From introduction: This report describes some basic principles of hydrology as they apply to Martin County. The major land features of the county are described first, then the hydrologic cycle and the county's surface-water and ground-water resource. Specific problems associated with population growth and the county's development, such as saltwater intrusion and water use, are sited and sections have been included in the report to deal with these problems.

This evaluation presents a proposal to drill more new wells away from the Atlantic Coast to avoid saltwater intrusion problems in the existing freshwater wells. It contains figures and maps.

This report presents results of a model evaluation for four estuaries in Pasco, Citrus, and Pinellas counties, Florida. It includes graphs, tables, and graphs.

Purpose and scope: This reports presents the results of a 2-year investigation by the U.S. Geological Survey, in cooperation with the city of St. Petersburg, to evaluate geohydrologic conditions at a landfill in a coastal area. The report defines and describes the geologic and geohydrologic units underlying the landfill, and examines the controls these units exert on the flow and quality of surface and ground water in the area. The study increases the understanding of the geohydrologic aspects of landfill operations and will be helpful in the selection of future landfill sites in similar coastal areas.

This report provides survey information for the Biscayne Aquifer in Florida. Includes maps and tables.

This report creates flood profiles for a twenty-seven-mile stretch of Cypress Creek, Florida, and is deemed to be accurate within a standard deviation of plus-or-minus zero point five feet. It includes maps and graphs.

This map depicts the approximate top of the rock that composes the Floridan aquifer. The contours represent the elevation of the top of the Floridan aquifer to mean sea level.

This model evaluates the recently-developed well field in Cypress Creek, Florida. It includes maps and graphs.

This report examines the water quality of water within the Miami Canal, an important source of recharge for the recharge for the Biscayne aquifer. It includes maps and other figures.

"This report presents flood heights and profiles for a seventy-mile reach of Peace River from Bartow to Arcadia," Florida, "calculated using the United States Geological Survey step-backwater model." It includes maps, graphs, and tables.

This report presents an appraisal of the millions of gallons of water lost to uncontrolled flowing wells in Florida. It includes maps and tables.

"This report presents the hydraulic and chemical data collected at a deep-well waste-injection system near Pensacola, Florida." It includes maps, graphs, and tables.

From abstract: This report presents collected data on daily water use for Florida in the year 1975 and includes several maps and tables.

This report promotes the use of a large aquifer in Charlotte Count, Florida as a source of a fresh water for the region. It includes maps, graphs, and other diagrams.
