Hydrologic models are developed to capture the dynamics of the hydrologic cycle and its various processes. Hydrologic models aim to depict various hydrologic phenomena by solving mathematical equations, where these equations are often simplified by making broad assumptions, particularly at larger watershed scales. However, due to the inherent complexities of the hydrological system, these equations cannot completely replicate the hydrologic cycle, constrained by limited knowledge, imprecise measurements (both boundary conditions and observed data), and challenges stemming from heterogeneous environments. Consequently, uncertainties abound in model predictions. Uncertainty analysis plays a crucial role in quantifying these unknowns within the system, showing the possible range of model outcomes.
