Suspended sediment load was analyzed in a small, high-gradient stream of the Eastern Italian Alps which was instrumented to measure discharge and sediment transport. The ratio of suspended to total sediment yield and the relations between sediment
sources. An analysis of grain size has shown that erosion areas on hillslopes were the main sources of suspendedload.
concentration and water discharge were analyzed for 7 floods which occurred from 1991 to 1996 in summer and autumn. Different patterns of hysteresis in relation between suspended sediment and discharge were related to types and locations of active sediment
Sediment yield and spurious correlation. Toward a better portrayal of the annual suspended-sediment load of rivers
Two alternative methods for portraying the annual suspended-sediment load of a river are suggested. One method consists of plotting supended-sediment load (tons per year) against distance downstream. Such plots indicate that annual suspended
-sediment load does not necessarily have a linear relationship with distance. The second method consists of plotting annual suspended-sediment load against drainage-basin area. Both methods more accurately portray fundamental relations between annual
sediment load and drainage-basin characteristics than does the yield-area relation because spurious correlation is avoided.

Bibliography ; Forecast ; Methodology ; Model ; Statistics ; Suspendedload ; Water quality ; Watershed ; Years 2000-2009
This paper synthesizes a variety of methods adopted in suspended sediment monitoring, estimation and modelling for understanding sediment transport processes and determining the suspended sediment load. Methods for sediment monitoring are described
at the watershed scale. The paper ends with the discussion of future developments in suspended sediment studies at the watershed scale.

Use the notion of fractal theory to obtain important information regarding the possibility of temporal transformation of sediment load data is the subject of this study. As a first step, daily suspended sediment load data observed in the Mississippi
behaviour in the suspended sediment load data, suggesting the possibility of transformation of data from one scale to another using a multi-dimensional model.
Suspended sediment load transport in the Mississippi River basin at St. Louis : temporal scaling and nonlinear determinism
Carrying capacity ; Correlation ; Determinism ; Mississippi ; Missouri ; Model ; Statistics ; Stream ; Suspendedload ; United States of America
This study investigates the dynamic behaviour of suspended sediment load transport at different temporal scales in the Mississippi River basin. Data corresponding to 5 successively doubled temporal scales (i.e. daily, two-day, four day, eight day
, and 16-day) from the St. Louis gauging station in Missouri are analyzed. The investigation is focused on identifying possible low-dimensional deterministic behavior in the suspended sediment load transport dynamics, with an aim towards reduction in model

Suspendedload is an important component of sediment transport in the surf zone. This study investigates the relationships between causative wave and current dynamics and resultant characteristics and distributions of suspended sediment in the surf

This study deals with magnitudes and processes of suspended sediment transport in Tarfalajåkk, the primary stream in the Tarfala drainage basin. In addition, an attempt to simulate suspendedload was made by means of a simple regression model based
of the current water erosion. The regions with higher erosive wash were specified by means of suspended sediment and dissolved load. The sources of the point pollution were taken into account. - (MS)
The results of four-year measurement of suspended sediments in the Holedeč profile at the Blšanka river in the NW Bohemia. The main attention is paid to the typology of the individual regime situation and to geochemical analysis of suspended
The aim of this study was to assess the impact of climatic change on sediment transport in the river Rhine, and on the deposition of suspended sediment on the embanked floodplains in the Netherlands. - (AGD)
Turbidity and suspended solids variations downstream of a regulating reservoir
A controlled reservoir release from Llyn Celyn to the Afon Tryweryn, Wales, U.K., has been used to study suspendedload and turbidity variations. Turbidity was monitored continuously at two sites and 235 suspended solid samples were obtained
Measurements of suspended and dissolved loads in this watershed suggest that deforestation and agricultural activities increase the rates of erosion by a factor of five to ten. - (DWG)
In this study, field settling velocities of the suspended sediment have been measured during two tidal periods, in Ho Bugt, on October 17, 1989 and July 24, 1990. During both periods, the current velocity, salinity, water temperature and suspended
sediment concentration were measured together with the field settling velocities of the fine-grained suspended sediment. Discussion of the results and study of the flocculation process.
Evaluation of suspendedload changes using AnnAGNPS and SWAT semi-empirical erosion models

. Both models were calibrated using the first 5 years of data, and then validated using the second 5 years of daily discharge and suspended sediment yield values. According to both models, suspended sediment load was reduced after the land use changes.

This paper investigates the relatonship between bank erosion and suspended sediment dynamics at the annual, monthly and event timescales within the upper River Severn. Manual erosion pins and photo-electronic erosion pins were used to estimate bank
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
