The reconstruction of bed material yield and supply histories in gravel-bed streams
This paper details a basic method for estimation of both bed material yield and supply rates for a glaciated catchment. A simple regression relationship between discharge and erosion volume was used to predict the work done by the channel
in the absence of bed material supply from upstream. The bed material that must have been supplied from upstream between any 2 monitoring periods could then be determined by calculating the amont of sediment that had to be supplied to the reach between DTM

Modern research is showing clearly that there are many interactions between fluvial and aeolian processes in drylands. Aeolian accumulation patterns in time and space are strongly controlled by sediment supply from fluvial sources. Aeolian dust
deposition has significant impacts on slope processes, soil development and runoff-infiltration relations, which in turn affect sediment supply to fluvial systems.
erosion, and turbidity meters were used to determine suspended sediment transport. This research highlighted that for an upland catchment, bank erosion was an important supply of suspended sediment, and that for some flood events bank erosion can supply
, utilities, industrial land developers, and residential subdivisers. The success of the branch-plant strategy depended upon the ability of the local market to supply cheap land in central locations that met the requirements of mass-production processes.

The effects of road development were studied in a remote high-altitude Central Himalaya of India. Distribution of schools and postal services was not affected by this new road network, but health-care facilities, drinking water supplies, electricity
The Sacramento-San Joaquin Delta is both an important environmental resource and a critical link in the water supply system for California. The aim of this paper is to analyze the time series of Delta inflow for evidence of trend and annual regime
