Stream simulation in an analog model of the ground-water system on Long Island, New York
Arlen W. Harbaugh, Rufus T. Getzen
1977, Water-Resources Investigations Report 77-58
The stream circuits of an electric analog model of the ground-water system of Long Island were modified to more accurately represent the relationahip between streamflow and ground-water levels. Assumptions for use of the revised circuits are (1) that streams are strictly gaining, and (2) that ground-water seepage into the streams...

Computation of records of streamflow at control structures
Dannie L. Collins
1977, Water-Resources Investigations Report 77-8
Traditional methods of computing streamflow records on large, low-gradient streams require a continuous record of water-surface slope over a natural channel reach. This slope must be of sufficient magnitude to be accuratly measured with available stage measuring devices. On highly regulated streams, this slope approaches zero during periods of low...
Ground-water resources of the Riviera Beach area, Palm Beach County, Florida
L. F. Land
1977, Water-Resources Investigations Report 77-47
The principal source of freshwater that has been developed in the Riviera Beach area is the so-called shallow aquifer, which is composed of sand, shells, sandstone, limestone, marl, and occasionally clay strata. Often a stratum contains mixtures of two or more of these materials and occasionally they are cemented. The...
