Time-of-travel study in the Sebasticook River basin, Maine
Gene W. Parker
1981, Open-File Report 81-545
Time of travel was determined for four reaches of the Sebasticook River, two on the East Branch Sebasticook River, and two on the main stem of the Sebasticook River. Reach A included 7.8 miles of the East Branch Sebasticook River from Dexter to Corinna, Maine. Reach B included 8 miles...

One-dimensional reservoir-lake temperature and dissolved oxygen model
Leo B. House
1981, Water-Resources Investigations Report 82-5
This report describes and documents a one-dimensional computer model that predicts dissolved-oxygen and temperature profiles in a lake or reservoir. Downstream release dissolved-oxygen concentrations and temperatures also are computed based on a user-specified outflow withdrawal elevation. The model can, therefore, be used to compare top-draw versus bottom-draw outlet configuration effects...
Comparison of the propane-area tracer method and predictive equations for determination of stream-reaeration coefficients on two small streams in Wisconsin
Leo B. House, Steven Skavroneck
1981, Water-Resources Investigations Report 80-105
This study was made to identify the best predictive equations for a stream's reaeration-rate coefficient. Reaeration-rate information is needed in dissolvedoxygen modeling work, but an actual tracer measurement is not always possible. The propane-area gas-tracer method and predictive equations were compared for determination of stream-reaeration coefficients (K.2) for reaches of two...

Research in the Geysers-Clear Lake geothermal area, Northern California
Robert J. McLaughlin, Julie M. Donnelly-Nolan, editor(s)
1981, Professional Paper 1141
The Geysers-Clear Lake area is one of two places in the world where major vapor-dominated hydrothermal reservoirs are commercially exploited for electric power production. Because energy can be extracted more efficiently from steam than from hot water, vapor-dominated systems are preferable for electric power generation, although most geothermal electric power...
