Western Arabia lies within the low-latitude desert of north Africa and the Middle East, the core being the Arabian segment of the African Shield. The core of complex basement rocks accounts for about 670,000 km2, or one-third of the Arabian Peninsula. Reconnaissance mapping of these crystalline rocks, together with bordering...
Evaluation of a watershed model to simulate sediment transport in a small agricultural watershed in Indiana
L. D. Arihood
1989, Water-Resources Investigations Report 88-4222
The streamflow and sediment components of the watershed model, ' Hydrologic Simulation Program-Fortran ', were evaluated using 2 years and 9 months of data from a 2.7-sq mi agricultural watershed in Indiana. Hydrographs of simulated sediment concentration generally have smaller peaks and longer recessions than do hydrographs of measured data....

K. L. Jenkins (compiler)
1989, Open-File Report 89-621
Water resources activities of the U.S. Geological Survey in Missouri consist of collecting hydrologic data and making interpretive studies. Hydrologic studies in Missouri are made through three basic types of projects: hydrologic data collection programs; local or areal hydrologic investigations; and statewide or regional studies. These projects are funded through...
Ground-water levels, water quality, and potential effects of toxic-substance spills or cessation of quarry dewatering near a municipal ground-water supply, southern Franklin County, Ohio
A. C. Sedam, S. M. Eberts, E. Scott Bair
1989, Water-Resources Investigations Report 88-4138
A newly completed municipal ground-water supply that produces from a sand and gravel aquifer in southern Franklin County, Ohio, may be susceptible to potential sources of pollution. Among these are spills of toxic substances that could enter recharge areas of the aquifer or be carried by surface drainage and subsequently...
Selected data describing stream subbasins in the Redwood River basin, southwestern Minnesota
D. L. Lorenz, G. A. Payne
1989, Open-File Report 89-405
This report presents selected data describing the characteristics of streams upstream from selected points on streams in the Redwood River basin. The points on the streams include outlets of subbasins of about five square miles, sewage treatment plant outlets, and U.S. Geological Survey gaging stations in the basin....
