Abstract
The objective of this project is to improve the accuracy of the peak streamflow frequency estimates in ungauged streams by using a regionalization approach and the Bulletin 17B method of flood flow analysis. The entire state will be considered one region and the final results will be compared to previous studies done in the state. The data used will be the most up-to-date available from the USGS gauging stations around the state. This includes data from gauging stations that had less than 10 years of data when the last such study was conducted by Hodge & Tasker (1995). The data from a station will be used if that site contains more than 10 years of unregulated data. The resulting data will then be processed using the Bulletin 17B method and then by using least sum of squares regression analysis, the most accurate regression equation for specific frequencies will be calculated. An evaluation of the equations will be included with the final flood flow prediction equations. An evaluation of the HEC-SSP program and how it performs the Bulletin 17B analysis will be included with the final regression equations.
