This Coastal and Hydraulics Engineering Technical Note CHETN describes the Eastcoast 2001 computed database of tidal elevation and velocity constituents. This database was developed to allow surface-water elevation and currents to be quickly and easily defined in open waters within the Western North Atlantic Tidal WNAT domain. The WNAT domain encompasses the Western North Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. The Eastcoast 2001 database defines the computed elevation and velocity amplitude and phase for the O1, K1, Q1, M2, S2, N2, and K2 astronomical tidal constituents as well as the steady, M4 and M6 overtides. This CHETN summarizes the development of the Eastcoast 2001 tidal constituent database, presents global, basin-specific and site-specific error estimates, and discusses exactly what is computed, where it can be applied, and how it can and should be used. Limitations of the database are also described.
