  • Rivers, Estuaries, Deltas - Woods Hole Oceanographic Institution
    As sediment builds up along the bottom of an estuary, it begins to form a delta Continued accumulation of sediment can build land well beyond the mouth of the river Deltas most often form when the sediment-rich river empties into a protected area, behind a reef, barrier island, seasonal sea ice, or into a small body of water, such as a gulf
  • Effects of winds on stratification and circulation in a partially mixed . . .
    down-estuary and up-estuary winds, but stratification experiences larger reduction and takes longer to recover under up-estuary winds In the presence of rotational effects, wind-driven lateral circulations cause the lateral straining of density field and weaken the shear in the along-channel flows Under the down-estuary winds, a counterclockwise

    well-defined subterranean estuary (Waquoit Bay, MA, USA), these two articles will provide an in-depth study of the major biogeochemical reactions operating on the permeable sedi-ments of a coastal aquifer with active Fe and Mn redox cycles and well-defined salinity gradients 2 STUDY AREA Waquoit Bay is a shallow semi-enclosed estuary located on
  • Where the Rivers Meet the Sea - Woods Hole Oceanographic Institution
    Slowly, the estuary grows muddier and muddier, shallower and shallower Occasionally a major flood will push the salt right out of the estuary, carrying the muddy sediment along with it Sediment cores in the Hudson River indicate that sediment may accumulate for 10, 20, or even 50 years, laying down layers every year like tree rings
  • Turbulent mixing in a strongly forced salt wedge estuary
    upper estuary, the channel is narrow with a series of sills (typical depth of 4–6 m) and deeper holes (typical depth of 8–10 m) (Figure 1) Between 1 5 and 5 km from the mouth the estuary broadens into an embayment with intertidal flats and fringing salt marsh The channel at the mouth passes between barrier islands and is constrained by

    in the lower ETM remained up-estuary (Geyer et al 2001; Woodruff et al 2001) During the moderate freshet of 2001, sediment flux in the lower ETM was down-estuary at maximum discharge and then turned up-estuary during lower discharge summer months (Traykovski et al 2004) The goal of this work is to quantify the effects of
  • Wind-driven lateral circulation in a stratified estuary and its effects . . .
    mixed stratified estuary, Li and Li [2011] investigated how the wind-driven lateral circulation causes the lateral straining of density field and how this lateral straining off-sets the effects of longitudinal straining to reduce the stratification-reduction asymmetry between the down- and up-estuary winds This is a companion paper where we
  • pH-Dependent iron oxide precipitation in a subterranean estuary
    acteristics of the subterranean estuary in Waquoit Bay play a minor role in the removal of Fe(II) Because of the enhanced precipitation of Fe oxides, more ground-water APO 4 is removed when the pH dependency of the precipitation of Fe oxides is considered (Fig 3) 5 Conclusions Using a 1D RTM, applied to a groundwater flow
