Balancing the Water Budget: A Physical Basis for Quantifying Water Fluxes Using Data and Models





Session ID#: 24458

Session Description:
Mass balance is the governing principle in the characterization hydrologic processes. The water budget, ΔStorage = Input – Output, is a “first principles lens” that can be used to guide exploration, observations, and process representation of hydrologic fluxes. Furthermore, it constitutes the framework in which we integrate and evaluate hydrologic models at multiple spatio-temporal scales (from single events to multi-decadal cycles, and from watersheds to continents). Given its fundamental importance, an important question is to what degree and with how much confidence can the water budget be balanced. This session solicits studies exploring this question at multiple spatial and temporal scales using both data-driven and model-based approaches. We especially welcome efforts to incorporate a broad understanding of conservation of mass into the evaluation or integration of hydrologic models. Improved system-wide understanding is paramount as the globalization of water and trade of “virtual” water stocks become the status quo.
