HYDROMODELER: A MODELING PLUG-IN FOR THE CUAHSI HIS HYDRODESKTOP APPLICATION

HydroModeler is a plug-in application that extends the core HydroDesktop application to support hydrologic modeling. HydroDesktop is a client application for the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) Hydrologic Information System (HIS) designed to allow users to identify and gather data served through the HIS. HydroModeler makes use of the Open Modeling Interface (OpenMI) standard and OpenMI Association Technical Committee (OATC) Software Development Kit (SDK) to provide a "plug-and-play" modeling framework within HydroDesktop. By adopting the OpenMI standard and by leveraging core HydroDesktop functionality for data management and visualization, HydroModeler is able to focus on the more specific task of running integrated model configurations. As more models are refactored to follow the OpenMI standard, we anticipate that HydroModeler will become an increasingly powerful application for hydrologic and water resource modeling. We will discuss the design and implementation of HydroModeler and demonstrate its application with a case study.
