Effects of Recharge from Drainage Wells on Quality of Water in the Floridan Aquifer in the Orlando Area, Central Florida

Description: From purpose and content: The purpose of this report is to: (1) describe the general quality of ground water found in the injection zones (permeable strata that accept water) of drainage wells; (2) assess the impact of drainage wells on the water quality of supply wells, particularly public-supply; and (3) establish a data base necessary for future studies.

Hydrologic Relations Between Lakes and Aquifers in a Recharge Area near Orlando, Florida

Description: Abstract: The three lakes investigated gain water- from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents hydraulic gradient between lake and water-table aquifer, A is lumped parameter representing effect of hydaulic conductivity and cross-sectional area of materials in flow section of water-table aquifer, Y is head difference between lake level and potentiometric surface of Floridan aquifer, and B is lumped parameter representing effect of hydraulic conductivity, area, and thickness of materials between lake bottom and Floridan aquifer. If values of S, X, and Y are available for two contrasting water-level conditions, coefficients A and B are determinable by solution of two simultaneous equations. If the relation between lake- and ground-water level is same on all sides of the lake with regard to each aquifer and if X and Y are truly representative of these relations, then X and Y terms of equation provide valid estimates of inflow to lake from water-table aquifer and outflow from lake to Floridan aquifer.

Orlando Area (ARMS-II)

Description: From Abstract: "The data are presented as aeroradioactivity units or areas with similar gamma radiation counting rates at 500 ft., at two map scales: (1) generalized at about 1: 1,000,000 and (2) detailed at 1:250,000. The maximum aeroradioactivity in almost all the area was less than 400 counts/sec. Aerial measurements of ground radioactivity in the ARMS-II Orlando area were consistent with what was expected, considering the geology of the area."

An analysis of the variation with altitude of effective gust velocity in convective-type clouds

Description: From Introduction: "In the present paper, the variation of effective gust velocity in convective-type clouds with altitude is investigated. Data obtained during 1941 and 1942 at altitudes up to 34,000 feet and data obtained more recently from the Thunderstorm Project (reference 5) at altitudes up to 26,000 feet are utilized for this purpose. Consideration is given in analyzing the results both to data for the range
