Measurement and Prediction of Sediment Yields in Wisconsin Streams

Description: From introduction: This report presents practical and useful sediment-yield information for Wisconsin. Measured and estimated sediment yields are supplemented by information on suspended-sediment concentration and particle size of suspended and bed material for 84 sites in the State. To expand the usefulness of these data, an additional section in the report presents a method to estimate or predict sediment yields in ungaged streams.

Hydrologic Considerations Associated with Dredging Spring Ponds in Wisconsin

Description: From purpose and scope: This report describes the hydrology of selected spring ponds and the effect that dredging has had on the ponds and their surrounding areas. The report emphasizes the water budgets for the ponds, discusses the hydrologic system which contains the ponds, and briefly describes water quality in the study area.

Low-Flow Characteristics at Gaging Stations on the Wisconsin, Fox, and Wolf Rivers, Wisconsin

Description: From introduction: The purpose of the low-flow characteristics are in some instances affected by the period of record. These characteristics can vary as much as +/- 30 percent at some gaging stations depending on whether or not the severe drought of the 1930's was included in the analysis.

Recovery of Zinc from Low-Grade and Complex Ores

Description: From Introduction: "Vocalization in retorts has been, until recently, the only commercial process of producing spelter, hence the zinc mine operators have had to meet the terms of the zinc mine operators have had to meet the terms of the zinc smelters in regard to the following requirements: (1) Minimum percentage of zinc the ore must contain; (2) the chemical combination of the zinc in the ore; (3) the proportion present of those elements that interfere with the successful recovery of the zinc when the ore is retorted. As stated previously, and as will be shown later, a large part of the valuable mineral content of the ore is lost in effecting this concentration. As a result of the other requirements that have to be met in zinc smelting, much zinc is lost in the mining and milling of zinc ore."

Vacuum-Freezing Vapor-Compression Process: Evaluation on Brackish Water

Description: From Abstract: "The Vacuum-Freezing Vapor-Compression (VFVC) Process was evaluated on high salinity brackish water during the period from February 1968 through December 1969 by Colt Industries Inc., under O.S.W. Contract No. 14-01-0001-967 at Roswell, New Mexico. The 15,000 gpd VFVC test plant is mounted on a mobile trailer which was built by Colt Industries Inc. in their factory at Beloit, Wisconsin. Prior to operation at Roswell, the plant was operated at Wrightsville Beach, North Carolina to check out the system and to operate the trailer on sea water." Process Description: "A simplified diagram, Figure 2, shows both the essential components of the process and flow paths of the various streams in the system. Typical heat and mass balances are shown on Figures 3 and 4."

City Smoke Ordinances and Smoke Abatement

Description: From Introduction: "In connection with the fuel investigations conducted by the Bureau of Mines much information has been accumulated as to the smoke abatement activities in various cities. The essential features of the information are presented in this report, which, it is believed, will be of public interest and benefit, especially to those communities that are just beginning organized effort to abate unnecessary smoke."

Coal-Mine Accidents in the United States and Foreign Countries

Description: From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."
