Wave Transformation Effects in the Vicinity of an Airport Expansion and Proposed Outfall, Doha, Qatar, Metcalf & Eddy – Coastal Engineer/Numerical Modeler.
Used USACE wave methodology to determine the effects of the expansion of the Doha International Airport upon a proposed outfall. Utilized ACES, EXTRM2 to determine the offshore wave climate under normal and storm conditions. Used the offshore wave climate to force a nearshore wave transformation model that included reflection, CGWAVE. Worked with the A&E firm to determine the proper material types to use on the airport expansion to avoid adverse impacts at the outfall.

Camp Ellis Beach/Saco River Section 111 Study, Saco, ME, United States Army Corps of Engineers - Coastal Engineer/Numerical Modeler.
Worked within a team evaluating the navigation structures at the mouth of the Saco River. Work included QA/QC of wave ADCP data collected during a two-month deployment period in the Saco region. Implementation of a wave generation model (WAVAD) that used gridded wind fields from satellites as input to obtain directional wave information as input in nearshore wave transformation models. The ADCP data was used to calibrate and verify the results of nearshore wave transformation models (STWAVE and CGWAVE). CGWAVE was used to evaluate the wave energy reduction potential from over 20 potential engineering scenarios. Utilized results from STWAVE and CGWAVE to obtain wave-induced currents and subsequent sediment transport rates and directions for both the Saco Bay region and for the area near the structure and proposed engineering solutions. Evaluated the potential lifetime of beach nourishment to be used in concert with the final four proposed structural engineering scenarios.

Structural Evaluation of Coastal Revetment at TideWatch, New Seabury, MA, TideWatch Board of Trustees - Coastal Engineer.
Used USACE methodology to evaluate the lower portion of a rock revetment that was in disrepair. Solutions included modifying the depth of burial of the toe stones and recommending an increase in stone size for both the toe stones and the armor layer. Work has included the preparation of materials for submittal for bids and licenses.

Casino Wharf Redevelopment, Falmouth Heights, MA, J K Scanla - Project Manager /Coastal Engineer.
Managed and performed an evaluation of design changes to a coastal rock revetment. Evaluated a range of coastal storm events to determine most feasible design changes, while maintaining structural integrity. Originally proposed revetment design interfered with the constructability of the building’s footings. The revetment was redesigned to remove its impact upon the construction yet maintain a protection level similar to the original proposal.

Lighthouse Beach Dewatering System, Siasconset, MA, Siasconset Beach Preservation Fund - Numerical Modeler.
Generated shoreline transect profiles that are monitoring beach changes due to a beach dewatering system. Performed QA/QC of the volumetric change and shoreline change between quarterly surveys. Evaluated the quarterly wave history from a nearby monitoring station to determine the passage of storms within the study region.

Beach Nourishment and Inlet Stabilization at Sandwich Town Beaches, Sandwich, MA, Town of Sandwich - Coastal Engineer/Numerical Modeler.
Utilized a finite element numerical wave model to evaluate the change in wave energy impacting shorebird nesting habitat on an overwash plain due to changes in inlet orientation and structural modifications. Executed a nearshore wave transformation model (STWAVE) for use in determining the potential sediment transport in the region. Evaluated the lifetime of beach nourishment under different construction scenarios.

Flood Emergency Management Association (FEMA) Flood Insurance Restudy for the Town of Hampshire, New Hampshire - Coastal Engineer/Numerical Modeler.
Project involved updating the FEMA Flood Insurance Rate Maps (FIRM) for the Town of Hampshire by adding the effects of wave run-up to the designation of flood zone boundaries. Utilized both the FEMA Coastal Hazard Analysis Modeling Program (CHAMP) as well as US Army Corps of Engineers methodology to simulate nearshore wave transformation, wave run-up and estimates of erosion potential.
