The Development Of A Hydrodynamics-Based Storm Severity Index, Gabriel Francis Todaro

UNF Graduate Theses and Dissertations

A hydrodynamic-based storm severity scale that ranks the damage potential of a storm at a given coastal area is developed. Seventeen tropical and extratropical storm events at 113 different locations on the Atlantic coast and the Gulf of Mexico are examined in order to create and verify a Storm Severity Index Model (SSIM). The results from the SSIM are then used to create a location-based storm severity scale titled the Twenty-Four Point Storm Severity Scale. The Twenty-Four Point Scale is based on three subsets of factors. The first is the energy flux above the normal mean high water line that …

Examining Optimal Form Of Two Scale Approximation (Tsa) For Calculating Snl Source Term, Dorukhan Ardag

UNF Graduate Theses and Dissertations

Nonlinear four-wave interactions (S_nl) are critical for acquiring realistic spectra needed by operational wave models. High computational demand to calculate these interactions led to an approximation method named the Discrete Interaction Approximation (DIA) to be used broadly in the major operational wave models for a long time. However, the accuracy of the DIA has been controversial since it was first introduced and more precise approximations such as the Two Scale Approximation (TSA in short) are now available. The only issue with the initial TSA`s efficiency is performing an order of a magnitude slower than the DIA in speed. …

Factors Affecting Storm Characteristics In The Battery And Vicinity, Shannon A. Kay

UNF Graduate Theses and Dissertations

Tropical cyclones (TCs) Irene and Sandy caused major damages in back to back years to the most densely populated city in the United States stunning the residents with storms linked to seemingly impossible probabilities. Such activity has raised questions about the effect of non-stationary aspects within atmospheric circulation on storm behavior and some assumptions inherent in previous hazard studies of the New York City (NYC) area. This study analyzes statistical aspects of hazard quantification for this area related to this non-stationarity and statistical characterization. In particular this study investigates the presence of multiple populations of storms, it also tests current …

Analysis Of A 10-Year Nearshore Wave Database And Its Implications To Littoral Processes, Luis Humberto Montoya

UNF Graduate Theses and Dissertations

The variability of the nearshore wave climate is investigated via the analysis of over 10 years of Acoustic Doppler Current Profiler (ADCP) data from a gauge deployed at Melbourne Beach, FL. Examples of large yearly variability in the significant wave height, peak period, mean direction and energy distribution are found in the data. Estimates of the averaged spectra for the entire record show that the average wave energy is distributed almost symmetrically with the peak being close to shore-normal. It was expected that the peak would be shifted towards the north of shore-normal considering net north to south longshore sediment …

This study included analysis of 15 bridge models that met the FDOT standards. The main beams were designed and load rated using commercial software to obtain live load deflections. The bridges were checked to verify that …

The Effects Of Rain On Traffic Safety And Operations On Florida Freeways, Michelle L. Angel

UNF Graduate Theses and Dissertations

Although the association between weather and traffic variables or crash events appear intuitive to motorists, quantifying the effects that weather, especially rain, has on driver response in travel speeds, traffic demands, and susceptibility of accident occurrence is needed to evaluate practical aspects of traffic operations and safety measures. Previous studies have researched driver responses to inclement weather on roadways located primarily in northern and western regions of the United States (U.S.), Canada, and Europe. However, driver familiarity to local weather conditions is a factor that should be considered in determining inclement weather effects on traffic variables and crash occurrence. This …

Investigation Into The Relationship Between Hurricane Storm Parameters And Damage, Jeremy S. Young

UNF Graduate Theses and Dissertations

“Economic damage, such as damage to property and infra-structure, from hurricane surges depends on two factors 1) the depth of coastal inundation and 2) the area covered by the surge” (Irish et. al 2007). Typically, damage estimates are developed after hurricanes have dissipated. To have the ability to predict hurricane damage in advance based upon various physical parameters would be a technical advance that could aid vulnerable coastal communities with hurricane planning. This thesis advances this goal forward by relating “Total Normalized Damage” to “Surge Scale” along with other key parameters. In this thesis Total Normalized Damages are compared to …

Disinfection Performance Of Peracetic Acid In Florida Wastewater Reuse Applications, Killian Eckert

UNF Graduate Theses and Dissertations

As Florida’s population continues to grow and urbanization increases, traditional freshwater sources are in danger of being exhausted. Wastewater reuse programs offer a way to create a potable offset in order to protect these freshwater sources and the environments in which they are found. Reuse regulations for the disinfection of wastewater are increasingly becoming more stringent. In addition to tough regulations, operating costs have also become a driving force behind a movement to assess new and potentially economical chemicals and processes for disinfection. The objective of this thesis is to assess the disinfection performance of peracetic acid (PAA), an alternative …

Corrosion Of Post-Tensioned Tendons Repaired With Dissimilar Grout, Juan Carlos Rafols

UNF Graduate Theses and Dissertations

A failure associated with steel corrosion was identified in early 2011 in a bridge external post-tensioned tendon, approximately eight years after construction. Large voids in the grout and pockets of non-homogeneous material were identified. The non-homogeneous grout was characterized by high moisture content, and in most cases, the chloride content was lower than conservative threshold values. The non-homogeneous grout also had high pH and high content of sulfates (approximately in the range of 10,000-ppm). As a result, there was an interest in the study of possible corrosion development in repaired systems in which the affected tendons have been re-grouted with …

Bridge Deck Cracking Investigation And Repair, Vidal Velez Vargas

UNF Graduate Theses and Dissertations

The focus of this study is to investigate the cracking of concrete bridge decks and the sealants used in repairing transverse cracks. Cracking could occur in both hardened mature concrete and early age concrete. Several factors affect concrete cracking, such as age-dependent material properties, thermal- and moisture-related stresses and strains, material viscoelastic behavior, restraints, concrete expansion and contraction, casting sequence, formwork, material characteristics, and environmental exposure. The causes of early age cracking are primarily attributed to effects such as plastic shrinkage, temperature effects, autogenous shrinkage, and drying shrinkage. This deck cracking could greatly reduce durability, lead to a loss of …

The Repair Of Laterally Damaged Concrete Bridge Girders Using Carbon Fiber Reinforcing Polymers (Cfrp), Matthew Kent Graeff

UNF Graduate Theses and Dissertations

In recent years the use of carbon fiber reinforcing polymers (CFRP) to repair damaged structural components has become more accepted and practiced. However, the current reference for designing FRP systems to repair and strengthen reinforced concrete (RC) and prestressed concrete (PSC) girders has limitations. Similarly, very few resources address solutions for the debonding problem associated with CFRP laminates or the use of CFRP laminates to repair structural members with pre-existing damage. The included experimental program consists of testing both RC and PSC girders with simulated lateral damage and CFRP repairs. A total of 34 RC beams were statically tested under …

Correlations Between Index Properties And Unconfined Compressive Strength Of Weathered Ocala Limestone, Raoaa Farah

UNF Graduate Theses and Dissertations

Weathering has a negative effect on both physical and engineering properties of rock specimens and rock masses. When rock masses are weathered it is often difficult to obtain core segments that are the correct size for unconfined compressive strength testing. Thus engineers must use index testing to estimate the strength of specimens for design purposes. This thesis relates the unconfined compressive strength to index strength tests of Ocala limestone. The relationships developed include weathering states of the specimens and proximity of unconfined compressive strength specimens to index specimens.

One hundred and ninety five specimens were classified using International Society for …
