Ice Engineering: Method to Estimate River Ice Thickness Based on Meteorological Data

摘要

Estimates of ice cover thickness are often necessary for hydraulic analyses of ice-affected rivers or for design of bridges or other riverine structures. Although ice cover formation and growth can be a highly complex and variable process, estimates of ice cover thickness can be made using meteorological data. The modified Stefan equation is suitable for use in estimating ice thickness in many cases. Whenever possible, the estimated ice thickness at a particular site should be compared to actual ice thickness observations to evaluate the reasonableness of the coefficients given the physical processes.
