Going By the Flow Using Acoustics To Track Stream Sediment
suspended-sediment load sampling will become available after about 3 to 5 more years of experimentation and field testing. By Luis Pons, Agricultural Research Service Information Staff. This research is part of Water Quality and Management, an ARS National Program (#201) described on the World Wide Web

A Rare-Earth Approach to Tracing Soil Erosion
in the sampling shed and is later analyzed for rare-earth tracers. (D117-1). A New Extraction Method, Too. Zhang and Nearing have developed and tested a quick, acid-leaching method for extracting for analysis these oxides from soil and sediment samples. The technique employs inductively coupled plasma-mass

Environmental Particle Analysis
of sediments it may well give important information about the origin and distribution of material through the action of tidal, wind and other flows. Often the examination of the size of pollen granules present in the sediment can provide important information about a site (such as what types of plant life were

Clean Waters and Agriculture
in the Water. On technology's cutting edge, NSL scientists are using automated and acoustic sampling to assess sediment's impact on waterways and dams and then using computer modeling to analyze this data and make predictions. Hydraulic engineers Roger Kuhnle and Daniel Wren, with collaborators

Oil Analysis-Proper Testing for Maximum Value and Equipment Condition Information
, AFTER enough oil has flowed to allow for purging sediment. around the plug hole or static oil has been removed from the piping. Two additional items in the utilization of a program are: 4. Proper paperwork and. 5. Prompt delivery of the samples to the laboratory. The adage "the job's not over until

Precise Inputs for a Cleaner Environment
the drains in the fall, winter, and spring is greatly reduced. Recently, the Ohio researchers began testing the treating, storing, and reusing of drainage and surface runoff water to irrigate. The water is routed to a wetland constructed for that purpose. The wetland removes sediment and nutrients

Working With Nature To Keep the Chesapeake Healthy
flooding and sediment movement. But just which types and sizes are most effective? Much of the previous research on this subject has focused on just one or two aspects of a riparian ecosystem. But McCarty's work looks at a riparian system as a whole to see how different processes interact and affect
