Grain-size analyses of Ordovician sandstones from the Midwestern states
Keith Brindley Ketner
1979, Open-File Report 79-230
Certain Ordovician sandstones of the Midwestern States were investigated for the purpose of determining the range in size of constituent sand grains. Although many size analyses of the same formations have been reported in the literature, the methods of sample collection, preparation, and sieving were not uniform, and the results...
Hydrologic data for floods of July 1978 in Southeast Minnesota and Southwest Wisconsin
V.J. Latkovich
1979, Open-File Report 79-1166
Intense storms of July 1978 caused floods of historical significance in southeast Minnesota and southwest Wisconsin. Local, State, and Federal officials need data and information to evaluate, coordinate, and manage programs concerned with floods and flood losses. Because of a need to document stream discharges, elevations, and sediment concentrations, current-meter...
