Estimating low-flow frequency for perennial Missouri Ozarks streams
John Skelton
1974, Water-Resources Investigations Report 73-59
A linear regression model, utilizing an independent variable described as the flow area of a stream, has been developed for use in estimating minimum streamflow at ungaged sites in the Ozarks region of Missouri. The basic premise in the method is that low-flow characteristics at any point on perennial Ozarks...

Erosion and sediment yields in mountain watersheds of the Transverse Ranges Ventura and Los Angeles Counties, California; analysis of rates and processes
Kevin M. Scott, Rhea P. Williams
1974, Water-Resources Investigations Report 73-47
Major-storm and long-term erosion rates in mountain watersheds of the western Transverse Ranges of Ventura County are estimated to range from low values that will not require the construction of catchments or channel-stabilization structures to values as high as those recorded anywhere for comparable bedrock erodibilities.A major reason for this...
Flood profiles and inundated areas along the White River, Chelan County, Washington

1974, Water-Resources Investigations Report 74-13
Flood profiles covering the main stem to river mile 11.0 (kilometer 17.7) of the White River in Chelan County, Wash., were developed in a 3-year field study (1970-72) in cooperation with the State of Washington Department of Ecology. Flood-frequency curves based on an average of a regional computation and a...
