INFORMATION NEEDS FOR THE PROPER APPLICATION OF HYDROLOGIC REGIONAL REGRESSION EQUATIONS

Regional regression equations are used by many state and local agencies to estimate flood characteristics used in the design of drainage structures. The regression equations are preferred by many users because of their relative accuracy, simplicity (i.e., ease of application), and replicability. However, the experience of the Ohio Department of Transportation (ODOT) indicates that some problems do exist in applying the equations. The problems are caused in part by the disparity in background of report writers and users and in part by limitations of the equations. The experience of ODOT is used to demonstrate some of the potential misapplications of regional regression equations, and some of the information that has been given to designers to clarify the application of the equations is presented.
