Title: Variations in model discretization methodology and its effects upon groundwater modeling.
Creator: Whitman, Jason L., Florida Atlantic University, Restrepo, Jorge I.
Abstract/Description: It is a fundamental supposition in groundwater modeling that as the discretization of a model domain is increased, the model's precision increases accordingly (Anderson and Woessner, 1992). However, the quantifiable amount and specific circumstances of that benefit remain unclear. The purpose of this research is to examine the output variations discerned as a result of applying successively coarsened discretization scenarios to a groundwater model test case.

Show moreIt is a fundamental supposition in groundwater modeling that as the discretization of a model domain is increased, the model's precision increases accordingly (Anderson and Woessner, 1992). However, the quantifiable amount and specific circumstances of that benefit remain unclear. The purpose of this research is to examine the output variations discerned as a result of applying successively coarsened discretization scenarios to a groundwater model test case. The test models, comprised of both regular (square) and irregular forty-four individual model output solutions. Detailed analysis of the piezometric head values, mass balance flow terms, and solution convergence times for each model run provides valuable insight into the complex relationship existing between spatial discretization and its effect upon model output values. Consequently, the aforementioned relationship proves to be highly complex, often affecting multiple model parameters in dissimilar manners while maintaining consistency in others.

Show moreDeep injection wells (DIW) in Florida are regulated by the U.S. Environmental Protection Agency (USEPA) and the state of Florida through the Underground Injection Control regulations contained within the Safe Drinking Water Act. Underground injection is defined as the injection of hazardous waste, nonhazardous waste, or municipal waste below the lowermost formation containing an underground source of drinking water within one-quarter mile of the wellbore. Municipalities in Florida have been using underground injection as an alternative to surface disposal of treated domestic wastewater for nearly 40 years. The research involved collecting data as of September, 2007 on all the Class I DIWs in the state of Florida and evaluating the differences between them. The analysis found regional differences in deep well practice and canonical correlation analyses concluded that depth below the USDW is the most significant factor to prevent upward migration of the injected fluid.

Show moreThe objective is to develop a groundwater flow model of the Surficial Aquifer System in the area of Plantation, Broward County, Florida, using the U.S. Geological Survey MODFLOW code and to make a comparison between the use of two supplementary contaminant transport models: MODPATH code and the MT3D code. The advantages and limitations of the two solute transport models are described and an evaluation is made of their accuracy with respect to delineation of traveltime related to capture zones of wells. Final results of the computer simulations indicate that this study area is sensitive to river bed hydraulic conductivity and the stress of the continuous pumping at a nearby wellfield. Therefore, a critical factor in selecting an appropriate flow model for delineating the traveltime-related capture zone of a well is a model which simplifies the flow system while still preserving hydrogeologic characteristics of the flow system.

Show moreGroundwater is a valuable resource essential for residential, agricultural, commercial, and environmental water supply needs in Florida. Understanding drivers of groundwater level trends and time series forecasting in vulnerable areas provides water managers with timely information for effective resource protection. This study evaluates groundwater level trends in the surficial, intermediate and Floridan aquifer systems in Central and South Florida at 106 unconfined and confined aquifer wells using 15 to 27 years of data through 2019. Wells were clustered into relatively homogenous groups based on spatial characteristics using the k mean clustering method. Land surface and top of aquifer elevations as well as groundwater level ranges were key factors. Distance to the coast was also important for surficial aquifer clustering, while proximity to water supply wells influenced Mid-Hawthorn aquifer (MHA) results. Principal component analyses (PCAs) were performed using rainfall, temperature, actual evapotranspiration, El Niño Southern Oscillation, and population data and regressed against average monthly groundwater levels for each cluster. This study is the first of its kind PCA using variables impacting groundwater levels in South Florida. Sandstone aquifer PCAs correlated well with groundwater levels. When compared with multiple linear regression, PCA results had similar correlation. However, the drivers of groundwater level trends identified by each method for the MHA and Upper Floridan aquifer (UFA) differed. Seasonal Kendall trend tests indicated 12 surficial aquifer wells had trends related to changes in land use and decreased usage. MHA trends were related to exploitation or a shift in water source usage. A regional increasing trend exists in the UFA in South Florida.

Show moreDeep injection well technology is a reliable and cost-effective technique to manage hazardous wastewater. However, reduced injectivity is an issue for the performance of an injection well which can happen due to the occurrence of biogeochemical clogging. A class 1 deep injection well located at the Solid Waste Authority of Palm Beach County has long suffered similar problems that occurred due to the formation of chemical precipitation and biofilm. In the case of the biofilm, the dominant microorganism detected in previous work was determined to be Entamoeba dispar. The prime source of the protozoan was identified as the local groundwater, which is employed for different purposes within the solid waste facility, such as cooling water and dilution water. Therefore, it is imperative to examine the effectiveness of the commonly used disinfectant chlorine to inactivate the protozoan to eliminate biofilms and clogging. This study conducted a laboratory-based chlorination of the groundwater sample to reveal the required dosages of chlorine needed for 3.0-log inactivation of E. dispar in various temperature (20°C, 25°C, 30°C, and 35°C) and pH (6.5, 7.0, 7.5) conditions.

Title: Infrastructure to model complex systems: hydrological modeling.
Creator: Wissinger, Frank, Shankar, Ravi, Florida Atlantic University, College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description: This research proposes an Infrastructure to model complex systems for hydrological modeling. Currently, the three main hydrological packages are: i) SEAWAT (modeling groundwater flow); ii) HECRAS (modeling surface water flow); iii) HEC-HMS (modeling atmospheric water flow). Each of these models is self-contained and has a different timescale and simulation speed. Consequently, any integrated model will only run as fast as the slowest of the models.

