| Abstract | Understanding carbon fluxes at the watershed scale is essential for sustainable environmental strategies. Conventional models often overlook hydrological connectivity and lateral carbon transport, limiting their ability to represent coupled water carbon dynamics. To overcome these limitations, the WISE (Watershed-based Integrated Simulator for the Environment) model is introduced as a novel, spatially explicit, process-based framework that integrates hydrology, soil erosion, terrestrial, and aquatic carbon processes. WISE delineates georeferenced simulation units with explicit hydrological connectivity, enabling detailed tracking of vertical and lateral carbon fluxes, including interception and transformation in reservoirs, wetlands, and impounded waters. Applied to the Sam Ngao Watershed (SNgW) in Thailand, sensitivity analysis confirmed that incorporating water body interception significantly improved model accuracy. WISE achieved strong calibration (KGE = 0.78, R² = 0.93, NSE = 0.76, PBIAS = 9.21%) and robust validation (KGE = 0.72, R² = 0.81, NSE = 0.66, PBIAS = -7.46%). These findings highlight the importance of hydrological connectivity in shaping watershed carbon fluxes and demonstrate WISE’s potential as a decision support tool for integrated watershed management, climate change adaptation, and ecosystem resilience. |
