A model for simulation of flow in singular and interconnected channels
Raymond W. Schaffranek, R.A. Baltzer, D.E. Goldberg
1981, Techniques of Water-Resources Investigations 07-C3
A one-dimensional numerical model is presented for simulating the unsteady flow in singular riverine or estuarine reaches and in networks of reaches composed of interconnected channels. The model is both general and flexible in that it can be used to simulate a wide range of flow conditions for various channel...

Annotated bibliography of remote sensing methods for monitoring desertification
A. S. Walker, Charles J. Robinove
1981, Circular 851
Remote sensing techniques are valuable for locating, assessing, and monitoring desertification. Remotely sensed data provide a permanent record of the condition of the land in a format that allows changes in land features and condition to be measured. The annotated bibliography of 118 items discusses remote sensing methods that may...

1981, Water Supply Paper 2068
Data obtained during a hydrologic reconnaissance in 1975-77 in the Wasatch Plateau-Book Cliffs coal-fields area of Utah were correlated with existing long-term data. Maps were prepared showing average precipitation, average streamflow, stream temperature, ground- and surface-water quality, sediment yield, and geology. Recommendations were made for additional study and suggested approaches...
