What�ll They Think of Next? Dewatering Contaminated Slurries Using Geotextile Tubes
Sediment must be dredged from the bottom of waterbodies to maintain their capacity and navigability. Dredging, by its nature, involves the removal of highwater-content slurries and also helps preserve...
Sediment Pollution: Solving "Rill" Problems Using RECPs
Sediment pollution causes an estimated $16 billion in environmental damage annually. Sediment is the most common pollutant in rivers, streams, lakes, and reservoirs, causing such negative effects as temperature...
Maintenance
While site selection and proper construction are the most critical factors in establishing that permeable pavements function as designed, all must be inspected and maintained to maximize...
Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...
Viral Fate and Transport Modeling under Salinity Impact
This research studied the impact of salinity on sorption and transport of MS-2 in saturated sand through one-dimensional column experiments. MS-2 was used as a surrogate to understand...
Probabilistic Analysis of Long-Term Aquifer Recharge
Long-term time series of aquifer recharge and other aquifer fluxes (aquifer discharge, groundwater extraction) are essential to monitor and understand aquifer processes. This paper presents...
Fundamentally Sound
Through careful coordination of remediation work that will include the dredging of contaminated sediment and the control of storm water, a busy Seattle shipyard is charting a course for...
Monitored Natural Recovery and Dredging Decision Analysis at Bellingham Bay, Washington
The Whatcom Waterway Site, located within inner Bellingham Bay, Washington consists of intertidal and subtidal aquatic lands within and adjacent to the Whatcom Waterway in Bellingham,...
Sediment Remediation at the Unnamed Tributary to the Ottawa River
A sediment removal action was conducted in the Unnamed Tributary to the Ottawa River to address sediments containing polychlorinated biphenyls(PCBs) at concentrations up to 74,000 mg/kg....
Application of the NRC Framework for Evaluation of Remedial Actions at a PCB Contaminated Sediment Site
The National Research Council recently proposed that the framework of the Presidents/Congressional Commission on Risk Assessment and Risk Management be applied to the selection and implementation...
Larger Foraminifers as Contributors to Carbonate Beach Sands
Larger foraminifers are locally significant contributors to tropical carbonate sediments, particularly in the Indo-Pacific region. The two major factors influencing foraminiferal production...
Amino Acid Geochronology Applied to the Dating of Eolianites on San Salvador Island, Bahamas
Using amino acid racemization data measured on carbonate eolianite sediments, we assess the ability of amino acid geochronology to distringuish among several stratigraphic units on San...
Testing a Multi-Tiered Stress-Gradient Model for Risk Assessment Using Sediment Constituents from Coral Reef Environments
Coral reefs are threatened worldwide by stresses ranging from local to global in extent. Local stresses range from boat/ship groundings and sewage outfalls to dredging and coastal clearing....
Characteristics and Implications of Relict Carbonate Paleoshorelines
Throughout the Florida-Bahamas region, the accumulation of coastal carbonate deposits, excepting the present highstand, appears to be episodic. Back through time these deposits provide...
Turbulence, Bottom Boundary Conditions, and Sediment Transport in a Shallow Water Habitat
Field experiments were designed to explore the effects of vegetation on the hydrodynamics and sediment transport in Franks Tract, a shallow water habitat in the Sacramento-San Joaquin...
Sediment and Nutrient Monitoring and Modeling in Lake Tahoe Basin, California, U.S.A.
The water quality of Trout Creek, South Lake Tahoe, California is monitored to assess the system's response to stream restoration. It is the principal endeavor to conduct a systematic...
Buffalo Cove Water Management Unit, Atchafalaya Basin, LA: A Case Study
The Atchafalaya Basin is a system undergoing change in topography and subsequently, hydraulics and hydrology. The U.S. Army Corps of Engineers funded and constructed an initial small-scale...
Effects of Wildfire on Water Supplies: A Case Study from Denver, Colorado
Wildfires can directly impact municipal water supplies by increasing a watersheds susceptibility to erosion, and thereby potentially increasing the transport of sediment and organic matter...
Erosion from an Industrial Forest Road in the Ouachita Mountains of Southeastern Oklahoma
Erosion from 4 segments of a 2-year old forest road in a 740 ha basin was measured for each of 105 storms that occurred in a 3.5 year period. Two road segments were part of a mid-slope...
Investigation of Flood Protection from Alluvial Fan Flows and Minimizing Impacts to a Sensitive Habitat Preserve: Whitewater River Basin, Coachella Valley, California
The study describes and evaluates (1) the baseline conditions to hydrology, hydraulics, wind transport of sand, sediment transport by fluvial process, the environment, economics, and (2)...
