Role of Calibration in the Application of HEC-6.

Abstract

HEC-6 (6) is a one-dimensional movable boundary open channel flow model designed to simulate streambed profile changes over fairly long time periods (typically years). Calibration, the process of adjusting model parameters such 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(6)) vary widely depending upon type and availability of field data and study scope and objective. This paper describes the process of calibrating HE-6, and interpretation of field data and model results. Examples drawn from past project studies are used to illustrate important points. The theoretical and numerical limitations on the extrapolation of model results to key input data and its applicability to bridge design are also discussed.
