Performance Work Statement Southeast Florida Sediment Morphodynamics

PART 1

GENERAL INFORMATION

1. GENERAL:

This is a non-personnel services contract to perform the measurement, analysis, and forecasting of sediment transport and pathways in order to develop conceptual models that support management decisions for southeast Florida inlets, beaches, and nearshore coastal waters. The tasks include the study and development of three project site specific sand, silt, and/or clay fraction sediment tracer studies, which require interpretative analysis and reporting to enhance understanding of sediment morphodynamics in the project areas. The tasks require the contractor to integrate sediment tracer results into a Delft3D or equivalent model framework for calibration and validation purposes, in addition to the development and production of the Delft3D or equivalent model along with supporting metocean data.

The Government shall not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the Contractor who, in turn is responsible to the Government.

1.1. Description of Services/Introduction:

The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary to perform a Southeast Florida sediment morphodynamics investigation as defined in this Performance Work Statement except for those items specified as government furnished property and services. The contractor shall perform to the standards in this contract.

1.2. Background:

The U.S. Army Corps of Engineers (USACE), Jacksonville District office, has a requirement for technical services to support missions of operation and maintenance (O&M) for navigation and flood risk management (FRM) to identify solutions for long term sediment management and resiliency in southeast Florida. USACE has specific flood risk management and navigation missions which require analysis of sediment movement around inlets and harbors and management of sediments to maintain safe navigation and bolster shoreline storm protection projects. Dredging is the primary technique for management of sediment in USACE mission areas. In addition to knowing where and how sediment is moving naturally, the projects also require an understanding of sediment movement during or as a result of dredging, how dredged sediment secondarily dispersed into the water column behaves, and optimal channel features and beach placement design. Southeast Florida has nearshore and offshore hardbottom habitat ecosystems, and USACE’s goal is to avoid, minimize and evaluate potential impacts of displaced sediment to these resources. In addition to ensuring the environment is protected during operations, another challenge is the lack of sediment resources for FRM projects. Given the scarcity of resources, extraction and relocation of existing sediment resources must be evaluated to determine secondary and long term effects and ensure the sustainability of FRM projects. Numerical modeling is needed to fill the gaps between existing and planned monitoring data and allow for developing and simulating scenarios under different hydrodynamic conditions within the study area. Hydrodynamic, sediment transport, and morphology change monitoring and modeling that includes a large area will provide the Government requisite information to evaluate multiple missions and authorized projects in the area. The services required under this contract will result in delivery of this asset to the Government.

Project Area 1: Lake Worth Inlet (LWI)

Problem Statement: LWI suffers from chronic shoaling with material typically encroaching into the channel from the north, filling the existing sediment trap(s), and eventually impacting navigation in the channel.

Goal: To understand ambient sediment transport and suggest engineering solutions to minimize shoaling within the channel.

Objectives:

1) To collect measurements to describe the ambient sediment transport processes in and around LWI via metocean field work and utilizing sediment tracers.

2) To identify where shoaled material that ends up inside the channel is originating from via direct measurement utilizing sediment tracers.

3) To suggest specific improvements such as the optimal location(s) for additional sediment traps and/or other advanced maintenance measures that could be implemented to prolong dredging requirements and to decrease shoaling within the channel based on conceptual understanding of the sediment transport in the area supplemented with numerical modeling as necessary.

Project Area 2: Port Everglades (PE) Harbor

Problem Statement: PE requires routine operation and maintenance dredging in 2019 and is undergoing final review and assessment for authorized capital improvements (deepening and widening portions of the channel). Additionally, a non-federal sand bypass project is planned and undergoing regulatory review.

Any dredging project in PE will introduce suspended sediment into the water column that could deposit on or otherwise harm nearby hardbottom resources. A better understanding of dredge plume dynamics in this area is needed to best inform planning for the capital dredging project leveraging the ability to collect data during other dredging events.

Goal: To understand dredge plume behavior within PE Harbor to inform capital dredging operations.

Objectives:

1) Collect measurements to describe the overall circulation and to identify ambient sediment transport processes, including fine grained material which may be released during the dredging process, in and around PE utilizing metocean instrumentation for hydrodynamic and sediment transport data collection and sediment tracers.

2) Leverage any dredging events within the area to collect information on the dredge plume dispersal and spillage via metocean observation and sediment tracers.

3) To develop a calibrated and validated sediment transport model for PE and to use that model to simulate sediment dispersal for proposed dredge events, and develop a conceptual understanding of sediment movement and dredge plume dispersal potentials.

4) To utilize numerical modeling to suggest mitigative strategies to avoid deposition on (or other impacts to) adjacent resources.

Project Area 3: Miami-Dade County (M-D)

Problem Statement: M-D suffers from beach erosion, which degrades the barrier island’s main storm protection feature, and the Government has been routinely renourishing the Beach Erosion Control and Hurricane Protection Project (BEC&HPP) over the last 40 + years. Recently, known offshore sediment sources have been depleted requiring sand to be trucked in and deposited on the beach. This has increased costs of the project exponentially, and does not provide for a long-term sustainable solution. The Government needs to know where and why the sand is eroding, where is it going, and what sustainable management techniques can be implemented to better manage current sediment resources without causing negative morphological change. In addition, Baker’s Haulover Inlet and Government Cut Inlet require maintenance dredging to remove shoaled material, and little is known about how these two inlets are hydrodynamically connected and how those dynamics may be influencing the County’s sediment transport.

