Composable National Water Model Simulations Using the CyberWater Modeling Framework
Abstract
Evaluating scientific hypotheses within the water sciences related to health, resilience, and sustainability, requires researchers to estimate many Earth system phenomena including hydrological, environmental, biological, and atmospheric processes. These large and interdisciplinary topics often require more than one domain-specific computer model which are typically developed and used in isolation. In some cases, these model simulations require incompatible computing architectures and operating systems, e.g. Windows vs Linux. CyberWater, an ongoing effort to establish a sustainable approach to address these cyber infrastructural challenges, enables researchers and educators to build composable scientific model simulations that combine various data sources, computing architectures, and operating systems into a single reusable and configurable GUI-based workflow. The NOAA National Water Model (NWM) is an example of one such model that the Consortium of Universities for the Advancement of Hydrologic Science, Inc (CUAHSI) has been actively exploring methods for improving collaboration and accessibility, as well as lowering the barrier to entry. Specifically, CUAHSI has explored mechanisms for providing equitable access to the NWM's underlying parameter sets and spatial definition, commonly referred to as the hydrofabric. In this work, we explore how these efforts can be combined with the CyberWater modeling platform to construct reusable simulations of the NWM that is also fully reproducible. We present the technical design of the software agents for collecting forcing data, collecting domain hydrofabric, data regridding, and model simulation, as well as outline areas for future work and collaboration.
