ROLE OF CALIBRATION IN APPLICATION OF HEC-6

Calibration, the process of adjusting model parameters so that model results conform with observed prototype behavior, is an essential ingredient of any modeling effort, be it physical or mathematical. Calibration strategies for movable boundary numerical modeling (i.e., HEC-6) vary widely depending on the type and availability of field data and study scope and objective. The process of calibrating HEC-6 and interpreting field data and model results is described. Examples drawn from past project studies are used to illustrate important points. The theoretical and numberical limitations on extrapolation of model results beyond the calibration range are described. Sensitivity of model results to key input data is discussed. Applicability of HEC-6 to bridge design is addressed. The future research and development program for movable boundary mathematical modeling at the Hydrologic Engineering Center is also presented.
