Mr. Kelley is a Coastal Engineer at Applied Coastal Research and Engineering, Inc.  Since joining Applied Coastal, Mr. Kelley has been actively involved in a broad range of coastal engineering and analysis projects, including measurement and modeling of coastal processes.

Mr. Kelley has provided analysis input in the design of coastal engineering structures.  He has preformed overtopping risk assessments of an existing coastal dike in Matagorda Bay, TX, and also specified containment dike stone sizings and dike elevations, based an extreme hydrologic conditions, for the beneficial use of dredged sediments in the creation of wetlands in Chesapeake Bay.  Mr. Kelley has also provided design wave conditions for commuter ferry terminals at several sites on Bermuda, including an analysis of wave transmission under proposed wave baffles at one of the sites.  In addition to “hard” coastal structure design, Mr. Kelley has provided input in the design of “soft” engineering solutions, such as beach nourishments at Long Beach, Plymouth, MA; Winthrop Beach, Winthrop, MA; and Cockle Cove Beach in Chatham, MA.

Mr. Kelley has performed hydrodynamic modeling of estuaries in several towns in Massachusetts including Orleans, Bourne, Falmouth, Chatham, Barnstable, Mashpee, and Wareham.  These modeling studies were conducted as part of the Massachusetts Estuary Project, a state sponsored project (though the MDEP and University of Massachusetts) to perform comprehensive analyses to determine the relative health of 89 estuarine systems in southeastern Massachusetts.  His hydrodynamic modeling work in Falmouth, MA included water quality analyses, using the RMA4 constituent transport model to create a model for Nitrogen distribution within three coastal salt ponds.  Models were calibrated using salinity and Nitrogen data from the ponds.  The calibrated models were used to evaluate the merit of several possible scenarios of septic load reduction.  His modeling work in Chatham was part of a Town-wide water quality modeling effort that included all major estuarine systems within the Town.  As part of this project he also performed water quality modeling for an alternatives analysis for possible improvements to culverts in the Muddy Creek and Frost Fish Creek systems.

In addition to his work in Massachusetts estuaries, Mr. Kelley has performed hydrodynamic and two-dimensional sediment transport modeling analyses of Mason Inlet, North Carolina.  The modeling effort included inlet conditions that existed since completion of the inlet relocation project in 2002, as well as several possible dredging alternatives. The results of the hydrodynamics analysis for existing conditions illustrate the mechanisms likely responsible for the observed shoaling at different locations in the inlet system.  The recommended dredging alternative provided potential significant cost savings to the project, and was also the most favorable for system stability and navigation interests within the inlet system.

Mr. Kelley has conducted shoreline change studies where numerical models, including GENESIS and a shoreline model that he developed, were used to predict long-term shoreline response to incident wave processes.  For Cockle Cove in Chatham, MA, GENESIS was used together with wave model results to estimate the effectiveness and expected design life of several beach fill scenarios.  A similar implementation of GENESIS was performed for Winthrop Beach, in Winthrop, MA.  For an analysis of beach nourishment alternatives at historic Plymouth Long Beach, Mr. Kelley performed an analysis of long-term shoreline trends for selected fill designs.

Mr. Kelley also has been involved in offshore sand borrow site impact studies for sites offshore North Carolina (Outer Banks), eastern Florida, southern Virginia, northern New Jersey, and Long Island, New York.  He has used the spectral wave model STWAVE to predict changes in wave propagation along coastlines due to offshore sand mining for beach nourishment.  Wave mode results are used to compute sediment transport to provide a basis for estimating potential impacts on a shoreline.  Mr. Kelley has additional experience with other spectral wave transformation models, and has authored a report that compares the performance of spectral models, including STWAVE, SWAN, and REF/DIF s.  Mr. Kelley provided borrow site wave modeling and sediment transport potential impact analyses used in the environmental assessment of a current beach nourishment project in Virginia Beach, VA, which will use a resource area within the Minerals Management Service (MMS) jurisdiction, on Sandbridge Shoals offshore of southern Virginia.  
     In addition to numerical modeling of coastal processes, Mr. Kelley has performed measurements of inlet dynamics with the use of an Acoustic Doppler Current Profiler (ADCP).  He performed an ADCP survey of Rudee Inlet, in Virginia Beach, VA, and computed the volume of the tidal prism based on the current data.  He was involved in similar ADCP surveys for St. Lucie Inlet, FL (Martin County); Hyannis Inner Harbor, MA; the Thames River, New London, CT; and the Hudson River, NY.

Before joining Applied Coastal, Mr. Kelley was a research assistant to the head of the Ocean and Coastal Engineering division of the Civil Engineering department at Texas A&M University.  Through this work, he gained extensive experience with finite element model simulations of storm surge caused by tropical storms and hurricanes using the ADCIRC hydrodynamic software developed by the US Army Corps of Engineers.  The focus of his thesis research was the development of a storm surge forecast system based on the ADCIRC code and the Unified Planetary Boundary Layer model.  Other projects that Mr. Kelley was involved with at Texas A&M include the evaluation of revetment designs for ALCOA and BP in Lavaca Bay, TX.

Before attending Texas A&M, Mr. Kelley was employed by the Electric Boat Corporation, in Groton, Connecticut, as a member of the Advanced Concepts group.  He was responsible for the initial design of several propulsion plant and nuclear fluid systems, including component specifications and system arrangements.  He also worked with the hydromechanics analysis group, where his work included performing CFD analyses on several submarine hull and propulsion concepts.
