a remedial investigation and feasibility study assessing
<br />contaminated sediment management alternatives. Designed
<br />targeted and efficient field sampling programs and performed
<br />data analyses in support of conceptual model development.
<br />Ensured project success by conceptualizing and implementing
<br />original formulations for fine sediment transport and
<br />morphological modeling. Presented work products at
<br />conferences and to various stakeholders and published in
<br />scientific journals.
<br />Navigation Channel Deepening Impacts Assessment for Coos
<br />Bay, U.S. Army Corps of Engineers, Coos Bay, OR: Supported
<br />the development and application of coastal hydrodynamic,
<br />wave, and sediment transport/morphological models (using
<br />the Delft3D model framework) of Coos Bay. The modeling
<br />efforts were part of the environmental impact assessment
<br />associated with the proposed deepening of the existing
<br />navigation channel. The models were used to estimate future
<br />sedimentation and maintenance dredging rates, as well as the
<br />fate of dredged material placed at an offshore disposal site.
<br />Navigation Channel Sediment Management for
<br />Buenaventura Bay, Port of Buenaventura, Buenaventura,
<br />Colombia: Led the feasibility study to address sedimentation
<br />issues at the Port of Buenaventura. Responsibilities included
<br />the development of a data collection program, analysis and
<br />review of various datasets, development of conceptual site
<br />model, and development of a numerical hydrodynamic
<br />and sediment transport model (using the Delft3D model
<br />framework). The model was used to assess ongoing and future
<br />trends of sedimentation within the berths and navigation
<br />channel in Buenaventura Bay. The model was used to
<br />develop engineering alternatives to prevent or reduce the
<br />ongoing sedimentation and therefore reduce the frequency of
<br />maintenance dredging.
<br />Coastal Flood Defense for Meadowlands, New Jersey
<br />Department of Environmental Protection, Meadowlands,
<br />NJ: Technical lead providing oversight services for the
<br />development of hydrodynamic and wave models of the
<br />Hackensack River and Meadowlands wetlands (using the
<br />Delft3D model framework). The project is part of the Rebuild by
<br />Design program funded by the federal government following
<br />Hurricane Sandy. The models were used for a feasibility study
<br />of various measures designed to provide protection from storm
<br />surge flooding.
<br />Coastal Flood Defense for Hoboken, New Jersey Department
<br />of Environmental Protection, Hoboken, NJ: Technical
<br />lead providing oversight services for the development of
<br />hydrodynamic and wave models of the Hudson River and
<br />the city of Hoboken (using the model-based and incremental
<br />knowledge engineering model framework). The project is
<br />part of the Rebuild by Design program funded by the Federal
<br />Government following Hurricane Sandy. The models were used
<br />for a feasibility study of various measures designed to provide
<br />protection from storm surge flooding.
<br />Navigation Channel Sedimentation Assessment, U.S. Army
<br />Corps of Engineers, Norfolk, VA: Technical lead responsible
<br />for developing estimates of future sedimentation and
<br />maintenance dredging rates following the deepening of the
<br />navigation channels in Norfolk Harbor and Chesapeake Bay.
<br />Estimates of future maintenance dredging rates developed
<br />using a spreadsheet-based tool based on various analytical and
<br />empirical approaches described in the literature.
<br />Navigation Channel Sedimentation Assessment, Moffatt and
<br />Nichol, Santos, Brazil: Led a conceptual study of sediment
<br />management problems in the Port of Santos in Brazil. The effort
<br />involved literature review and limited numerical modeling
<br />(using the Delft3D model framework) aimed at developing an
<br />understanding of the hydrodynamic and sediment transport
<br />processes in the port, estuary, near-shore coastal zone, and
<br />inter-tidal wetlands. The study was designed as a conceptual
<br />analysis of the processes affecting sedimentation and shoreline
<br />changes and to develop potential sediment management
<br />strategies. Study presented at an international conference in
<br />Santos, Brazil.
<br />Contaminated Sediment Management for the Housatonic
<br />River Superfund Site, U.S. Environmental Protection
<br />Agency, Pittsfield, MA: Developed hydrodynamic, sediment
<br />transport, and contaminant transport models (using the
<br />environmental fluid dynamics code model framework) to
<br />assess contaminated sediment management alternatives for
<br />the river and adjacent 10-year floodplain. Performed data
<br />analyses to develop initial conditions and boundary conditions,
<br />to understand and parameterize fate and transport processes,
<br />developed linkages with watershed and foodchain models,
<br />and developed model performance metrics. Applied model to
<br />simulate and compare various remedial alternatives involving
<br />technologies such as bank stabilization, capping and dredging.
<br />Effect of remedial technology on sediment and contaminant
<br />transport during and after remediation as well as sediment
<br />stability under a “extreme” flood-event scenario examined.
