Book excerpt: Determining discharge in a stream is important to the design of culverts, bridges, and other structures pertaining to transportation systems. Currently in Utah regression equations exist to estimate recurrence flood year discharges for rural watersheds greater than 30 mi2, and the rational method is used for areas smaller than 0.5 mi2, however, there are no good methods available to estimate discharges for rural watersheds that fall between the two approaches. To solve this issue, flood frequency analyses were conducted for small rural watersheds with streamflow gaging station data within the state of Utah to develop regression equations for estimating flood flows for mid-sized watersheds. The watersheds selected range from 0.5 mi2 to 30 mi2, and have at least 10 years of annual peak discharges recorded by the United States Geological Survey (USGS). Flood frequency analyses were performed in accordance with the guidelines of Bulletin 17B (Interagency Advisory Committee on Water Data), using the USGS computer program PeakFQ (Flynn et al 2006). Computed flood year streamflows were regressed against multiple parameters (watershed geometries, soil characteristics, precipitation data, land use data, etc.) to estimate different recurrence flood year flows (i.e. 2-, 5-, 10-, 25-, 50-, 100-, 200-, 500-year). Regression equations were developed for seven regions in the state of Utah delineated according to hydrologic regions or climatic properties. Regression equations were developed in the format of the rational method where the runoff coefficient was regressed against appropriate determined data: basin characteristics, such as drainage basin area, max flow distance, sinuosity, composite curve number, saturated hydraulic conductivity, and climatic characteristics including, the basin centroid 2-year 24-hour precipitation, and basin centroid mean annual precipitation. The regression equations are presented within the document including errors associated with the regression processes. This document also summarizes the procedures a user should follow to use these equations in practice. Cautions are presented for the user to understand the limitations of the equations and to facilitate more efficient design of channel crossings.

Book excerpt: Floods constitute a persistent and serious problem throughout the United States and many other parts of the world. They are responsible for losses amounting to billions of dollars and scores of deaths annually. Virtually all parts of the nation--coastal, moun tainous and rural--are affected by them. Two aspects of the problem of flooding that have long been topics of scientific inquiry are flood frequency and risk analyses. Many new, even improved, tech niques have recently been developed for performing these analyses. Nevertheless, actual experience points out that the frequency of say a IOO-year flood, in lieu of being encountered on the average once in one hundred years, may be as little as once in 25 years. It is therefore appropriate to pause and ask where we are, where we are going and where we ought to be going with regard to the technology of flood frequency and risk analyses. One way to address these ques tions is to provide a forum where people from all quarters of the world can assemble, discuss and share their experience and expertise pertaining to flood frequency and risk analyses. This is what con stituted the motivation for organizing the International Symposium on Flood Frequency and Risk Analyses held May 14-17, 1986, at Louisiana State Universj. ty, Baton Rouge, Louisiana.
