C. Dan Miller, R. Sushyar, Santoso, S. Hamidi
1983, Open-File Report 83-68
The Dieng Mountains region consists of a complex of late Quaternary to recent volcanic stratocones, parasitic vents, and explosion craters. Six age groups of volcanic centers, eruptive products, and explosion craters are recognized in the region based on their morphology, degree of dissection, stratigraphic relationships, and degree of weathering. These...

Effects of recharge from drainage wells on quality of water in the Floridan Aquifer in the Orlando area, central Florida
G. R. Schiner, E. R. German
1983, Water-Resources Investigations Report 82-4094
Approximately 400 drainage wells in the Orlando area inject, by gravity, large quantities of stormwater runoff that may or may not be suitable for most purposes without treatment into the same freshwater zones of the Floridan aquifer tapped for public supply. The wells are used mostly to control lake levels...
Effects of ground-water development in the North Fort Hood area, Coryell County, Texas
