Sand transport and storage at New York Harbor mouth—Major sections of the New York-New Jersey shelf have been shaped by the tidal regimes associated with estuary mouths during the postglacial rise of sea level. Sand budgets of estuary mouths are also of great interest to environmental man- agers; the Atlantic coast estuaries are the approaches to the major coast ports and require repeated costly dredging. At pres- ent, the only estuary mouth subjected to systematic study is that of Chesapeake Bay (Ludwick 1972, 1974, in press). However, reconnaissance data are available for the Hudson estuary mouth, which suggest di- rections for further study. New York Harbor mouth is clearly a sink for the littoral drift of the Long Island and New Jersey coasts. Within the past century, much of the deposition has occurred on the ends of Rockaway and Sandy Hook spits; these features have grown rapidly, nearly closing off the harbor mouth within historic times (Shepard and Wanless 1971). However, it appears that much sand has bypassed the spits; a complex system of sand banks separated by interdigitating ebb and flood channels lies between them (Fig. 18). A profile of velocity residual to the semidiurnal tidal cycle gi-ves some indica- tion of the flow structure responsible for. 74°00' 73°55' Fig. 18.
