Definition
Usually sets toward the head of an estuary or up-channel, but the correlation with rising water is not exact: in many channels the stream continues to run for an appreciable time after high water because it is driven by the horizontal pressure gradient of the progressing tidal wave rather than by local water level. Always take the stream from a tidal atlas or diamond, not from an assumption about high water.
