Two computer models, namely MOBILE2 and PAL were utilized to estimate the air pollution emissions and concentrations due to traffic to and in the Central Florida Research Park. Since the Park is under construction, there are no actual existing data. Generally accepted engineering techniques were adopted to estimate traffic flow used for the study. Sensitivity analyses were conducted on the results, and it was found that changing the number of lanes for the roads - with different volumes of traffic on each lane - does not change the results significantly . But changing the dimensions of area sources (the parking lots in this study) did change the results. Therefore, accurate dimensions of those area sources are important to an accurate model. For areas with prevailing wind directions, long rectangular parking lots can be designed with their lengths perpendicular to the wind direction to get low pollutant concentrations. The results indicate that the carbon monoxide concentrations generated by vehicles in the Research Park will be within the Ambient Air Quality Standards for all cases studied.

This report is an examination of the practical design of a phosphoric acid production facility wet scrubber. It includes a brief background of the Florida Phosphate Industry, in addition to the rules and regulations affecting the emission of fluoride contaminates. The theoretical aspects of a packed absorption tower is discussed prior to the actual design of a cross-flow wet scrubber of the type typically found in the Florida Phosphate Industry.

Concrete block single-story detached homes are popular residences in Florida, but construction materials and methods must undergo changes to combat rising prices and material shortages. Those systems with the greatest pressure of price or material shortage will change first. When current costs and methods are examine, it is found that two systems, roof and exterior walls, have the greatest need for changes in the immediate future; and one system, thermal insulation, needs an empirical study. The roof is of materials which are in short supply and rapidly increasing in cost. The study concludes that, with present cost trends, metal frame members for the roof or a reinforced concrete slab roof are feasible alternatives. The exterior walls have excessive labor costs, and the feasible alternative may be cast-on-site masonry tilt-up panel walls. Power prices, electrical and fuel, create a need to establish new guidelines for the extent of home thermal insulation. The heat gains and losses are examined to direct future studies of the home's thermal insulation problems. The concrete block home will continue to be viable if the necessary innovations are implemented to reduce cost rate of increase and to reduce operating and maintenance costs.

Asiatic clams (Corbicula manilensis Philippi) were sampled at twelve stations randomly located along a 16-km stretch of the Wekiva River, Florida, every three months fro August 1976 to June 1977. Clams were found at most stations. Their abundance ranged from 4 to 1210 per m2. Mean numbers of Corbicula were highest at stations where the bottom sediments were primarily sand and lowest at stations where the bottom sediments were silt and decomposing organic matter. A linear relationship between water temperature, water depth, current velocity, total alkalinity, and pH, and the abundance and distribution of Corbicula was not evident. Seasonally, the abundance of Corbicula was highest in August 1976 and lowest in December 1976. The small size of the specimens suggest a recent invasion of Corbicula into the Wekiva River. The mean shell length of Corbicula in the river was 13.5 mm. The shell lengths of the largest clams ranged from 25.3 mm to 27.2 mm. Large clams were collected in December 1976 (mean shell length = 13.7 mm), whereas small clams were collected in March 1977 (mean shell length = 13.1 mm). Shell width and shell length were linearly correlated (r - 9.98 to 0.99), as were shell breadth and shell length (r = 0.96 to 0.99). The correlation between shell length and the number of rings on the shell was lower (r = 0.68 to 0.88). Clams with smaller rings (more rings per unit length) were found at downstream stations, where abundance was hing, whereas clams with larger rings (fewer rings per unit length) were found at upstream stations, where abundance was low. The data suggest that relationships between age and size depend on the habitat in which the organisms live.

The objective of this paper is to investigate the feasibility of large scale electric power generation in the state of Florida by means of solar conversion. Such systems convert solar radiation directly to electricity or to thermal energy and subsequently to electricity. With the latter method, solar energy is initially collected and converted to heat at high temperature through a working fluid. The heat is then used to power conventional heat engine generator systems. Several methods have been proposed for converting sunlight to useful work. The most promising of these will be examined from a technological and economic viewpoint.

This is a broad study of stormwater infiltration and inflow effects on two sewer systems with an equivalent size for comparison in Brevard County, Florida. The systems are Rockledge, which is located on the highest ground in the area, and Cocoa Beach, which is located down in the local water table. Rainfall data, sewage flow, quality, and flow rates were collected from the Brevard Public Health Department, Cocoa Beach and Rockledge sewage Plants, weather stations, and the Cocoa Water plant. The data indicated minimum, or no infiltration thru the Rockledge wastewater collection system. However, infiltration thru the Cocoa Beach system was estimated to be 3,800 gpd/in. dia./mi. Also, the sewage collected thru Rockledge and Cocoa Beach plants averaged about 50% and 160% of the water consumed respectively.

Stormwater management necessitates a regional plan based on the best practical methods. "Storm", a mathematical model, is employed to simulate runoff conditions in the Shingle Creek Basin. The computed runoff quantity is calibrated directly with the streams hydrograph. Runoff quality is predicted with two sets of pollutant loading rates. The scope of the model is expanded by development of parametric curves that can be used to convert measured quality data to input land use loadings. A parametric study is also performed to fabricate the effects of urbanization on the Shingle Creek Basin.
