Title: Artificial neural network prediction of alluvial river geometry.
Creator: Hoffman, David Carl., Florida Atlantic University, Scarlatos, Panagiotis (Pete) D.
Abstract/Description: An artificial neural network is used to predict the stable geometry of alluvial rivers. This knowledge is useful for the design of new channels or modification of natural rivers. Given inputs of river discharge, slope and mean particle size, an artificial neural network is trained to predict the corresponding stable channel width and depth. The network is trained using data from several alluvial canals and rivers. Various factors including training set size and composition, number of hidden...
Show moreAn artificial neural network is used to predict the stable geometry of alluvial rivers. This knowledge is useful for the design of new channels or modification of natural rivers. Given inputs of river discharge, slope and mean particle size, an artificial neural network is trained to predict the corresponding stable channel width and depth. The network is trained using data from several alluvial canals and rivers. Various factors including training set size and composition, number of hidden layer nodes, activation function type, and data scaling method are analyzed as variables affecting network performance. These factors are studied to determine impacts on network accuracy and generalizing ability.

Show moreThe purpose of this study was to develop a user-friendly mathematical model for prediction of daily, ground level ozone concentration in Palm Beach County, Florida. The focus of this project was to investigate the correlation between hourly ozone concentrations and pre-existing pollutant levels and meteorological data. An artificial neural network model was applied, involving a backpropagation algorithm and the tangent sigmoid as the transfer function. Surface meteorological data and upper air data such as pressure, temperature, dew point temperature, wind speed and wind direction were included in the model, along with the ozone concentration in the hour previous to the forecast. Based on the model results, the 8-hour average ozone concentration is to be forecasted. This will assist state and local air pollution officials in providing the general public with early notice of an impending air quality problem.

Show moreDrainage waters leaving the Everglades Agricultural Area (EAA) have been implicated as having adverse effects on the receiving Water Conservation Areas (WCAs) and Everglades National Park (ENP). The objectives were to quantify and describe the rainfall and drainage events, characterize their effects on the water table system, and determine any relationships between the open channel drainage system and the field water tables on farms in the EAA. Water table rise in the soil profile from rainfall averaged a ratio of 10.6:1. Traditional expectations of field drainage behavior to channel gradients were not apparent. Field observation well drainage rates showed no direct relationships to distances across the farm or to the main station pumping rate. Due to the similar field water table responses under varying drainage scenarios, the organic soil, open channels, and the underlying geology were determined to function as an integrated system with respect to the movement of water.

Title: The laboratory measurement of soluble phosphorus diffusion coefficients in kaolinite and bentonite clay sediments.
Creator: Donovan, William Cullen., Florida Atlantic University, Scarlatos, Panagiotis (Pete) D.
Abstract/Description: The specific effects of sediment resuspension on the rate and amount of phosphorus diffusion by commercially available kaolinite and bentonite soils were examined in a laboratory setting by amending the soils with phosphorus fertilizer (46% P2O5), reacting them in a plexiglass container (by removing a partition) and allowing the soils to mix with the overlying water column as they spread along the container bottom.

Show moreThe specific effects of sediment resuspension on the rate and amount of phosphorus diffusion by commercially available kaolinite and bentonite soils were examined in a laboratory setting by amending the soils with phosphorus fertilizer (46% P2O5), reacting them in a plexiglass container (by removing a partition) and allowing the soils to mix with the overlying water column as they spread along the container bottom. The concentration of total phosphorus was measured at 1, 3, 6, 12, 24 and 36 hours after reaction occurred. A computer program was written to calculate the diffusion coefficients (D) for the different soil and fertilizer treatments. Correcting the D values for adsorption resulted in effective diffusion coefficients (De) values, averaged across all retardation factors, of 0.010; 0.0017 and 0.0124 cm^2/day for the 13,944; 9,295 and 4,648 mu g/1 phosphorus fertilizer kaolinite treatments and 0.0002; 0.0006 and 0.0013 cm^2/day for the 13,654; 9,103 and 4,552 mu g/1 phosphorus fertilizer bentonite treatments. The diffusion coefficients for the kaolinite soil treatments were consistently greater than those for the bentonite treatments.

Title: Ecological impact of arsenic, chromium and lead from application of recovered screened material on Florida soils.
Creator: Scarlatos, Dimitrios., Florida Atlantic University, Scarlatos, Panagiotis (Pete) D., College of Engineering and Computer Science, Department of Ocean and Mechanical Engineering
Abstract/Description: Disposal of construction and demolition (C&D) debris is a major problem. During recycling operations, the debris is passed over screens, generating what is called Recovered Screened Material (RSM). Previous analyses of RSM indicated high arsenic (As) levels. Thus, RSM is disposed in landfills in spite of the fact that natural soils may contain As levels higher than the proposed concentrations for soil clean-up goals.

During recycling operations, the debris is passed over screens, generating what is called Recovered Screened Material (RSM). Previous analyses of RSM indicated high arsenic (As) levels. Thus, RSM is disposed in landfills in spite of the fact that natural soils may contain As levels higher than the proposed concentrations for soil clean-up goals. RSM samples were collected and analyzed from seven C&D debris recycling facilities and from other sites. The average arsenic content found in RSM ranged between residential and industrial clean-up goals. Chromium and lead levels in RSM were very low. The RSM quality depends mainly on the waste stream. Recycling procedures do not have any major effect on the RSM. Arsenic levels in natural soils showed a wide variability. Almost half of the soil samples had an arsenic level comparable to that found in RSM.

Subsystems were used to define the Levels of Standards (LOS) for the drainage system of the village. The data was collected from different sources such as Palm Beach County, or the property appraisers. The features are linked to databases, where the user can interface with the system and analyze the storm water network of the village. In the end, an interactive map was created with all the data, which provided a sufficient management tool for the Utilities Department.

