The Joint Federal Interagency Conferences on Sedimentation and Hydrologic Modeling (SEDHYD) conference was held June 24–28, 2019, at the Peppermill Hotel in Reno, Nevada. The conference provides formal technical presentations, poster sessions, field trips, workshops, exhibits and model demonstrations.
David Neumann of CADSWES presented a co-authored paper, “River and Reservoir Operations using RiverWare within the Corps Water Management System (CWMS).”
RiverWare, a planning and operations modeling tool, is used by a number of USACE Districts for detailed multi-objective management of river and reservoir systems. For near-real time operations applications, RiverWare models are integrated into the suite of models, analysis and database tools provided by the Corps Water Management System (CWMS), such as: HEC-MFP for simulating precipitation; HEC-HMS for modeling rainfall-runoff; HEC-RAS for detailed hydraulic analysis; and HEC-FIA for flood impact analysis. CWMS features a sophisticated control and visualization interface (CAVI) with a GIS integrated with model schematics, allows evaluation of operational alternatives, and manages data inputs, outputs and inter-model data transfers via a database. The CWMS architecture allows additional non-USACE models and customized computational tools to be tightly integrated via plugins; USACE-Southwest Division has sponsored the integration of RiverWare into CWMS via this plugin mechanism. The RiverWare plugin allows RiverWare model objects, plots and data to be displayed in the CAVI, RiverWare models to be run in full integration with the other CWMS applications and database, and access to the native RiverWare software if needed.
This paper details the implementation of RiverWare models in the CWMS framework, including data connections, data aggregation and disaggregation and the operator interaction with the tools. We will illustrate the features and functionality in a case study of a USACE model, the White River in Arkansas and Missouri, developed by Little Rock District. These models are used in the CWMS framework to assist water managers in making critical decisions on a day-to-day and hour-by-hour basis.
RiverWare is developed by the University of Colorado Center for Advanced Decision Support for Water and Environmental Systems (CU-CADSWES), under sponsorship of the Tennessee Valley Authority (TVA), U.S. Bureau of Reclamation (USBR), and U.S. Army Corps of Engineers (USACE) and distributed by the University of Colorado Office of Technology Transfer.
David also provided a RiverWare Interactive Scenario Explorer (RiverWISE) demonstration. Read the Extended Abstract.
