Characteristics of four urbanized basins in south Florida

Physical characteristics of four urbanized basins in south Florida are presented. Land use of the four basins are low-density residential, highway, commercial, and high-density residential. Maps of each basin include a photomosaic, a sewerage map, a drainage map, and an impervious-area map. Tabular data include pervious and impervious areas; sewer data, such as pipe diameter, length, and slope; and inlet elevations. General descriptions of the soil cover and type, vegetation, streets, gutters and curbs are also provided.

Uranium-isotope variations in groundwaters of the Floridan aquifer and Boulder Zone of south Florida

Water samples from four wells from the main Floridan aquifer (300-400 m below mean sea level) in southeast Florida exhibit 234 U 233 U activity ratios that are significantly lower than the secular equilibrium value of 1.00. Such anomalous values have been observed previously only in waters from sedimentary aquifers in the near-surface oxidizing environments. These four wells differ from six others, all producing from the same general horizon, in being located in cavernous highly transmissive zones. We hypothesize that the low activity ratios are indicative of a relic circulation pattern whereby water from the surface aquifer was channelled to lower levels when sea level was much lower. At a deeper cavernous level, known as the Boulder Zone (800-1,000 m below mean sea level), the U isotopes, along with other chemical constituents, show progressive changes with increasing distance from an inferred flow source in the Straits of Florida. This tends to support the hypothesized landward flow (though with a more northerly component) of cold seawater in the extensively transmissive Boulder Zone.

Florida submergence curve revised: Its relation to coastal sedimentation rates

New data substantiate as well as modify the south Florida submergence curve, which indicates that eustatic sea level has risen continuously, although at a generally decreasing rate, during the last 6500 to 7000 sidereal years (5500 standard radiocarbon years) to reach its present position. Accumulation rates of coastal deposits are similar to the rate of sea-level rise, thus supporting the generalization that submergence rates largely determine as well as limit rates of coastal sedimentation in lagoonal and estuarine areas.
