Book Description
To evaluate the effects of the 1993 flood in the upper Mississippi River Basin on the determination of flood magnitude and frequency, discharges that had recurrence intervals of 10, 25, 50, and 100 years computed from data through the 1992 water year were compared with those computed from data through the 1993 water year for 62 selected streamflow-gaging stations in Iowa. On the basis of the flood-frequency analysis computed from data through the 1993 water year, a flood that was greater than or equal to a 10-year recurrence-interval discharge occurred during 1993 at all 62 gaging stations, and a flood greater than or equal to a 100-year recurrence-interval discharge occurred at 11 of the gaging stations.

Book Description
In June 2008, the rivers of eastern Iowa rose above their banks to create floods of epic proportions; their amazing size—flowing in places at a rate nearly double that of the previous record flood—and the rapidity of their rise ruined farmlands and displaced thousands of residents and hundreds of businesses. In Cedar Rapids, the waters inundated more than nine square miles of the downtown area; in Iowa City, where the flood was also the most destructive in history, the University of Iowa’s arts campus was destroyed. By providing a solid base of scientific and technical information presented with unusual clarity and a wealth of supporting illustrations, the contributors to this far-reaching book, many of whom dealt firsthand with the 2008 floods, provide a detailed roadmap of the causes and effects of future devastating floods. The twenty-five essays fall naturally into four sections. “Rising Rivers, Spreading Waters” begins by comparing the 2008 floods with the midwestern floods of 1993, moves on to trace community responses to the 2008 floods, and ends by illuminating techniques for forecasting floods and determining their size and frequency. “Why Here, Why Now?” searches for possible causes of the 2008 floods and of flooding in general: annual crops and urban landscapes, inflows into and releases from reservoirs, and climate change. “Flood Damages, Flood Costs, Flood Benefits” considers the complex mix of flood costs and effects, emphasizing damages to cities and farmlands as well as potential benefits to natural communities and archaeological sites. “Looking Back, Looking Forward” lays out approaches to managing the floods of the future that are sure to come. While the book draws most of its examples from one particular region, it explains flooding throughout a much larger region—the midwestern Corn Belt—and thus its sobering yet energizing lessons apply well beyond eastern Iowa. By examining the relationships among rivers, floodplains, weather, and modern society; by stressing matters of science and fact rather than social or policy issues; and by addressing multiple environmental problems and benefits, A Watershed Year informs and educates all those who experienced the 2008 floods and all those concerned with the larger causes of flooding.

Book Description
From warning the public of impending floods to settling legal arguments over water rights, the measurement of streamflow ("streamgaging") plays a vital role in our society. Having good information about how much water is moving through our streams helps provide citizens with drinking water during droughts, control water pollution, and protect wildlife along our stream corridors. The U.S. Geological Survey's (USGS) streamgaging program provides such information to a wide variety of users interested in human safety, recreation, water quality, habitat, industry, agriculture, and other topics. For regional and national scale streamflow information needs, the USGS has created a National Streamflow Information Program (NSIP). In addition to streamgaging, the USGS envisions intensive data collection during floods and droughts, national assessments of streamflow characteristics, enhanced information delivery, and methods development and research. The overall goals of the program are to: meet legal and treaty obligations on interstate and international waters, support flow forecasting; measure river basin outflows, monitor sentinel watersheds for long-term trends in natural flows, and measure flows for water quality needs. But are these the right topics to collect data on? Or is the USGS on the wrong track? In general, the book is supportive of the design and content of NSIP, including its goals and methodology for choosing stream gages for inclusion in the program. It sees the ultimate goal of NSIP as developing the ability to use existing data-gathering sites to generate streamflow information with quantitative confidence limits at any location in the nation. It is just as important to have good measurements during droughts as during floods, and it therefore recommends supporting Natural Resource Conservation Service forecast sites in addition to those of the National Weather Service.
