Sensitivity of soil hydraulic property on the simulation of hydrological fluxes in the Interior Alaska boreal forest ecosystem

This study tested the sensitivity hydrological simulation to variations in residual soil moisture content in the contrasting sub-basins of the Caribou Poker Creek Research Watershed (CPCWR) – the C2 (low permafrost) and C3 (high permafrost) sub-basins. In this study, we demonstrated that the basin a...

Description
Summary:This study tested the sensitivity hydrological simulation to variations in residual soil moisture content in the contrasting sub-basins of the Caribou Poker Creek Research Watershed (CPCWR) – the C2 (low permafrost) and C3 (high permafrost) sub-basins. In this study, we demonstrated that the basin average and spatially distributed simulations of runoff, evapotranspiration and soil moisture content are sensitive to small variations in the residual soil moisture content, and the sensitivity varies in both space and time. Dry areas and periods of low soil moisture are more sensitive compared to moist areas. Compared to other hydrological processes including direct runoff and evapotranspiration, baseflow in dry areas is the most sensitive water balance component. As its effect is critical on the evaluation of the impacts of warming, further evaluation and parameterization of residual soil moisture content in different land surface models is important. In this archive, model input forcing data and output fluxes and figures of the primary results are included. Details about the data, modeling, and figure can be found in the PhD dissertation' DEVELOPMENT OF A PARAMETERIZATION FOR MESOSCALE HYDROLOGICAL MODELING AND APPLICATION TO LANDSCAPE AND CLIMATE CHANGE IN THE INTERIOR ALASKA BOREAL FOREST ECOSYSTEM' by Abraham Endalamaw, University of Alaska Fairbanks.
