A recognition of and solution to sediment problems in urban areas is necessary if society is to have an acceptable living environment. Soil erosion and sediment deposition in urban areas are as much an environmental blight as badly paved and littered streets, dilapidated buildings, billboard clutter, inept land use, and air, water, and noise pollution. In addition, sediment has many direct and ind

The disposal of more than 1,400 million pounds of solid wastes in the United States each day is a major problem.

The most dramatic variations in pore water composition occurred in Holes 2 and 3 in the Gulf of Mexico. Both holes showed a strong increase in salinity with depth, evidently owing to diffusion from underlying salt bodies. However, on Challenger Knoll (Hole 2) a sharp drop in salinity was observed in the cap rock of the salt dome in which chloride fell to only 4.8 percent. The drop is attributed to

Duck Viral Enteritis (DVE) was first recognized in North America in January 1967, when an outbreak occurred in a commercial flock of white Pekin ducks in Suffolk County, Long Island, New York (Leibovitz and Hwang, 1968b).
