Methodology of Evaluation of Forecasts of the Reservoir Ice Cover Thickness (the Votkinsk Reservoir Case Study)

K. D. Mikova and V. G. Kalinin

Relationships between the ice cover thickness alimentation and negative temperatures sums are defined for several ice profiles in the Votkinsk reservoir. Possibility of their using for the ice cover thickness forecasting is considered. Criteria of the acceptable errors of the ice cover forecasts and computations are studied. A new way of their improvement is proposed.
