Abstract The notion of convergent and transdisciplinary integration, which is about braiding together different knowledge systems, becoming the mantra numerous initiatives aimed at tackling pressing water challenges. Yet, transition from rhetoric to actual implementation impeded by incongruence in semantics, methodologies, discourse among disciplinary scientists societal actors. Here, we embrace “integrated modeling”—both quantitatively qualitatively—as a vital exploratory instrument advance such providing means navigate complexity manage uncertainty associated with understanding, diagnosing, predicting, governing human‐water systems. From this standpoint, confront barriers offering seven focused reviews syntheses existing missing links across frontiers distinguishing surface groundwater hydrology, engineering, social sciences, economics, Indigenous place‐based knowledge, studies other interconnected natural systems as atmosphere, cryosphere, ecosphere. While there are, arguably, no bounds pursuit inclusivity representing spectrum human processes around resources, advocate that integrated modeling can provide approach delineating scope through lens three fundamental questions: (a) What “purpose”? (b) constitutes sound “boundary judgment”? (c) are “critical uncertainties” their compounding effects? More broadly, call for investigating what warranted “systems complexity,” opposed unjustified “computational complexity” when complex human‐natural careful attention interdependencies feedbacks, scaling issues, nonlinear dynamics thresholds, hysteresis, time lags, legacy effects.
