impoundments to refer to artificial water bodies regardless of size (reservoirs and ponds). They examine the role of these small impoundments in the sediment budget, at the sub-continental scale. Specifically, they estimate
the total volume of sedimentation occurring in small impoundments and compare that quantity to other components of the fluvial sediment budget for the conterminous U.S. It is clear that most sedimentation is now taking place in subaqueous rather than
The fate of eroded soil: sediment sinks and sediment budgets of agrarian landscapes in southern Minnesota, 1851-1988

This paper examines the fate of eroded soil by tracing the distribution of eroded sediment and constructing the sediment budgets of three medium-size drainage basins in southern Minnesota. This research attempts to improve our understanding

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

The long-term studies of water and chemical budgets in the Hubbard Brook watershed, White Mountains, New Hampshire, have assumed that the underlying bedrock is watertight and that all of the liquid water discharged from the experimental subcatchment

Focusing on enterprise-state relations, the AA. investigate governmental involvement in corporate bodies, soft budgets, subsidies, state purchases, lobbying, and dispute resolution, and present evidence on how such relations vary with ownership
and level of government. Discussion and analysis cover the effects of devolution of state supervisory power on enterprise-state relations.
Developing a new stream metric for comparing stream function using a bank–floodplain sediment budget : a case study of three Piedmont streams
Carrying capacity ; Comparative study ; Floodplain ; Piedmont ; Sediment budget ; Sediment load ; Stream ; Suspended load ; United States of America ; Virginia
A bank and floodplain sediment budget was created for 3 Piedmont streams tributary to the Chesapeake Bay. The watersheds of each stream varied in land use from urban (Difficult Run) to urbanizing (Little Conestoga Creek) to agricultural (Linganore
Creek). The aim of the study was to determine the relation between geomorphic parameters and sediment dynamics and to develop a floodplain trapping metric for comparing streams with variable characteristics. Net site sediment budgets were best explained
by gradient at Difficult Run, floodplain width at Little Conestoga Creek, and the relation of channel cross-sectional area to floodplain width at Linganore Creek. A correlation for all streams indicated that net site sediment budget was best explained
by relative floodplain width (ratio of channel width to floodplain width). A new geomorphic metric, the floodplain trapping factor, was used to compare sediment budgets between streams with differing suspended sediment yields. This trapping factor promises
