Flow Routing in the Susquehanna River Basin: Part II - Low-Flow Frequency Characteristics of the Susquehanna River Between Waverly, New York and Sunbury, Pennsylvania

From introduction: The primary objective of this study, second in the series, is the development, calibration, and verification of flow-routing models for the Susquehanna River from Waverly, New York, to Sunbury, Pennsylvania. These models will permit SRBC to estimate the effects of water-resource developments upstream from Waverly at six locations on the Susquehanna River. They were also used to simulate for existing conditions at two ungaged sites.

Sources of Limestone, Gypsum, and Anhydrite for Dusting Coal Mines to Prevent Explosions

From Preface: "The writer began testing the rock-dusting method for the Bureau of Mines at the Pittsburgh gallery in 1909, and later continued such testing in the bureau's experimental mine, with favorable results. Beginning in 1911 the bureau issued reports recommending rock dusting as alternative to watering."

Handling Barnyard Manure in Eastern Pennsylvania (open access)

Handling Barnyard Manure in Eastern Pennsylvania

"Barnyard manure is handled with special care and excellent results by farmers in certain parts of Eastern Pennsylvania. For over a century it has been the custom in this region to store stable manure in a walled manure yard, partly or wholly covered, in which the stabled animals are allowed to exercise during the day. Manure thrown into such a yard and thoroughly tramped by stock loses much less through heating and leaching than does manure piled in the open. This bulletin describes the manure-yard method of handling manure and outlines the farm practices of ten successful farmers who follow this method." -- p. 2

Selected Water Resources Data, Clarion River and Redbank Creek Basins, Northwestern Pennsylvania--Part 2

Abstract: This report presents selected basic data collected during a study of the water resources of the Clarion River and Redbank Creek basins in northwestern Pennsylvania. Hydrologic information including data on aquifers, water levels, and yields is presented for 1,304 wells. Records for 51 springs are also given. The report contains 83 chemical analyses of water samples collected from 30 stream sites and 300 analyses of water from 196 wells and 43 springs. Also included are 103 trace-elements analyses. Monthly and annual means of ground-water levels for six observation wells are tabulated. Benthic invertebrate data from 136 stream sites are listed. Locations of data-collection sites are shown on 50 page-size reductions of 7.5-minute topographic quadrangle maps.

Structure and Propagation of Turbulent Bunsen Flames

From Introduction and Summary: "In the assessments of research objectives after World War II it was brought out that little effort had yet been expended on an understanding of turbulent flames.The present report deals exclusively with a second stage of work which was carried out between November 1954 and August 1959. This summary report includes a few new data, but its chief purpose is to reorient the findings toward a better appreciation of what has been accomplished and what most profitably might be done in the near future."
