Civil Engineering

Civil engineering faculty are actively engaged in a wide range of research areas including construction management, geotechnical engineering, materials, structures, transportation and water resources. Geotechnical research pertains to in situ testing of soils, fiber-optic sensors in soils and evaluation of pavements. Research in materials is being conducted in the areas of concrete materials at a fundamental level using nanotechnology to characterize their mechanical properties, fiber-reinforced concrete and nondestructive testing technologies, and stabilization of waste materials for beneficial uses. Structural engineering research is in the areas of wind and seismic engineering, control of vibrations, catastrophe risk modeling and wireless instrumentation development. Transportation research combines mathematical programing, network science and behavioral modeling to develop new transportation paradigms. Research activities include integration of novel truck datasets and analytics into enhanced models, development of business strategies for sustainable transportation, resilience in global interdependent systems and technological opportunities for freight transportation. Water resources research includes numerical groundwater modeling, design and performance of stormwater management systems, and physical modeling of unstable saltwater systems in groundwater.

Laboratories for research and instructional activities are available in the areas of materials and structures and soil mechanics. The materials and structures laboratory is equipped with several universal testing machines for physical testing, and equipment and instrumentation for experimental stress analysis. The soil mechanics laboratory contains commercial equipment for evaluating the engineering properties of soils.

Faculty research has been supported through several grants from the federal agencies such as the National Science Foundation, National Research Council of Canada, Florida Department of Energy, Florida Department of Transportation, Florida Department of Energy Management, Florida Department of Community Affairs/FEMA etc.

Environmental and Water Resources Engineering

Pandit and Dr. Heck have worked together in several projects. While Dr. Pandit is an expert modeler, Dr. Heck’s expertise lies in laboratory and field data collection. Dr. Pandit has developed two finite-element ground water models, GROSEEP (Groundwater Seepage) and SOLTRA (Solute Transport), and two non-point source models CALSIM (Continuous Annual Load Simulation Model) and WEANES (Wet Pond Annual Efficiency Simulation). The research areas of interest of the faculty members in the Water Resources/Environmental Engineering area are listed below.

Numerical modeling of contaminant transport in subsurface media: We have recently conducted field, laboratory and numerical experiments to estimate the transport of groundwater seepages and nutrient loadings into a coastal estuary known as the Indian River lagoon from the adjacent watershed. Two of the numerical models used for this study are MODFLOW and SEAWAT. This research is part of a more comprehensive effort to determine nutrient loads into the Indian River Lagoon from various sources such as surface water flowing through canals, septic tanks and “muck”. Links to our recent publications and presentations are provided below: (Links 1 to 4)

Unstable flows using physical models: There are many real-world situations where a mass of relatively heavier fluid overlies a porous media containing a lighter fluid. For example, this is fairly common at landfills and waste dump sites, saline disposal basins, seawater inundation along coastal aquifers, and in estuaries. We have conducted laboratory and numerical experiments to study the transport mechanisms of overlying, heavier saltwater into underlying freshwater under various conditions. Links to a presentation we recently made is provided below. (Link 5)

Stormwater management: Our main areas of interest in Stormwater Management are in predicting non-point source nutrient loads from watersheds and in understanding the removal efficiencies of best management practices used to remove pollutants generated by non-point sources. Links to our publications are provided below. (Link 6)
