Abstract
Understanding the carbon dynamics of the boreal forests often relies on the understanding the hydrological processes. The TRIPLEX Model incorporates several fundamental submodels that describe the water, nutrients and plant biomass relationships in forest ecosystems. To simulate hydrological processes, water balance and their interactions with carbon dynamics is a desirable step in designing projects in or near forested wetlands by using the TRIPLEX model. The purpose of this research was to develop a submodel for the TRIPLEX1.0 model system to simulate hydrological processes, hydroperiods and wetland interactions with aquifers. This submodel is capable of simulating flow routing, export and import of water, and evapotranspiration from forested wetlands for different hydroperiods. The model calculates a water balance based on precipitation, snowmelt, evaporation and transpiration from the forest canopy, evaporation from the understory and soil, surface runoff, water infiltration, diffusion, bypass flow, drainage and subsurface flow on a daily time-step. The ground water flow model was used to reproduce the surface water flow process through wetlands, and then to estimate new flow rates and values. The results are used to explore the interaction between water table positions, vertical soil moisture fluxes using by TRIPLEX to simulate carbon dynamics. The response and sensitivity of hydrology and soil carbon predictions to changes in model inputs, using both univariate and simultaneous changes in multivariable were examined in this study.
