The topics include changes in submarine channel morphology and slope sedimentation patterns from repeat multi-beam surveys in the Fraser River delta in western Canada, geology metrics for predicting shoreline change using seabed and sub-bottom observations from the surf zone and near-shore, seabed disturbance and bedform distribution and mobility on the storm-dominated Sable Island Bank of the Scotian Shelf, analyzing bedforms mapped using multi-beam sonar to determine regional bedload sediment transport patterns in the San Francisco Bay coastal system, and seasonal and spatial variation in suspended sediment characteristics off the Changjuang estuary.
These functions include modifying stream temperature and controlling light quantity and quality, enhancing habitat diversity, modifying channel morphology, and enhancing food webs and species richness (as shown on this magazine's cover).
Differences in CWD frequency and size between the two reaches have important consequences for observed variations in channel morphology and sediment storage.
1998), little is known about the effects of CWD on channel morphology and sediment storage in the region.
In order to evaluate the effects of CWD on channel morphology, bankfull channel dimensions were measured at 20 m intervals and 1 m upstream from all CWD obstructions.
The frequency of CWD has implications for channel morphology and sediment storage along the study reaches.
CONCLUSION--Results from this study indicate that early 20th-century logging in the Great Smoky Mountains has current implications for CWD loading and channel morphology along some streams.
Log jams formed by debris slides store extremely large volumes of sediment, the future release of which is likely to affect channel morphology in downstream reaches and may increase basin sediment yield.
This sediment loading has impacted channel morphology and stream flora and fauna," Bowes added.
Thus the excavation of channels to protect urban development changes channel morphology.
Recovery of aquatic populations in modified channels often depends upon adjustments or alterations of the channel morphology, he notes, and he also discusses how geomorphology is used to develop alternative designs and strategies to minimize the impact on natural resources.
