1982, Water-Resources Investigations Report 82-4104
Fluvial-sediment data were collected for the San Juan River near Bluff beginning in 1914 and terminating in 1980. A double-mass curve showed a change in relationship between annual suspended-sediment discharge and annual stream discharge between the water years 1941-44 and 73. Possible causes for these changes in laboratory procedures, and...

Quadratic spline subroutine package
Lowell A. Rasmussen
1982, Water-Resources Investigations Report 82-41
A continuous piecewise quadratic function with continuous first derivative is devised for approximating a single-valued, but unknown, function represented by a set of discrete points. The quadratic is proposed as a treatment intermediate between using the angular (but reliable, easily constructed and manipulated) piecewise linear function and using the smoother...

David A. Stedfast
1982, Water-Resources Investigations Report 81-55
A one-dimensional transient-flow-simulation model was developed to represent a 76-mile reach of the tidal Hudson River between Albany and New Hamburg. In this reach, the direction of flow reverses four times daily as a result of tidal influence; this produces complex current patterns and retards the rate at which the...

L.J. Torak
1982, Water-Resources Investigations Report 82-4025
This report describes modifications incorporated into the finite-difference model for simulation of groundwater flow in three dimensions. These modifications extend the application of this model to simulations involving head-dependent sources and sinks (i.e., rivers, evapotranspiration, and springs or drains). Other modifications are made that enhance the iterative-solution process of the...

Richard J. Reynolds
1982, Water-Resources Investigations Report 81-48
On Long Island, base flow under nonurbanized conditions constitutes 90 to 95% of total stream discharge. Base-flow data from 19 continuously gaged streams are presented as monthly mean and annual mean discharge for water years 1960-75, which includes the 1962-66 drought.

Method for relating suspended-chemical concentrations to suspended-sediment particle-size classes in storm-water runoff
Joseph F. Rinella, Stuart W. McKenzie
1982, Water-Resources Investigations Report 82-39
A method has been developed to relate suspended-chemical concentrations (associated with suspended sediments) in storm-water runoff to suspended-sediment particle-size classes. These classes are based on settling velocities in quiescent native water. This method requires processing 20 liters of water having a suspended-sediment concentration greater than 500 milligrams per liter. However,...
