Paleohydrologic phenomena recorded by lake sediments
Thomas C. Winter, H.E. Wright Jr.
1977, Earth and Space Science (58) 188-196
Hydrologic phenomena are dynamic, so their understanding and prediction are difficult and challenging. Many are cyclic, ranging from diurnal, seasonal, and annual cycles to climatic fluctuations of many hundreds or thousands of years. Predicting the magnitude and recurrence intervals of long-term fluctuations of these phenomena is a primary...

1977, Groundwater (15) 276-283
The recent interest in the disposal of treated sewage effluent by deep-well injection into salt-water-filled aquifers has increased the need for proper disposal of salt water as more wells are drilled and tested each year.The effects on an unconfined aquifer of the improper disposal of salt water associated with the...
Storage of treated sewage effluent and stormwater in a saline aquifer, Pinellas Peninsula, Florida
J.S. Rosenshein, J.J. Hickey
1977, Groundwater (15) 284-293
The Pinellas Peninsula, an area of 750 square kilometres (290 square miles) in coastal west-central Florida, is a small hydrogeologic replica of Florida. Most of the Peninsula's water supply is imported from well fields as much as 65 kilometres (40 miles) inland. Stresses on the hydrologic environment of the Peninsula...
Post-breeding activities of mallards and wood ducks in north-central Minnesota
D.S. Gilmer, R.E. Kirby, I.J. Ball, J. H. Riechmann
1977, Journal of Wildlife Management (41) 345-359
We used radio telemetry to monitor the post-breeding activities of 129 mallards (Anas platyrhynchos) and 118 wood ducks (Aix sponsa) on a 932-km2 area in north-central Minnesota from 1968 to 1974. Upon completion of breeding activities and before the flightless period, all mallard drakes departed the area; this exodus peaked...

Routing of stormwater flows through storm drains
Marshall E. Jennings, Thomas N. Keefer
1977, Journal of Research of the U.S. Geological Survey (5) 301-305
Storm-drain flow-routing methods based on kinematic-wave routing and storage-routing methods are compared with the MLSR (multiple-linearization storm-drain routing) method for hypothetical circular pipe problems. The MLSR method, based on a diffusion-wave routing concept, is shown to give very good results without incurring the numerical solution or damping problems of...
Virion RNA polymerases of two salmonid rhabdoviruses
P. E. McAllister, R.R. Wagner
1977, Journal of Virology (22) 839-843
RNA-dependent RNA polymerases were found to be associated with two salmonid rhabdoviruses: infectious hematopoietic necrosis (IHN) virus and the virus of hemorrhagic septicemia (VHS). The protein composition of these rhabdoviruses closely resembles that of rabies virus rather than that of vesicular stomatitis virus (McAllister and Wagner, 1975). The optimal temperature...
