EVALUATION OF HYDROLOGIC ANALYSIS PROCEDURES USED BY KDOT, VOLUME 1. FINAL REPORT

This project had two objectives. The first objective was to update the Kansas Department of Transportation's (KDOT's) rainfall intensity tables by incorporating the most recent rainfall-frequency data from the National Weather Service. The second objective was to evaluate the procedures used by KDOT to estimate flood discharges, more efficient review of hydrologic studies, or better coordination with other engineering organizations and regulatory agencies. The report explains how new rainfall intensity tables were developed and reviews the rational method for peak discharge, with emphasis on estimation of runoff coefficients and times of concentration. The reliability of flood estimates derived from stream-gaging records was examined. The reliability of the USGS and FENL-H regression equations for peak discharge was evaluated. The fundamentals of flood-hydrograph simulation, with emphasis on design storms, infiltration, and surface runoff were examined. Examination and comparison of the computer programs most often used for flood-hydrograph simulation were made. The TR-55 methods of the U.S. Soil Conservation Service, two simple methods for the development of design hydrographs and several methods for the analysis and design of detention sites were examined. A second volume contains the new rainfall intensity tables developed by the project.
