13. ABSTRACT (Maximum 200 words)
This report describes the ICETHK computer model that is used in conjunction with the HEC-2 backwater
model to simulate equilibrium ice jam profiles. The ICETHK model fulfills an important need in studies that
require the calculation of ice-jam-affected stage. This report presents the theory and limitations of ICETHK and
serves as a user's manual, and concludes with a discussion of river ice modeling using ICETHK.
