The effects of boundary conditions on the steady-state response of three hypothetical ground-water systems; results and implications of numerical experiments
O. Lehn Franke, Thomas E. Reilly
1987, Water Supply Paper 2315
The most critical and difficult aspect of defining a groundwater system or problem for conceptual analysis or numerical simulation is the selection of boundary conditions . This report demonstrates the effects of different boundary conditions on the steady-state response of otherwise similar ground-water systems to a pumping stress. Three series...

1987, Open-File Report 87-509
Geochemical data for samples from 55 postorogenic plutons of the southwestern Arabian Shield show that these granitoids are generally less evolved than similar granitoids of the eastern Arabian Shield. Radioelement contents are low to normal relative to typical granitic rocks and uranium contents are distinctly low relative to rocks of...
