Cyclic landsliding at Wrightwood, southern California: A preliminary report
Douglas M. Morton, Russell H. Campbell
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.

1978, Open-File Report 78-95
A Tsunami Microprocessor Tide System was developed to replace the Advanced Tsunami Tide System. The use of microprocessor based systems will reduce manpower and hardware costs from $4,000 per advanced system to $400 per microprocessor system. In addition to the cost reduction; the capacity, capability, and flexibility of the microprocessor...

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...
Evaluation and design of a streamflow-data network in Washington
Marshall E. Moss, W.L. Haushild
1978, Open-File Report 78-167
A method of evaluating the transferability of streamflow information by regional regression analysis was applied in Washington to several streamflow variables. The annual mean and annual standard deviation were chosen to represent the development potential of the water resource, while the mean, standard deviation, and the 50-year recurrence interval of...

1978, Open-File Report 78-559
More than 1400 m of fine-grained clastic rocks and reefoid limestones constitute the lower part of an Upper Devonian transgressive-regressive cycle in the central Brooks Range, Alaska (Dutro and others, 1977). The Hunt Fork Shale and an underlying heterogeneous unit (unnamed) were measured and sampled on the east side of...
Historical profile, Quality of Water Laboratories, U. S. Geological Survey
W. H. Durum
1978, Open-File Report 78-432
During the period 1918 to 1973 the U.S. Geological Survey, Water Resources Division, established 22 District-type water quality laboratories. These facilities provided the analytical capability and water-quality information for hydrologic investigations and the national baseline inventory of chemical, physical, fluvial sediment, and biological characteristics of surface and ground waters in...

1978, Open-File Report 78-473
Analyses of the surface effects of past underground coal mining in the western Powder River Basin suggest that underground mining of strippable coal deposits will damage the environment more over long periods of time than will modern surface mining, provided proper restoration procedures are followed after surface mining. Subsidence depressions...
