This report includes several photographs and illustrations, as well as text, to describe a portable unit for filtering water samples. It "is preliminary and has not been edited or reviewed for conformity with Geological Survey standards and nomenclature."

Abstract: "Results of an investigation conducted to determine the engineering feasibility of using dredged material to expand an existing marshland area are presented. Dredged material obtained from maintenance dredging operations was found suitable for use as marsh substrate and site conditions were found adequate for construction of a containment facility. Factors evaluated in the study include site-specific feasibility of marsh expansion using dredged material, sizing of the demonstration area to meet water-quality and storage needs, preliminary design of the containment facility, procedures for the placement of dredged material, and identification of alternative construction methods, materials, and costs. Overall feasibility of marsh expansion was demonstrated and additional investigations were recommended for the project."

This report examines and describes the geohydrologic status of the Albin and La Grange areas, specifically focusing on the use of irrigation wells to access ground water. Includes maps and illustrations.

Abstract: This report presents flood magnitude and frequency relations applicable to 'unregulated streams in Kentucky. The relations are based on flood data at 117 gaging stations in Kentucky and 14 in adjacent states having 10 or more years of record not significantly affected by man-made changes . Equations that relate flood magnitude and frequency to contributing drainage area in 16 geographic areas may be used to estimate magnitude of future floods with recurrence intervals of as much as 100 years on gaged and ungaged streams having drainage areas of 10 to 4,300 square miles (25 .9, to 11,100 square kilometers) . Estimating equations are also presented in graphical form for the convenience of the user . Additional graphs are presented to estimate flood magnitude for selected recurrence intervals along the Cumberland, Kentucky, and Ohio Rivers .

Report and Geographic Survey. Report reveals "relations for estimating peak flows and mean annual flow for natural streams in Wyoming using the channel-geometry method and basin-characteristics method. Also includes maps, graphs, and photographs.

Abstract: A time of travel study of a 106-mile (171-kilometer) reach of the Sandusky River and a 39-mile (63-kilometer) reach of Tymochtee Creek was made to determine the time required for water released from Killdeer Reservoir on Tymochtee Creek to reach selected downstream points. In general, two dye sample runs were made through each subreach to define the time-discharge relation for approximating travel times at selected discharges within the measured range, and time-discharge graphs are presented for 38 subreaches. Graphs of dye dispersion and variation in relation to time are given for three selected sampling sites. For estimating travel time and velocities between points in the study reach, tables for selected flow durations are given. Duration curves of daily discharge for four index stations are presented to indicate the low-flow characteristics and for use in shaping downward extensions of the time-discharge curves.
