The thick sandstone units of the Nagri Formation from eastern Potwar are interpreted as deposits of sinuous, braided channel and the stacking pattern is believed to represent the movement of channels within single or multiple channel belts, whereas individual storeys are thought to be channel-bar deposits of a single flood (Khan et al.
The internal setting of the bars probably suggests deposition by rivers with a moderate to high flow rate in 10-15 meters deep braided channels with a dominant paleoflow direction to the SSW, which is fairly similar to the present day Indus River system (Abbasi, 1994, 1998).
The river had a wide flood plain and a braided channel, especially in the Heber valley and Utah valley areas.
Stream surveys and watershed assessments conducted over the years by various agencies have noted a number of problems: unstable stream banks contributing sediment to the creek, a lack of instream structure and habitat complexity, a lack of large conifers in the riparian zone to provide large woody debris (an important component of fish habitat), and severely aggraded conditions (the deposit of sediment) in the lower portion of the creek, resulting in a braided channel and subsurface flow in the late summer and early fall.
Before the Willamette River was dammed, Sonnichsen said, "The river flowed right here where we stand - it was a broad river of many braided channels.
It was he who pointed out that the scablands' undulating surfaces and incised, braided channels mirrored those that could be seen in streambeds everywhere.
Historically, the Missouri River consisted of braided channels that moved from year to year across a wide flood plain.
The new ponds will be linked by a cascading stream with a variety of river features, such as riffles and braided channels, which it is hoped will enable the wetlands to support an increased range of plant and animal species, including dragonflies, damselflies, amphibians, little grebe, kingfisher and grey wagtail.
Channel instability is a particularly common problem in western North America, where streams that were formerly stable, narrow meandering channels, have been converted into wide, shallow, braided channels in response to destabilizing influences such as ill-advised channel works or land use changes upstream, as illustrated on the Blanco River, Colorado (NRC 1992).
The work being done this week, followed by the planting of native vegetation later this fall, will restore a system of braided channels and sloughs that have been walled off from the river since the first half of the 1900s.
Many streams were perennial with wide, braided channels and abundant bankside vegetation.
