To review existing data assimilation methods in hydrology and formulate a systematic, integrated framework that characterizes and minimizes predictive uncertainty.
Conducted a systems-perspective review of data assimilation methods applied across hydrological state estimation, parameter estimation, and system identification.
Assessed implementation challenges, conceptual limitations, and the lack of unified procedural guidelines across diverse hydrological prediction settings.
Identified that current hydrologic uncertainty methods lack cohesive, standardized guidelines for implementation across variable environmental decision-making settings.
Formulated an integrated, hierarchical data assimilation framework designed to progressively constrain uncertainty across state, parameter, and system levels.
