Technique for estimating magnitude and frequency of floods in Illinois Technique for estimating magnitude and frequency of floods in Illinois
A technique is presented for estimating flood magnitudes at recurrence intervals ranging from 2 to 500 years, for unregulated rural streams in Illinois, with drainage areas ranging from 0.02 to 10,000 square miles. Multiple regression analyses, using streamflow data from 241 sampling sites, were used to define the flood-frequency relationships. The independent variables drainage area...

Sediment transport to the Fox Chain of Lakes, Illinois Sediment transport to the Fox Chain of Lakes, Illinois
Two main tributaries to the Fox Chain of Lakes, the Fox River and Nippersink Creek, were sampled twice weekly and during periods of high runoff to determine the amount of suspended inorganic sediment being transported into the Chain of Lakes. Sediment yields were determined by using the transport-duration technique. It is estimated that 34,100 tons of suspended sediment are transported...

Water quality characteristics of six small lakes in Missouri: Mo. Dept. of Natural Resources. Water quality characteristics of six small lakes in Missouri: Mo. Dept. of Natural Resources.
A study of six small lakes, representative of those in the major physiographic regions of Missouri, shows variation in physical. chemical, and biological characteristics related to their location in the Slate. For example, because of climatic differences, ice cover and winter stratification are more prevalent in northern Missouri. Summer stratification lasts about one month longer in the...

Flood of June 27, 1975, in City of Ames, Iowa Flood of June 27, 1975, in City of Ames, Iowa
On June 27, 1975, the city of Ames and vicinity sustained severe flooding from Squaw creek and the south Skunk River. The storm which preceded the flood was net particularly outstanding in its intensity or duration. However, antecedent conditions plus the timing and direction of the storm were "ideally tuned" to cause the flood. In terms of magnitude of discharge as well as of damages...

Drainage areas for Illinois streams Drainage areas for Illinois streams
Drainage areas were tabulated for all streams in Illinois which drain over 100 square miles. at sites where streamflow data have been collected, and at other selected locations. Areas were planimetered on U.S. Geological Survey topographic quadrangle maps and balanced to known areas taken from Smithsonian Geographical Tables of areas of quadrilaterals of the earth's surface (procedures...
