    "descript": "A process-based numerical model of the mouth of the Columbia River (MCR) and estuary, Oregon and Washington, was applied to simulate hydrodynamic conditions for the time period of the Office of Naval Research-funded River and Inlets Dynamics (RIVET II) field experiment conducted between May 9 and June 15, 2013.  The model application was constructed using Delft3D, an open-source software package used to solve the unsteady shallow water equations to simulate water motion due to tides, waves, wind, and buoyancy effects. This portion of the USGS data release describes the model application for this experiment and presents input files necessary to run the Delft3D model, as well as selected output from the model simulation.",

Distributions are observations of tidal height, currents, and cycles, at specific locations and times, and they include maps of tidal climatology based on combinations of observations, astronomy, hydrodynamic theory, and numerical models. Assessments evaluate tidal energy potential, technologies, and risks; model the effects of tides on other uses; and evaluate risks associated with extreme tides. Predictions are the results of models or projections of future tidal climatology, tidal energy potential, effects, and risks; these data include predicted changes due to economic, regulatory, technological, and environmental changes."

Distributions are records of currents, physical properties, or biogeochemical water properties, often based on shipboard surveys or coastal monitoring programs, and maps of currents or water property climatology, which indicate the expected locations of features under present conditions or apply a classification structure like that of CMECS. Assessments are data that provide information about the ecological or economic values, impacts, drivers, connections, or functions of water column features in their present distributions. Predictions are the results of models projecting future changes to currents or other persistent oceanographic features (for example, clines, stratification, connectivity, linkages, and zones of separation) due to climate change, ice-cap melt, and changing freshwater inputs; models predicting the ecological or economic impacts of these changes; and scenario-testing models comparing ecological or economic outcomes of different management actions."
