One means of quantifying fluvial erosion and the effects it has on our environment is by the examination of clasts within a fluvial environment and their characteristics, such as roundness and sphericity, lithology, and size and shape.
The lithology between the large (glacial: fluvial) and small (glacial : fluvial) data sets correlated in proving that the dominant rock present in both depositional units was limestone, as shown on the lithology histogram.
This is further exemplified by plotting the averages of the C/B ratios versus the B/A ratios of the clasts representing the glacial and fluvial units.

 Fluvial - Wikipedia, the free encyclopedia
The word fluvial is used in geography and earth science to refer to all topics related to flowing water.
Fluvial usually refers to rivers, streams and sometimes through flow, overland flow and percolation.
Fluvial may also refer to glaciers and oceans, though these are usually known as glacial, oceanic and coastal.

 QG&G Committee on Applied Fluvial Geomorphology
The integrated perspective of fluvial geomorphology, as well as the discipline’s rigorous understanding of the physical processes by which river channels are formed and maintained, and the importance of history and site-specific conditions, are critical to successful river management and restoration.
Fluvial geomorphologists explicitly recognize that a river is intimately connected to adjacent hillslopes, floodplains, riparian corridors, hyporheic and groundwater zones; to upstream and downstream portions of the drainage basin; to the history of river and watershed dynamics; and to other components of the environment, such as atmospheric and biological systems.
Fluvial geomorphologists are specifically trained to identify the relations between process and form along rivers, and to consider the possibility of thresholds, lag times, and complex response in river adjustment.

 ARS | Publication request: Modification of Phosphorus Export from a Catchment by Fluvial Sediment Phosphorus Inputs   (Site not responding. Last check: 2007-11-07)
The chemistry of phosphorus in fluvial sediments is the end result of many land use factors in a watershed, such as manure management, erosion control measures, and dominant topography, as well as how fast the stream or river flows.
This study examines if land use, fluvial sediment properties, and stream flow P are interdependent within a mixed land-use watershed in Pennsylvania, USA (WE-38), so that remedial strategies can be most effectively targeted to mitigate watershed P export.
Fluvial sediment P and sorptive properties varied among tributaries and flow regimes.

 Scope 35 - Scales and Global Change, Chapter 12, Variability of the Fluvial System in Space and Time
The prediction and postdiction of fluvial system behaviour is greatly complicated by this variability, and there are seven potential problems that must be considered in any attempt to extrapolate empirical relations in space and time.
The morphology and hydrology of the fluvial system is related to the controlling of independent variables that produce the morphologic and cascading characteristics of Zone 1 (Table 12.1) and which, in turn, significantly influence Zones 2 and 3.
The variability of a fluvial system under the influence of only three controls; stage of development, relief, and climate (variables 1,2,4) is summarized in Figure 12.2.

 The Use of Sediment Diversions in Fluvial Powered Wetland Restoration   (Site not responding. Last check: 2007-11-07)
When the fluvial forces predominate the deltaic region is considered to be active, ecosystems and land mass associated with coastal wetlands is increasing.
By incorporating fluvial diversions into the present systems sedimentation is heightened due to a decreased flow rate.
As the fluvial forces of sediment deposition become greater than that of erosion, the deltaic regions shift back from an abandoned state to an active one.

 Fluvial Geomorphologist - New England
Fluvial geomorphology is a science devoted to understanding how the natural setting and human land use in a watershed determine the shape of the river channel.
A fluvial geomorphologist seeks to predict what physical changes will occur to a stream channel in response to alterations in watershed conditions; and, in turn, how these changes will impact human infrastructure and fish habitat.
Although the science of fluvial geomorphology is decades old, its widespread application in watershed studies is relatively recent.

 Sun.Star Baguio - BFF fluvial committee bares early entrants
Of the four categories open to the public two weeks ago, the Burnham Lake boat concessionaires’ category remains as the grouping to be the most participated in, with 12 fluvial floats expected to join and vie for trophies and cash prizes amounting to P15,000, P10,000 and P5,000, respectively.
According to City Assessor Estrellita Tano, this year’s fluvial parade committee chairperson, a total of P155,000 in cash and other surprises await participants to this colorful lake parade and other contests slated on February 13 and 14 this year.
She said this amount was earmarked by the city government for competitions in the fluvial parade which were divided into four categories, and 20 other contests and races that were scheduled for the two-day occasion.

 Fluvial Geomorphology and Riparian Systems   (Site not responding. Last check: 2007-11-07)
The monitoring program for fluvial geomorphology and riparian issues should consist of periodic aerial photography of all significant streams in the CALFED area of concern, supplemented by field studies at selected sites and a miscellany of other activities.
For fluvial geomorphology, we tentatively recommend that about 40 to 50 long-term sites should be established over the area of concern; we hope to provide more specific recommendations for the final report.
A second and related concept of particular importance for fluvial and riparian systems is the intermediate disturbance hypothesis (Connell 1978, Pickett and White 1985), which states as a generality that biological diversity peaks in environments with an intermediate level of disturbance.

 Stream table modeling of fluvial systems.
Using a stream table in the department of Geography and Geology at the University of Nebraska we have been able to produce the equivalent of meander bends, mass wasting of cut banks, flood plain development, terraces, alluvial fan/delta progradation, headward retreat and sorting among other features and processes.
As the channels lengthen, cutting back into the sand body (a process known as headward retreat), in the stream table it is common that one of the channels is abandoned, as the other captures more water, cuts down and lengthens.
They reinforce the idea that fluvial systems are dynamic, and that channels migrate and switch with time, and that other processes such as mass wasting can be associated with this behavior.
