This video describes how to perform automatic calibration of a HECHMS Model created for Cedar Creek watershed in Indiana. By watching this video you will learn how to: (1) Open an already created HECHMS Model; (2) Create optimization trial in HECHMS for model calibration; (3) Add parameters and their specifications to include in optimization; and (4) Run optimization trial and visualize calibration results.
