Short-term response of a mountain stream to a sediment pulse and a major flood
Sediment pulses in river systems can result in massive inputs of sediment compared to background transport rate. Large floods, on the other hand, temporarily bolster a river’s sediment transport ability. Both phenomena occurred in the Sullivan Creek watershed of northeastern Washington within the …

LiDAR Assessment of Sediment Transport Related to the Removal of the Marmot Dam, Sandy River, Oregon
… 1) to investigate how the dam removal affected sediment distribution in the lower reach of the river, several km downstream of the dam, 2) to determine whether the pulse of sediment from the dam removal created a detectable, successive downstream accumulation of sediment through time, and 3) to …

Temporal and Spatial Variation of Fine Sediment Infiltration in a Gravel-Bed River
Pulses of fine sediment in gravel-bedded rivers can cause extensive fine sediment infiltration (FSI), potentially altering river morphodynamics and aquatic ecosystems. FSI occurs when sand and silt are deposited into void spaces between larger grains at the riverbed. Flume and theoretical modeling …

Quantifying Channel Responses to the Removal of the Glines Canyon Dam in the Middle Reach of the Elwha River, Washington
… accumulate the new influx of woody debris and sediment from the dam removal, which influenced the response of the river channel. The change that occurred was quantified by using repeat Terrestrial LiDAR (TLS), sediment distribution surveys, and large woody debris mapping techniques. The …

Lateral response of alluvial rivers to the downstream passage of episodic sediment pulses
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-12-01

Numerical Simulation of the Propagation of Fine-Grained Sediment Pulses in Alluvial Rivers
Sediment pulses are defined as large amounts of loose sediment that are suddenly deposited in river corridors due to the action of external factors or processes of natural or anthropogenic origin. Such factors and processes include landslides, debris flows from tributaries, volcanic eruptions, dam …

Advanced Suspended Sediment Sampling and Simulation of Sediment Pulses to Better Predict Fluvial Geomorphic Change in River Networks
Sediment, an integral part of rivers and watersheds, is eroded from, stored in, and transported through various watershed components. Rivers often receive sediment in the form of episodic, discrete pulses from a variety of natural and anthropogenic processes, this sediment can be transported …
