Adapting a model of heat and mass exchange between a water body and the atmosphere taking into account the effect of shallows: Case study of the Ivankovo Reservoir.

The paper is based on a box model of heat and mass exchange with the incorporation of a block for calculating latent heat flux, supplemented by parameterization of heat and mass exchange between shallow water area and the atmosphere. The results of calculation of evaporation from the water area of the Ivankovo Reservoir, with allowance made for more intense evaporation from shallows, are given. The latent heat fluxes from shallow and deep-water zones of the water body are shown to differ, depending on weather conditions and water level; the increase in the evaporated-water volume due to taking into account the shallow-water effect is evaluated.
