This thesis describes the simulation of evaporation from a wetland lichen and moss tundra in Churchill, Manitoba. -- The models used are the Canadian Land Surface Scheme-CLASS and the Penman-Monteith model. In both models, the canopy resistance needs to be corrected to account for non-vascular vegetation, whose evapotranspiration depends only on canopy moisture. The plotted results show that both the modified models perform comparably in the simulation of the evaporation. -- The data for the simulations are from two weather stations in Churchill: Fen and Rail Spur. All the components of the energy balance are modelled at Fen, and the results from CLASS show good fits to the measurements. Longwave radiation is successfully modelled at Rail Spur by associating the degree of cloud cover with weather conditions.
