Title: Analysis of per capita water use patterns among communities with varying degrees of commercial activity.
Creator: Eustice, Robert J., Bloetscher, Frederick, Florida Atlantic University, College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: Water supply managers often look for easily applied metrics to determine where water use can be curtailed. Unfortunately, the one-size-fits-all mentality comes with a price of failing to fully grasp the consequences decision-making based on such metrics. One issue that water supply regulator like to use is per capita water use. Per capital water use is often used to show where there is “wasted” water use, such as excessive irrigation. However such a metric may not be truly applicable...
Show moreWater supply managers often look for easily applied metrics to determine where water use can be curtailed. Unfortunately, the one-size-fits-all mentality comes with a price of failing to fully grasp the consequences decision-making based on such metrics. One issue that water supply regulator like to use is per capita water use. Per capital water use is often used to show where there is “wasted” water use, such as excessive irrigation. However such a metric may not be truly applicable depending on other economic factors. A heavily industrial area may add to apparent per capital use, but actually is an economic development activity. The focus of this project is to look at various water utilities and their per capital usage with the intent of discerning whether or not a better metric could be developed that consider the economic development activities of the region and water use.

Title: THE FORMATION OF DIHALOACETONITRILES BY CHLORINATION OF NATURAL WATER.
Creator: TREHY, MICHAEL LEE., Florida Atlantic University, Bieber, Theodore I., Charles E. Schmidt College of Science, Department of Chemistry and Biochemistry
Abstract/Description: Dihaloacetonitriles (DHANs) are shown to be produced by the chlorination of natural water, thus joining the ranks of the trihalomethanes (THMs) likewise produced by chlorination. Certain amino acids such as aspartic acid, tryptophan, and tyrosine are implicated as precursor substances for the DHANs and also to some extent for the THMs. The degradation of DHANs by hydrolysis and by thiosulfate was studied. Various methods of analysis are evaluated with respect to their ability to determine...

Certain amino acids such as aspartic acid, tryptophan, and tyrosine are implicated as precursor substances for the DHANs and also to some extent for the THMs. The degradation of DHANs by hydrolysis and by thiosulfate was studied. Various methods of analysis are evaluated with respect to their ability to determine DHANs and THMs. The dilemma faced by water plants in dealing with the dual problem of DHANs and THMs is discussed. The role of hydrolysis in the formation of THMs has also been evaluated.

Show moreThis research investigates the use of rigid and flexible-membrane submerged breakwaters for wave energy attenuation. A comprehensive review of breakwater design criteria and previous research on submerged breakwaters is included. Physical model laboratory studies conducted by the author and other researchers are investigated as a means for obtaining formulations for wave transmission coefficients. The mechanisms by which waves are attenuated and break are analyzed using video photography of the wave tank tests. The primary objective of this doctoral research was to determine and compare the wave attenuation of non-conventional rigid and flexible-membrane type submerged breakwaters. Physical model tests were performed using the wave tank facilities at Florida Institute of Technology located in Melbourne, Florida. Six different breakwater cross-sections used were: (1) rectangular, (2) triangular, (3) P.E.P.-$Reef\sp{TM}$, (4) single sand-filled container, (5) three stacked sand-filled containers, and (6) one single water-filled container. The first three breakwater units were rigid (or monolithic), and the last three units are flexible-membrane breakwater units. All six units tested had the same height, length (longshore), and base width (cross-shore), with different cross-sections and shapes, and were composed of different materials. A new classification scheme was developed for breakwaters and artificial reefs, based on water depth, structure height, and wave heights. The wave-structure interaction resulting in the wave breaking on the submerged breakwaters was documented, and the observations were analyzed. Wave transmission coefficients were computed for the six different breakwater models tested, and comparisons between the different models were made. Conclusions regarding the primary factors affecting the effectiveness of rigid and flexible-membrane submerged breakwaters were developed, as were recommendations for further research.

Title: KINETICS OF N,N-DIETHYL-PARA-PHENYLENEDIAMINE WITH MONOCHLORAMINE.
Creator: GARMENDIA, MARIA J., Florida Atlantic University
Abstract/Description: The kinetics of N,N-diethyl-p-phenylenediamine with monochloramine were investigated using spectrophotometric techniques. The oxidation proceeds by two sequential steps each involving one hydrogen atom. The starting material N,N-diethyl-p-phenylenediamine and the first oxidation product are both involved in acid-base equilibria which result in a complex dependence of the reaction rate on hydrogen ion concentration. The reactions were found to follow pseudo second order kinetics, first order...

The starting material N,N-diethyl-p-phenylenediamine and the first oxidation product are both involved in acid-base equilibria which result in a complex dependence of the reaction rate on hydrogen ion concentration. The reactions were found to follow pseudo second order kinetics, first order with respect to each reactant, at a specific pH. In the presence of excess N,N-diethyl-p-phenylenediamine the formation of a dimer was observed. Mechanisms consistent with the experimental data are proposed.

