N1 - Funding Information:
The development and testing of ELCIRC has greatly benefited from the contributions of many colleagues. Through both his published work and informal conversations with the second author in workshops in Denver and Delft, Prof. Vincenzo Casulli provided the conceptual foundation on which we built ELCIRC. Within the CORIE team, we are particularly grateful to Dr. Mike Zulauf for developing air–water exchange modules (see Appendix A); Dr. Arun Chawla for extended discussions on formulation and simulation quality; and Mr. Paul Turner for the creation of supporting pre- and post-processing tools. We are also grateful to Dr. Edmundo Casillas, of the National Oceanic and Atmospheric Administration (NOAA), for providing the driving application and partially facilitating the funded development of ELCIRC. ELCIRC has been developed through a combination projects funded by NOAA and the Bonneville Power Administration (NA17FE1486, NA17FE1026, NA87FE0405), the US Fish and Wildlife Service (133101J104), the Office of Naval Research (N00014-00-1-0301, N00014-99-1-0051), and the National Science Foundation (ACI-0121475). Finally, we would like to thank early beta-testers of ELCIRC, who include CCALMR students Sergey Frolov, Michela Burla and Marina Vantrease; Dr. Mike Foreman (Institute of Ocean Sciences, Canada); and Drs. Anabela Oliveira and André Fortunato (Laboratório Nacional de Engenharia Civil, Portugal). SAR images ( Figs. 1a, c ) were purchased by Dr. Todd Sanders, under NOAA NESDIS Grant NA16EC2450.

N2 - Challenges posed by the Columbia River estuary-plume-shelf system have led to the development of ELCIRC, a model designed for the effective simulation of 3D baroclinic circulation across river-to-ocean scales. ELCIRC uses a finite-volume/finite-difference Eulerian-Lagrangian algorithm to solve the shallow water equations, written to realistically address a wide range of physical processes and of atmospheric, ocean and river forcings. The numerical algorithm is volume conservative, stable and computationally efficient, and it naturally incorporates wetting and drying of tidal flats. ELCIRC has been subject to systematic benchmarking, and applied to the description of the Columbia River circulation. This paper motivates and describes the formulation, presents and critically analyzes the results of selected benchmarks, and introduces ELCIRC as an open-source code available for community use and enhancement. A companion paper describes the application of ELCIRC to the Columbia River.