Goal: To produce an M-D County sediment resource atlas which details sediment pathways, known and possible sediment resources, a model of countywide hydrodynamics, and offers sustainable management techniques.

Objectives:

1) Collect measurements to describe the overall county-wide circulation and wave climate as well as to identify ambient sediment transport processes in and around the inlets and beaches utilizing metocean instrumentation and sediment tracers.

2) Develop a sediment transport and morphology model for the county and project scale including;

a) An understanding of regional natural sediment dynamics.

b) Identify localized sediment dynamics associated from labeled sources of sediment.

c) Conclude spatial assessment of sediment contributions from each labeled source.

d) Quantify the relative portion contributed by natural sources and that contributed from adjacent beach nourishment projects.

e) Identify wave transmission patterns over the continental shelf and subsequent impacts on sediment dynamics.

3) Identify and report on any previously released sediment tracers from Miami Harbor to further conclude sediment transport dynamics from the inlet.

4) Evaluate best management techniques (i.e. nearshore berms, coastal structures, inlet management, backpassing, etc.) to reduce the nourishments needs / interval / costs via numerical modeling and other analysis.

1.3. Scope:

This scope includes metocean and sediment transport and morphology measurements, Delft3D or equivalent model development and application, sediment tracing and sediment sample assessments.

Services include; sediment sampling, metocean measurements of hydrodynamics, waves, and meteorological variables, sediment transport measurements using sediment tracers and a range of instruments over a wide area to define meso, macro and micro-scale processes, data analysis and interpretation, and numerical modeling of hydrodynamics, waves, sediment transport, and morphology change of beaches, inlets, and coastline on the regional, county, and project level scale.

5.3 Task 3: Sediment Tracing

The contractor shall provide the proposed locations, type, quantity, color for unique sediment (sand, silt and/or clay) tracers for each project area to address the project specific PWS requirements (Sections 1.2 and 5.5). The contractor shall ensure that the sediment tracers assimilate the properties of the native sediment particles and act as native sediment under the influence of wind, waves, and tidal currents. All particles need to be environmentally inert and may not contain any substances that are considered a health hazard. Tracer particles shall have the same physical properties and characteristics as the target natural sediment, and to each other and be sufficient for long –term tracking without abrasion, or coloration loss that would lead to misclassification of end results. The contractor shall perform laboratory testing to ensure that size, density, and settling velocity are properly represented for each project area. This includes the very fine grained material anticipated to be released during dredging of rock at PE which may not be present in the ambient sea bed. An ISO-9001 certified laboratory (or comparable equivalent) is required to process sediment tracer concentration and tracer particle sizing to ensure continuity of interpretation and analysis for all sediment tracer samples.

The Government will review and provide comments and the final report shall be submitted as part of the Final Report Package in Task 5.

5.4 Task 4: Delft3D (or equivalent) Model Package

The contractor will develop, apply, and deliver a 3D synoptic scale model (coupled hydrodynamic and wave Delft3D or equivalent model) covering Southeast Florida (approximate area of coverage in Figure 1). The model will use existing large scale wave and circulation models (i.e. WAM, WWIII, COAWST, HYCOM etc.) to drive the boundaries. Nested within the synoptic scale model shall be a higher resolution Delft3D (or equivalent) model at the sub-regional (covering Broward and Miami-Dade Counties) calibrated for hydrodynamics, waves and sediment transport and at the inlet / project scale (for LWI, PE and M-D) model calibrated to study dredge plume dispersal (PE) and sediment transport, cross shore transport and morphology (M-D). The model development will include but not be limited to: setup and development of all model grids; assimilation of all relevant elevation data to define the model bathymetry; derivation of appropriate boundary forcings; calibration of the sediment characteristics;

determination of appropriate bottom roughness as a result of calibration of the hydrodynamics and consideration of local coral effects; coupling across all model components; sensitivity testing of appropriate parameters and sediment characteristics including calibration within a range that does not violate acceptable limits for the physical environment; and routines and procedures to ingest readily available boundary forcing data to drive the model.

The calibration and validation of all models will be documented for each project area prior to production runs and alternative analysis. Upon acceptance production runs and alternative analysis will proceed.

All production and alternative simulations will also be documented and provided as a part of an updated deliverable. All model input and output files, source code, and executables will be provided as a deliverable, refer to Exhibit B. The contractor’s Model Instructor shall deliver the modeling package with up to five (5) days of training to cover; model development, application, how to perform modifications of the model, and simulated scenario testing with the Government. The contractor must show documentation of the development of and application of both regional models coupled with larger scale models that depict large scale physical oceanography features and high resolution, 3D, project scale sediment transport and morphology change models. Appropriate computational resources should be identified.

