Digital Model of Predevelopment Flow in the Tertiary Limestone (Floridian) Aquifer System in West-Central Florida
From introduction: This study is part of a regional study of the Tertiary limestone aquifer system in the southeastern United States. The regional study encompasses all of Florida and extends into Georgia, Alabama, and South Carolina--a total area of about 82,000 square miles.

Digital-Simulation and Projection of Head Changes in the Potomac-Raritan-Magothy Aquifer System, Coastal Plain, New Jersey
From abstract: A digital model was used to simulate the response of the Potomac-Raritan-Magothy aquifer system to pumping stresses during the 18-year period, 1956-73. The model was used to compute projected potentiometric heads and trends to the year 2000. Three sets of conditions were simulated: (1) no increase in ground-water extractions, (2) continued growth in ground-water extractions at the rate of 3 percent annually, and (3) continued growth in ground-water extractions at the rate of 3 percent annually, in conjunction with the activation of a freshwater head barrier in the fresh-salty water transition zone.

Distribution and Origin of Phosphate in the Land-Pebble Phosphate District of Florida
From abstract: The land-pebble phosphate district of Florida is a part of the Gulf Coastal Plain. The geologic formations cropping out in the district are the Miocene Hawthorn, Pliocene Bone Valley, and Pleistocene terrace sands. The Bone Valley formation consists of a lower strongly phosphatic unit and an upper less phosphatic unit. This paper is concerned principally with the lower unit, which contains the bulk of the minable phosphate deposits of the district.

A Dithizone Method for the Determination of Lead in Monazite
The following report discusses a method for determining lead in monazite to be used as a basis for geologic age measurements. In order to develop the method it was necessary to eliminate interferences due to the presence of phosphates of thorium and the rare-earth metals.

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.
