Conceptual study develops a hydrological framework for knowledge loss in aerospace and defense environments, highlighting mechanisms of organizational amnesia and critical knowledge erosion.
Prevailing Knowledge Management (KM) models offer limited support for detecting Critical Knowledge erosion before it compromises strategic resilience. This study proposes the Hydrological Model of Knowledge Dynamics for Science, Technology, and Innovation (ST&I) , a systemic artifact that represents knowledge flows, stocks, losses, and governance controls in ST&I environments. Based on literature review, bibliometric analysis, and field observation in the Brazilian Aerospace and Defense sector, the model formalizes a functional isomorphism between hydrological and Dynamic Knowledge Management (DKM) processes. The propositions, framed as hypotheses for future empirical validation, explain how organizational amnesia may emerge from attrition‐driven drainage, obsolescence‐related evaporation, crisis‐driven outflow, and monitoring failures. The article also distinguishes Essential Knowledge from Critical Knowledge as knowledge‐stock categories requiring different governance logics. Rather than claiming empirically validated effects, the study provides a structured conceptual lens for examining knowledge vulnerability and supporting diagnostic routines in volatile, high‐complexity sectors.