Show moreThis research proposes an Infrastructure to model complex systems for hydrological modeling. Currently, the three main hydrological packages are: i) SEAWAT (modeling groundwater flow); ii) HECRAS (modeling surface water flow); iii) HEC-HMS (modeling atmospheric water flow). Each of these models is self-contained and has a different timescale and simulation speed. Consequently, any integrated model will only run as fast as the slowest of the models. This makes it difficult to provide reliable and dynamic information on water levels and water availability for a given geographical region in a timely manner. The goal of this research is to facilitate the integration of multiple hydrological models from different hydrological packages by applying Electronic Design Automation (EDA) methodologies, including System Level Design (SLD) methodology, SystemC-AMS language, Python language and libraries (numpy, Statsmodels, and ctypes). The EDA methodology brings in the additional advantage of significantly improved simulation speed. The Infrastructure to Model Complex Systems applications is demonstrated using the following SEAWAT benchmark problems: i) Case 1; ii) Henry; iii) Elder problem. Simulation results from the aforementioned benchmarks are analyzed and discussed. Lastly, future research work is presented.

The objective of this study is to obtain analytical solutions for the backward type Kolmogorov equations governing certain crucial variables in the case of a two-dimensional medium. These include the rate at which pollutants enter the protected zone and the length of time that a pollutant particle takes to travel from a given location to the boundary of the protected zone. It is assumed that the groundwater flow is horizontal and uniform, and that a protected zone is located downstream. Analytical solutions are obtained by using the techniques of Laplace transform and separation of variables. Numerical results are given for two cases, one with flow coming from a boundary which is imperious to the pollutant, and another with flow coming from infinity.

Show moreThe problem of solute transport through saturated porous media is considered in this thesis. The end application of this study is to evaluate the option of spray irrigation as a means of disposing reverse osmosis effluent. Reverse osmosis effluent was sprayed on an experimental field composed of typical area soil. The changes in groundwater quality were monitored at intervals of ten to twenty days. Applying the experimentally obtained data to a basic numerical model, which uses the convection-diffusion equation, the key parameter of the soil, D* the diffusion coefficient, is obtained for the Myakka sand. While the numerical model can predict the qualitative behavior of hardness and conductivity, hysteresis is observed for the response of the total organic carbon (TOC) content. Further studies are needed to understand and model the inherent capacitance of the soil for hardness and the observed hysteresis in TOC response.

Since 1952, much of the wetland habitat has succeeded to terrestrial pine flatwoods in the southwestern section of the wilderness preserve of JDSP. The drying trend can not be linked to natural hydrologic impact, but strongly correlates to groundwater drawdown calculated using a three-dimensional groundwater computer model.

Show moreHuman exposure to arsenic from natural as well as anthropogenic sources can lead to a detrimental impact to the nervous system, cardiovascular system and can also cause cancer. Historical agricultural runoff has led to an accumulation of arsenic in groundwater and soils around Lake Okeechobee and many golf courses in Florida. This research involved studying the removal of aqueous arsenic via adsorption using activated carbon derived from algae. Carbon derived from Sargassum removed 41.47% of arsenic after a contact time of 2 hours. Adsorbents created from blue-green algae showed essentially no arsenic removal under the same conditions. Various chemical additives were tested to improve arsenic adsorption as well. Modification of the adsorbent surface with magnesium chloride demonstrated an arsenic removal efficiency of 98.6% when added to commercial activated carbon. However, when magnesium chloride was used to modify the surface of Sargassum-derived carbon adsorbents, the arsenic removal efficiency after 2 hours was 26.7%. It is recommended to investigate other surface modification agents that can potentially improve adsorption of arsenic.

Show moreBarometric distillation is an alternative method of producing fresh water by desalination. This proposed process evaporates saline water at low pressure and consequently low temperature; low pressure conditions are achieved by use of barometric columns and condensation is by direct contact with a supply of fresh water that will be augmented by the distillate. Low-temperature sources of heat, such as the cooling water rejected by electrical power generating facilities, can supply this system with the latent heat of evaporation. Experiments are presented that show successful distillation with a temperature difference between evaporator and condenser smaller than 10ê C. Accumulation of dissolved gases coming out of solution, a classic problem in lowpressure distillation, is indirectly measured using a gas-tension sensor. The results of these experiments are used in an analysis of the specific energy required by a production process capable of producing 15 liters per hour. With a 20ê C difference, and neglecting latent heat, this analysis yields a specific energy of 1.85 kilowatt-hour per cubic meter, consumed by water pumping and by removal of non-condensable gases.

Show moreArsenic is a known carcinogen, but is persistent in the environment, remaining a popular pesticide. It represents a particular hazard to humans when it stays resident in shallow soils and groundwater. This study of contaminant hydrogeology examined conditions at a former golf course in Florida with known arsenic contamination, and included a detailed examination of existing assessment data for the study area, an experimental pumping test with groundwater sampling, examination of sediment cores, and a preliminary geophysical investigation. The primary purpose was to determine what the existing controls are on As mobility. The primary findings were that redox conditions did have an effect on As concentrations. Groundwater in the study area is generally reducing, but during the pumping test was generally oxidizing. No potential As sources were definitively identified, and the most likely source remains anthropogenic, but interactive conditions with Fe, Mn, NO3-N, and S remain nebulous.
