Available in PDF, EPUB and Kindle. Book excerpt: Of the nearly 11,500 bridges in Wisconsin, 89 have been assessed with critical scour conditions. The U.S. Geological Survey, in cooperation with the Wisconsin Department of Transportation, the Marathon County Highway Department, and the Jefferson County Highway Department, performed routine monitoring of streambed elevations for three bridges. Two monitoring approaches were employed: (1) manual monitoring using moderately simple equipment, and (2) automated monitoring, using moderately sophisticated electronic equipment. The results from all three sites demonstrate that both techniques can produce reasonable measurements of streambed elevation. The manual technique has a lower annual operating cost, and is useful for cases where documentation of long-term trends is desired. The automated technique has a higher annual operating cost and is useful for real-time monitoring of episodic events with short time durations.

This book was released on 2003 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water-quality data are provided for six sites in Navajo National Monument in northeastern Arizona. These data describe the current water quality and provide baseline water-quality information for monitoring future trends. Water samples were collected from six sites near three ancient Indian ruins during September 2001 to August 2002. Two springs and one well are near Betatakin Ruin, one spring is near Keet Seel Ruin, and one spring and one stream are near Inscription House Ruin. Water from all the sites is from the N aquifer, a regional sandstone aquifer that is the source of drinking water for most members of the Navajo Nation and Hopi Tribe in northeastern Arizona. Concentrations of dissolved solids, major ions, trace elements, and uranium were low at the six sites. Dissolved-solids concentration ranged from 94 to 221 milligrams per liter. Concentrations of dissolved nitrate (as nitrogen) were generally low (less than 0.05 to 0.92 milligrams per liter) and were within the range of concentrations at other N-aquifer sites within 20 miles of the study area. Water samples from Inscription House Spring, Navajo Creek Tributary (near Inscription House Ruin), and Keet Seel Ruin Spring contained indicators of human or animal wastes-fecal coliform and Escherichia coli bacteria.

This book was released on 2000 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The N aquifer is the major source of water in the 5,400-square-mile area of Black Mesa in northeastern Arizona. Availability of water is an important issue in this area because of continued industrial and municipal use, a growing population, and a precipitation of only about 6 to 12 inches per year. The monitoring program in Black Mesa has been operating since 1971 and is designed to determine the long-term effects of ground-water withdrawals from the N aquifer for industrial and municipal uses. The monitoring program includes measurements of (1) ground-water pumping, (2) ground-water levels, (3) spring discharge, (4) surface-water discharge, and (5) ground-water chemistry. In 1999, total ground-water withdrawals were 7,110 acre-feet, industrial use was 4,210 acre-feet, and municipal use was 2,900 acre-feet. From 1998 to 1999, total withdrawals increased by 0.7 percent, industrial use increased by 4 percent, and municipal use decreased by 4 percent. From 1998 to 1999, water levels declined in 11 of 15 wells in the unconfined part of the aquifer, and the median decline was 0.7 foot. Water levels declined in 14 of 16 wells in the confined part of the aquifer, and the median decline was 1.2 feet. From the prestress period (prior to 1965) to 1999, the median water-level decline in 31 wells was 10.6 feet. Median water-level changes were 0.0 foot for 15 wells in the unconfined part of the aquifer and -45.5 feet in 16 wells in the confined part. From 1998 to 1999, discharges were measured annually at four springs.
