Abstract: The application of integrated hydrologic models to large regional and continental domains has expanded greatly in recent years. High resolution groundwater surface water models have provided novel insights into watershed dynamics across a range of spatial scales. Increasingly, our community is working to better integrate subsurface processes into land surface and atmospheric models. Today I will talk about progress developing a national integrated hydrologic model including an overview of dataset development, modeling approach and platform advances. While this is important progress, one of the key gaps remaining in many physically based simulations is the representation of human operations. The second part of my talk will cover next steps to better understand represent large human systems in this framework. I will present work to map the impact of reservoirs on our national river networks. This includes research to explore river bifurcation nationally including tens of thousands of storage structures, as well as work to develop a new national database of historical reservoir operations and derived operating policies.

Abstract: The role of individual and collective human agency is increasingly recognized as a prominent and arguably paramount determinant in shaping the behavior, trajectory, and vulnerability of water systems. However, the representation of human action in integrated water system models varies widely across methodological approaches, potentially leading to disjointed insights drawn from human-water system modeling research. We present a new typology for classifying how human actors are represented in the wide array of integrated human-water system models applied in research and practice. The typology consists of three key components, each corresponding o a simple question: 1) Who are the actors in human-water system models? 2) What are their modeled actions? 3) How and for what purpose are these actors and actions operationalized in a model? The typology is applied to two distinct water system modeling efforts, the Jordan Water Model (JWM) and MOSART-WM-ABM, illustrating its utility in characterizing and comparing diverse integrated human-water systems modeling approaches.