Concerning the toxic volatile organic compounds, the simulations indicate that benzene exceeded the previous permissible air quality standard. Toluene, ethylbenzene and xylene values remained within allowable concentration levels. Long-term annual benzene emissions from stationary sources exceeded the former reference concentration of 0.12 mug/m 3 about five times per year, whereas the data for 8 and 24 hours were relatively low. Simulation results for the mobile sources demonstrated that the emission factor is a highly sensitive parameter. Possible realistic scenarios at Port Everglades were obtained through varying benzene concentrations. The results are plotted as concentration contours, in order to visualize areas of suspected health risk associated to air pollution. Compared to the Reference Concentration for Chronic Inhalation Exposure, EPA, the modeled results appear significantly less.

The purpose of this thesis is to develop analytical solutions of the unsteady advection-dispersion equation as applied to free surface closed-end canals. Solutions are obtained under various initial and boundary conditions, by using the finite transformation analysis. The simulation results are validated against laboratory data.

Show moreA complete understanding of nitrate partitioning between water and sediments is absolutely necessary to quantify eutrophication and other harmful effects of nitrate addition to a lake. The bottom sediments can act both as source and sink for nitrates. Turbulent conditions induced by wind forces cause sediments to suspend in the water column. During suspension sediments adsorb/release nitrates and other contaminants into the ambient water. This study investigated the effects of temperature, sediment and nitrate concentration on the exchange and partitioning of nitrates between water and sediments. The Langmuir adsorption model was used to quantify the adsorption/desorption processes. A decrease in the value of partition coefficient with increase in sediment concentration was observed. The laboratory experiments revealed that an increase in temperature of the water column favored the adsorption of nitrates by the bottom sediments. The nitrate diffusion coefficients were estimated by utilizing Fick's second law of diffusion. Sediment concentration profiles were strongly dependant on the oscillating-grid induced turbulence effects.

The sediment suspension was found to have a significant effect on phosphorus movement to the upper layer water. Higher temperature increased the release of phosphorus from kaolinite and lake sediments, and the effect was almost nil for bentonite. Temperature effect was pronounced on kaolinite where relatively higher release of phosphorus observed. Salinity effect on lake sediments was not significantly important for release or adsorption. Bentonite showed a release of phosphorus after addition of salts. Adsorption on kaolinite was found higher at pH 4.7-5.0. The study was also focused on the estimation of phosphorus partitioning due to molecular diffusion and turbulent mixing. The observed behavior of the phosphorus exchange under different conditions showed an agreement with the observations by the other investigators.

A specially written computer program combines inlet/nearshore hydrodynamic expressions with bed-load and suspended load sediment transport relationships to examine the building mechanisms of the near-shore tidal ebb shoal. The ebb tidal flow is modeled as a turbulent, plane jet which includes lateral mixing and entrainment, bottom friction, and offshore bathymetric changes. Flood tidal flow is modeled as a potential flow sink with the water being drawn into the inlet from one or more dominant offshore areas depending on the offshore bottom slope. Sediment transport expressions are evaluated at various locations within the offshore flow field and the sediment deposition depth is calculated at that location over one tidal cycle. Model results are plotted and compared to field data for analysis.

By field testing, and comparing the recorded data with the theoretical GPS data, it was seen that non-DGPS could be rather accurate. Furthermore, it can be justified for a GPS unit to eliminate the Z coordinate measurement since vertical position errors are larger than horizontal errors, which may lead to improved accuracy. On the other hand, some 'visibility problems' were encountered while testing the GPS units under driving conditions. Different ways to compensate for this disadvantage were studied. In the end, the different features of the GPS unit were discussed and a way to improve the system was also proposed.

Show moreThis study pertaining to the settling of fine particles is developed using various models and formulas. The model considers two layers, i.e, the suspension zone dominated by perikinetic flocculation and the settling zone governed by gravitational force. In the suspension zone, floc formation of fine particles is simulated by the maximum chain model in which floc parameters and fractal dimension are compared with existing data. In addition, fractal dimension is compared with that of the hierarchical model. The main assumption of the model is that any floc having sixteen particles outweighs Brownian force, and thus the floc starts falling down into the settling zone. The flocs moving from the suspension zone are considered as nonspherical particles in the settling zone. The study uses a dimensionless settling velocity, omega*, for estimation of the sedimentation of flocs. Settling causes aggregation of the depositing flocs. The form of these aggregates is analyzed by the fractal relationship P ~ L delta.

Show moreModem technology has led to a new generation of landfill liner systems that are highly efficient at intercepting and removing leachate. Many of the modem liner systems are so effective that little or no leakage occurs through the liner systems. What leakage may occur is so minimal that, although it can be theoretically predicted, it cannot be measured, i.e., the resulting groundwater concentrations are well beneath minimum detection levels of available monitoring well technology. In addition to being highly effective, some modem liner systems are constructed with two liners separated by a drainage medium which detects and removes any leakage through the top liner. These significant improvements in liner system technology have led many landfill designers, operators, and regulators to question the necessity for current monitoring well practices. Currently, landfills are required to have a large number of monitoring wells, and the associated large installation, sampling, and testing costs are inevitably reflected in higher tipping fees or higher taxes. In either case, the costs are borne by the public. If the number and frequency of sampling of monitoring wells could be reduced, significant cost savings could be realized, and the money saved could perhaps be better spent elsewhere. This thesis reports the results of research conducted at eleven landfills constructed with modem landfill liner systems to determine the actual and probable efficacy of the role o: monitoring wells, and conducts a cost-saving analysis to evaluate whether funds would have been better spent elsewhere.
