Michael J. Mallory
1979, Water-Resources Investigations Report 79-18
This report documents a finite-element model for simulation of ground-water flow in a two-aquifer system where the two aquifers are coupled by a leakage term that represents flow through a confining layer separating the two aquifers. The model was developed by Timothy J. Durbin (U.S. Geological Survey) for use in...
Quantity and quality of urban runoff from three localities in the Denver Metropolitan area, Colorado
Sherman R. Ellis, William M. Alley
1979, Water-Resources Investigations Report 79-64
Considerable variation in constituent concentrations was shown in urban runoff data for 1975-77 from three metropolitan Denver drainage basins. Constituent concentrations, greatest during initial rainfall runoff, generally peaked midday of snowmelt runoff, corresponding with maximum melting and runoff. Instantaneous loads of constituents were largely a function of discharge. Days since...