Title: Beyond Water Restrictions: Informing Effective Lawn Watering Behavior.
Creator: Survis, Felicia D., Root, Tara L., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description: Evaluating trends of historical rainfall on a weekly and seasonal basis is needed for optimizing the design and implementation of lawn water conservation strategies like outdoor water restrictions. While “day of the week” water restrictions are a typical strategy to limit the frequency and duration of urban lawn water use, they may not necessarily result in more conservative behaviors from end-users. Because weekly rainfall and local climate variables are seldom taken into account in water...
Show moreEvaluating trends of historical rainfall on a weekly and seasonal basis is needed for optimizing the design and implementation of lawn water conservation strategies like outdoor water restrictions. While “day of the week” water restrictions are a typical strategy to limit the frequency and duration of urban lawn water use, they may not necessarily result in more conservative behaviors from end-users. Because weekly rainfall and local climate variables are seldom taken into account in water restriction strategies, they are not connected to actual lawn water demand. However, since lawn water demand is directly related to weekly rainfall totals, not to a particular number of watering days per week, water restriction schedules have the potential to unintentionally promote overwatering. This study investigated the weekly patterns of average seasonal rainfall and evapotranspiration in South Florida to determine the typical variability of weekly net irrigation needs and found that typical wet season weekly rainfall often provides a significant amount of water to meet the demand of residential lawns and landscapes. This finding underscores opportunity to reduce supplemental overwatering in residential landscapes if watering guidelines were modified to recognize seasonal average weekly rainfall in this region This study also tested a rainfall-based water conservation strategy to determine if providing residents with information about how local rainfall could promote more effective lawn watering behavior than just water restrictions alone. Experimental households reduced lawn water use by up to 61% compared to the control group by the end of the study. These results demonstrate that the neighborhood “rain-watered lawn” signs helped experimental study group households become more aware of rainfall as the primary input of water to their lawns. This study also investigated the role that lawn irrigation from self-supplied sources plays in the urban lawn water demand and investigates how the lawn water use and lawn watering behaviors of households that source from self-supply differ from those who source from the public supply.

Show moreA study conducted by the World Health Organization and United Nations Children's Fund, concluded that approximately 768 million people worldwide are not receiving sanitary drinking water suitable for consumption. While there are many water treatment methods, lime softening proves to be one of the more effective approaches as it removes a wide variety of harmful compounds including arsenic, lead, mercury, and cadmium under the correct conditions. The greatest issues with lime softening on a smaller scale include the complexity of the chemistry and need for monitoring. By designing the system for groundwater sources and with a smaller capacity, this thesis hoped to reduce the level of monitoring, chemical expertise, and cost needed for operation. While promising results occurred in the removal of arsenic and total hardness, this project was unable to obtain consistent results and final water samples with pH values between the recommended standard of 6.5 to 8.

Show moreThe influence of monochromatic waves interacting with a submerged bar structure is investigated through laboratory experiments in a wave flume. Wave profiles for a range of non-breaking, spilling, and plunging waves were analyzed for three offshore water depths through the interpretation of wave gauge and video imagery data. Evolution of propagating waves was reflected in data which showed increased amplitudes due to shoaling with subsequent breaking, transfer of single frequency spectrum from lower to higher frequency harmonics, and dissipation of energy after breaking onset. Comparisons of collected experimental data with previous theory developed by Yao et al (2013), Smith & Kraus (1991), Galvin (1968) for wave classification showed to be relatively accurate for both relative submergence and surf similarity methods. Wave breaking onset identified by instability in the wave crests allowed for measurements of breaking wave height and depth at breaking. Theory by Johnson (2006) and Goda (1974) compared to experimental data showed little agreement for predicting breaking wave heights.

However, the classification of data is based on land used and land cover detection. In contrast, this research is concerned with inferring WR quality from the landscape using satellite imagery and aerial photography combined with collateral data.

Show moreWater Resources (WR) agencies have recently shifted to holistic management approaches that combine the use of watersheds and ecoregions as complimentary tools. However, the classification of data is based on land used and land cover detection. In contrast, this research is concerned with inferring WR quality from the landscape using satellite imagery and aerial photography combined with collateral data. To conduct the study, three major procedures were devised: (1) construction of a classification system for regional coastal WR, (2) delineation of WR units based on the interpretation of water quality parameters (e.g. land use/cover, soil, vegetation, etc.), and (3) development and implementation of a water quality rating system. The results showed that this technique can be utilized effectively to monitor WR. The distribution of beneficial water quality was correlated with anthopogenic activities and modifications. Temporal events such as sea surface temperature had a short, but detrimental impact on water quality.

Show moreThe goal of the work described in this thesis is to design a flow augmentation device to increase the power capture and efficiency of a small-scale floating Under-Shot Water Wheel (USWW) currently being developed by Florida Atlantic University research funded by the U.S Department of Energy. The flow concentrator subsystem is intended to maximize the kinetic energy extracted by the marine hydrokinetic (MHK) energy collection device through modification of the local flow field across the capture plane. The primary objective is to increase the velocity and/or rate of mass inflow through the turbine through inserting a streamlined body in the region of interest. By utilizing the resulting flow field to increase hydraulic forcing on the waterwheel blades, the torque and/or RPM of the USWW can be increased. Based on experimental testing in the FAU wave tank at 1:5 prototype scale (280 mm wheel diameter) the flow concentrator was shown to produce an increase in device power coefficient of 17-55% measured over a velocity range of 0.16-0.45 m/s.
