Artificial recharge to the Floridan aquifer system, Orlando Area, Central Florida
Approximately 400 drainage wells exist in Orange County, central Florida. The rate of recharge through drainage wells is limited by the rate of surface flow to the wells; the hydraulic properties of weirs, overflow pipes, and well casings; or the water level above the top of the casing. The rate commonly is not limited by the hydraulic properties of the very transmissive aquifer system.

Assessment of geothermal resources at Newcastle, Utah
Integrated geology, geophysics, and geochemistry studies in the Newcastle area of southwest Utah are used to develop a conceptual geologic model of a blind, moderate-temperature hydrothermal system. Studies using 12 existing and 12 new, thermal gradient test holes, in addition to geologic mapping, gravity surveys, and other investigations have helped define the thermal regime. Preliminary results

Changes along a seawall and natural beaches: Fourchon, LA
This paper compares shoreline and beach morphology changes and responses to storms from 1985 to 1988 along sections of a rapidly eroding coast at the Bayou Lafourche headland, Louisiana. A beach consisting of a cement-filled bag seawall and nourishment was compared with natural beaches to the west and east of the project. Local patterns of beach response could be attributed to several recent proce

Comparative facies formation in selected coal beds of the Powder River Basin
Petrologic studies of thick coal beds [Warwick, 1985; Moore, 1986; Moore and others, 1986; Moore and others, 1987; Warwick and Stanton, in press], which build on sedimentological interpretations [Flores, this volume] of associated units, provide data to interpret and contrast the varieties of peat formation in the Powder River Basin. Detailed analyses of the composition of coal beds lead to more c

Comparison of early exploration at Platanares (Honduras) and Wairakei (New Zealand)
Early exploration at Wairakei, New Zealand, is compared with the present state of exploration of Platanares, Honduras. In retrospect, geothermometer temperatures favor Platanares (e.g., 220 vs. 190??C for Na-K-Ca), but two 600-m drill holes encountered lower temperatures (160??C). Wairakei, explored before the advent of chemical geothermometry, also had disappointing early drilling results (but be
