Bridge scour countermeasure assessments at select bridges in the United States, 2016–18
In 2009, the Federal Highway Administration published Hydraulic Engineering Circular No. 23 (HEC-23) to provide specific design and implementation guidelines for bridge scour and stream instability countermeasures. However, the effectiveness of countermeasures implemented over the past decade following those guidelines has not been evaluated....Dudunake, Taylor J.; Huizinga, Richard J.; Fosness, Ryan L.
Sediment transport monitoring of the Yankee Fork of the Salmon River near Stanley, Idaho, 2012–15
The Yankee Fork of the Salmon River is one of the larger watersheds in the upper Salmon River subbasin of central Idaho. Mining activities since the late 19th century, specifically placer mining and associated dredging from 1940 to 1953, have left the fluvial system in a highly altered and unnatural state. To improve aquatic and terrestrial...Johnsen, James W.
Understanding the captivity effect on invertebrate communities transplanted into an experimental stream laboratory
Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this knowledge gap, we conducted a 32‐d test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival...Schmidt, Travis S.; Rogers, Holly; Miller, Janet L.; Mebane, Christopher A.; Balistrieri, Laurie S.
