    In practice, river type classification for ELOHA tends to be iterative or to use pre-existing classes. Based on 9 case studies, Kendy et al () strongly recommend developing a river classification system in concert with flow-ecology analysis, rather than a priori, and note that starting with a simple, existing classification system helps build trust and speed the overall process.

This book provides a comprehensive overview of recent developments in river channel management, clearly illustrating why an understanding of fluvial geomorphology is vital in channel preservation, environmentally sensitive design and the restoration of degraded river by: channel form, flows and sediments - of endogenous ephemeral rivers in deserts; water, a significant agent - of erosion in arid lands; desert streams, differing from their perennial counterparts - propagation of flood waves; flash flood hydrograph; ephemeral river channel geometry - desert streams, and their great width; fluvial sediment transport.

FRESH SURFACE WATER – River Morphology and Channel Processes - Iware Matsuda through channel processes. The main channel processes or fluvial processes are erosion, transportation and sedimentation.

Erosion predominates in the upper reach area of a drainage basin, and valleys composed of channels and slopes are formed.

Bankfull discharge is the flow that transports the majority of a stream's sediment load over time and thereby forms and maintains the channel. Any flow that exceeds the stage of the bankfull flow will move onto the floodplain; therefore bankfull stage is consid­ ered the incipient point of flooding.

Bed material generally forms the coarser part of the sediment load a channel is able to transport and constitutes the bed and lower banks of the stream. The wash material is the finer part of the sediment load and is generally transported long distances, being deposited in the upper banks and on the floodplain.

Banks are the sides of a river or stream between which the water normally flows. bed The bed (also called the river bed) is the bottom of the river (or other body of water).

brackish Beackish water is water that is saltier than river water but less salty than sea water. channel A channel is an area that contains flowing water confined by banks. A stream is flow of water, driven by gravity, in a natural channel, on land.

A small brook in a meadow and the Amazon River are both streams. It is interesting to watch water on a recently bulldozed construction site with a slope.

At first the water saturates the ground and begins to flow downhill across the surface of the slope in a thin sheet.

[Geoffrey E Petts; Peter Calow;] -- Many of the problems for river management today relate to landuse changes, water resource development and industrial expansion which have altered the pattern of run-off, the quality of river water.

In an era of river repair, recovery enhancement approaches have been used to guide river conservation and rehabilitation in some parts of the world for a decade or more. 14, 18, 25,31,[54][55][   Scientists and engineers design river topography for a wide variety of uses, such as experimentation, site remediation, dam mitigation, flood management, and river restoration.

A recent advancement has been the notion of topographical design to yield specific fluvial mechanisms in conjunction with natural or environmental flow releases. For example, the flow Cited by: means that gradient, or slope, of the surface over which the river flow plays an important role in conditioning the velocity of the river.

Channel Shape. The shape of the channel affects the velocity of a river. Around the perimeter of the river -- that is, at the sides and along the river bed -- friction is created as water flows against the edges.What water flow conditions might cause a deep, narrow river channel to form in a stream table?

A rapid and frequent variation in discharging water is also required. A river with banks that are resistant to erosion could form meandering deep and narrow channels, while a river with banks that are erodible will form shallow, wide channels sustaining helical flows that result in the formation of braided channels.
