The aim of this study was to provide baseline data on floodplain forest structure, composition, and function that would be needed to predict and monitor the consequences of a proposed stream restoration project. This project would involve
the dechannelization of Stokes Creek, a stream in western Tennessee that was channelized and leveed in the first half of the 1900s.

perennial streams in the transition zone of central Arizona. Canonical correspondance analysis (CCA) with a forward selection was used to assess quantitatively the role of stream power in riparian vegetation patterns.

In volcanic areas of Idaho, Oregon and Montana, a number of perennial stream emerge from single springs or zones of springs. The AA. investigate the geomorphic setting, planform, and topography of the spring-dominated channels; the size and nature
of spring-dominated streams was reflected in the fluvial geomorphology of these streams.

The systematic changes in iron geochemistry often experienced by sediments deposited in an anaerobic environment, such as stream channel or waterlogged floodplain, are used here as an indicator of residence time over contemporary time scales

in channel beds. There are indications that in-stream wetlands will continue to expand and trap sediment. The volume of fine-grained sediment increases with wetland age. The in-stream wetlands may provide a significant capacity to buffer erosion from gullied

of grain size and slope on channel width and the effect of width and grain size on channel slope. The regime equations are successful even though they were devised for single channel gravel streams. The results confirm the influence of grain size on channel
pattern thresholds and demonstrates, using spatial transitions in channel pattern, that channel pattern predictions based on stream power alone are inadequate.
Gully initiation and road-to-stream linkage in a forested catchment, southeastern Australia
This study reports the nature of sediment delivery pathways and road-to-stream linkage in a forested catchment in southeastern Australia, and evaluates the causal factors associated with this linkage. Results are discussed within the context of road
Impact of wastewater discharge on the channel morphology of ephemeral streams

The impact of wastewater flow on the channel bed morphology was evaluated in 4 ephemeral streams in Israel and the Palestinian Territories : Nahal Og, Nahal Kidron, Nahal Qeult and Nahal Hebron. Channel changes before, during and after the halting
A large and geographically diverse data set consisting of meandering, braiding, incising, and post-incision equilibrium streams was used in conjunction with logistic regression analysis to develop a probabilistic approach to predicting thresholds
of channel pattern and instability. An energy-based index was developed for estimating the risk of channel instability associated with specific stream power relative to sedimentary characteristics. The logistic regression approach developed in this study

This paper examines rates of bed load movement through stream channels by relating annual travel distance to simple basin or channel characteristics such as reach-averaged basal shear stress, drainage area or bankfull channel width. The intent
for planning restoration of stream habitats in the western USA and other regions with similar channel characteristics and sediment supply.

The aim of this study was to infer process rates from profile form using best-fit criteria, to use these rates to estimate the ages of the profiles, and then to compare these ages with ages derived from stream-incision rates. Therefore field surveys
. Holocene activity was likely limited to reworking of thick dune crests. Four sites representing these dunes have been selected for study. Two are along streams that have headwaters in the Piedmont, and two are along streams entirely within the Coastal Plain.
