Accurate streamflow predictions are essential for a large number of applications, including flood forecasting and the management of water resources, and water quality. Satisfactory estimation of the energy fluxes from the land surface that feed back to the atmosphere is an important component in climate and weather forecasting. Interactions between hydrology and climate are extremely important in relation to long-term water resources planning. Water and energy are the mechanisms that explain the complex interactions between the land surface and the atmosphere.

520 $a Accurate streamflow predictions are essential for a large number of applications, including flood forecasting and the management of water resources, and water quality. Satisfactory estimation of the energy fluxes from the land surface that feed back to the atmosphere is an important component in climate and weather forecasting. Interactions between hydrology and climate are extremely important in relation to long-term water resources planning. Water and energy are the mechanisms that explain the complex interactions between the land surface and the atmosphere.
520 $a To analyze the coupled water and energy budgets in a basin, Surface-Vegetation-Atmosphere Transfer (SVAT) schemes and hydrological models with different levels of complexity are linked. It would be reasonable to expect that the theoretical accuracy of the more sophisticated SVAT hydrological models would lead to improved accuracy. This topic is the main investigation of this research.
520 $a The study here reported shows a comparison of three models with different levels of complexity. Two are based on SVAT schemes, namely, the Canadian Land Surface Scheme (CLASS) and the Interactions Soil-Biosphere-Atmosphere (ISBA) land surface scheme linked with the hydrological model WATFLOOD (i.e., WATISBA and WATCLASS). The third is the WATFLOOD model itself.
520 $a The three models are compared in a data-rich environment using the hydrometeorological information collected during the Boreal Ecosystem-Atmosphere (BOREAS) study, which took place between 1994 and 1996 in Saskatchewan and Manitoba in Canada. Data for two study areas, the Northern Study Area (NSA) near Thompson, Manitoba, and the Southern Study Area (SSA) north of Prince Albert, Saskatchewan, are used to calibrate and validate the models.
520 $a The goal of the comparison was to investigate the level of complexity necessary to obtain in small watersheds (representative of the grid cell size in atmospheric models) a good agreement between the evapotranspiration, soil moisture, snowpack, and energy flux simulations, and the point scale measurements at different flux tower sites, as well as the streamflow at time scales of one hour and above. To accomplish this goal, one of the main components of this investigation is to develop the "off line" linkage between the WATFLOOD hydrological model and the version of the ISBA SVAT scheme implemented in the Canadian Numerical Weather Forecast Model at Environment Canada (ISBA-CMC).
