Effects of tidal current phase at the junction of two straits
Estuaries typically have a monotonic increase in salinity from freshwater at the head of the estuary to ocean water at the mouth, creating a consistent direction for the longitudinal baroclinic pressure gradient. However, Mare Island Strait in San Francisco Bay has a local salinity minimum created by the phasing of the currents at the junction of...

The authors have used color stereo photos along with a three-dimensional visualization photogrammetric software package, Socet Set, to produce orthophotometric-corrected mosaics of St. Croix, St. John, and St. Thomas in the U.S. Virgin Islands. These mosaics are used for numerous applications such as characterization of the shallow water benthic...

Warner, John C. Sediment transport pathway in the back of a nearly semienclosed subembayment of San Francisco Bay, California
Time series measurements of current velocity, depth and suspended-solids concentration (SSC) were used to obtain suspended-solids fluxes (SSF) during the fall at central Honker Bay and Spoonbill Creek. A wind-induced shear stress increases SSF out of Honker Bay through Spoonbill Creek by combining two effects: (1) wind-wave resuspension of bed...

Hydrologic evaluation of a hypothetical coal-mining site near Chrisney, Spencer County, Indiana
Protecting the water resources of the Nation is a major emphasis of the Surface Mining Control and Reclamation Act, PL 95-87. Permanent regulations established for this Act by the Office of Surface Mining (OSM) require the issuance of a permit before mining begins. An application for a mining permit must include an assessment of the hydrologic...
