Temperature in streams of New Mexico for the period October 1964 to September 1969
Ralph W. Clement
1978, Water-Resources Investigations Report 78-140
Harmonic equations were developed to describe stream temperatures at 144 sites in New Mexico using periodically observed water temperatures collected from October 1964 through September 1969. The harmonic equations explained at least 80 percent of the variability at 70 of the sites. Standard errors of estimate ranged from 1.3 to...

Walter W. Hays
1978, Open-File Report 78-933
Under the Earthquake Hazard Reduction Act of 1977, the federal government is significantly increasing its effort "to reduce the risk of life and property from future earthquakes in the United States through the establishment and maintenance of an effective earthquake hazards reduction program". This prgoram is sponsored primarily by the...
Dye-dispersion study at proposed pumped-storage project on Hudson River at Cornwall, New York
Bernard Dunn, George C. Gravlee
1978, Open-File Report 78-589
Data were collected during a dye-dispersion study on a 6-mile, tide-affected reach of the Hudson River near the proposed Cornwall Pumped Storage Project on September 21-22, 1977. The results indicated that complete mixing did not occur during the first tidal cycle but was complete after two or more cycles. The...

A water-quality assessment of the Busseron Creek watershed, Sullivan, Vigo, Greene, and Clay counties, Indiana
Stephen E. Eikenberry
1978, Open-File Report 78-13
Chemical quality of surface water in the 237-square mile Busseron Creek watershed is significantly affected by drainage from coal mines and municipalities. Drainage from coal mines is primarily a problem of higher than normal dissolved-solids concentration, whereas, drainage from municipalities is generally a problem of bacteria and phytoplankton. Generally, the...
Proceedings of Conference VI: Methodology for identifying seismic gaps and soon-to-break gaps: Convened under auspicies of National Earthquake Hazards Reduction Program, 25-27 May, 1978
Bryan L. Isacks, George Plafker
1978, Open-File Report 78-943
The fifth conference in the continuing series under the Earthquake Hazard Reduction Program was held at Massachusetts Institute of Technology on May 25- 27, 1978. Its theme was "Methodology for Defining Seismic Gaps and Soon-to-Break Seismic Gaps." One of the proposed strategies for acquiring critical data on earthquake prediction is...

1978, Open-File Report 78-1079
Recurring landslide and mudflow events in the Wrightwood area of Southern California are parts of a composite cycle of landslide activity that includes three recognizable stages. The three stages are interdependent, occur in sequence, and are of different duration. Deposits of the first stage--the largest in size--are removed to positions...
