Towards flexible, rich, and easy model coupling environments via CyberWater's open data and open model framework
Abstract
Comprehensive modeling tools have been of great importance to tackle critical efforts such as sustainable management of natural resources, monitoring of weather conditions, and forecasting of the flows of water and nutrients in the river network. This requires integration of diverse models from the atmospheric, hydrological, biological, environmental, to other models. Traditional approach on such model integration is complex and time consuming, especially with ever-increased model complexity and diversity and the heterogeneous data used by these models. To address such an urgent issue, the CyberWater framework is developed. This cyberinfrastructure is a collaborative NSF-funded project which offers a suite of Data Agents for accessing diverse data sources online and a generic model agent toolkit to ease model integration for users, all in a GUI-based workflow environment. In this study, we present our new development of the CyberWater modeling facilities to enable two-way model couplings in a seamless and easy-to-use workflow manner with no or limited coding, which can be applied to any two models already integrated into the framework. We will demonstrate these unique features through an example where the VIC model is coupled with the CASA-CNP model with model feedback via a two-way coupling in addition to the one-way coupling without the model feedback. Furthermore, CyberWater has been extended to allow for the integration of models that are structured with irregular modeling grid unit, which will be illustrated through the execution of the Iowa Hydrologic Model.