Calibration and validation metrics for all models will be commensurate with industry standards for water levels, currents, wave heights, wave periods, wave directions, sediment transport and bed level change.

The synoptic model will serve as the parent hydrodynamic model to nested project scale models. The model domain will encompass Southeast Florida and cover Palm Beach, Broward, and Miami-Dade counties. The model will include hydrodynamics in three dimensions with a minimum of eight vertical layers, have a maximum horizontal resolution of ~1 km, and be dynamically coupled with a regional wave model. The model will be set up to be forced by large-scale flows and waves using atmospheric models (WAM, WWIII, COAWST, HYCOM, GFS, WRF, etc.,) and must be able to replicate the complex basic characteristics of the physical oceanography off Southeast Florida including the Gulf Stream and the Florida Current, and any break off eddies. The model will be calibrated to the measured water levels, waves and currents and winds collected during the field campaign. Validation metrics and thresholds will be identified and agreed upon prior to initiating model development. These metrics will include comparison between measured and modeled water levels, currents, wave heights, wave periods, and wave direction. Acceptance of the model products will be based upon these metrics which will be derived from past studies, applicable Corps guidance and peer-reviewed literature. Relevant pre- and post-processing scripts used to generate boundary forcing from publically available data sources, generated input files and output plots and data shall be transferred to the Corps in the final package deliverable.

Nested within the synoptic model will be a Delft3D or equivalent coupled hydrodynamics and waves, and sediment transport model for Broward and Miami-Dade Counties. This meso-scale model spanning Broward, and Miami-Dade counties will be driven by the synoptic model. The model shall include Port Everglades Harbor, Baker’s Haulover Inlet, Government Cut, north Biscayne Bay and shall be developed, calibrated and validated for hydrodynamics and waves and regional sediment transport pathways as evidenced by the geomorphology of the region. The model will include hydrodynamics in three dimensions with a minimum of eight vertical layers and an average horizontal resolution of under ~150

m. The goal of the model is to provide a broad overview of circulation in Broward and Miami-Dade counties and to inform sediment movement from Broward County into Miami-Dade County. This model will also serve to downscale synoptic scale results to the project scale.

The contractor will develop, calibrate, validate, and apply a Delft3D or equivalent coupled hydrodynamics, waves, and sediment transport models at the project scale for LWI, PE and M-D.

The LWI model will be developed to address navigation concerns related to rapid infilling of the sediment trap and frequent maintenance dredging of the inlet. Coupled with metocean data and the sediment tracer study this model will be used to identify alternative structural and sediment trap configurations to reduce the amount of shoaling of the navigation channel. The model will likely be a direct child model from the synoptic scale model and be calibrated and validated to collected field measurements.

The PE model will be developed to support the Operations and Maintenance dredging activities at Port Everglades and may be used to inform the Navigation Improvements Project where the Port Everglades Channel is being deepened and widened. The model will be nested within the larger parents models to ensure large scale forcing is captured at the project scale. The model will be calibrated to the measured water levels, waves, currents, and sediment transport and sediment tracer data collected during the field campaign with high emphasis on the vertical current structure as it relates to dispersal and fate of material in the water column. The validated model will be capable of replicating the pre-project conditions. The model will be capable of being applied in production runs to answer questions related to the areal extent and concentation of the plume generated by dredging activites and the suspended sediment within the plume. Nearfield models of plume dispersal (numerical, analytical/empirical, and/or statistical) will need to be coupled with the farfield PE model to accurately capture the behavior of the plume and spillage associated with different dredge equipment.

The M-D County project scale models will be developed with direct consultation with the Corps. Delft3D or equivalent models are anticipated to be developed for at a minimum Bakers Haulover and Government Cut to examine sediment transport within these inlets and to inform better managment. XBeach (or equivalent) models will be developed for portions of the federal beach projects to examine cross-shore and alongshore transport of beach material. Additional modeling scenarios may include examining the effectiveness of nearshore berms and coastal structures in reducing the need for beach nourishment, winnowing of fines from nearshore berms, and overall effects on nearshore circulation and sediment transport. All model results will be combined with information gained from previous tasks to develop a M-D sediment atlas.

The contractor shall submit a final model package deliverable for each project area in electronic medium, to include CD, DVD and/or external hard drive. The Government will not accept USB thumb drives.

5.5 Task 5: Final Report Package

The contractor shall submit a final report package for each of the three project areas that directly addresses the Government’s problem statements, goal, and objectives (refer to Section 1.2). The contractor’s final report shall include the Sediment Tracer Study report and Model calibration/validation report.

For LWI the contractor shall include an assessment of sediment trap optimization that would minimize material encroachment into the channel, and where any additional traps should be located and to what approximate depth, or alternatives for advanced maintenance. The contractor shall provide a review of dredging intervals at LWI and recommendations for how to decrease frequency of dredging needs utilizing results of the sediment tracer study and knowledge and/or data of sediment transport and hydrodynamics of the area.

For PE the contractor shall include a dredge plume dispersal conceptual model and model results for both operational and maintenance dredging and captial improvement dredging scenarios. The report shall recommend mitigative techniques to avoid dredge material deposition on adjacent resources utilizing metocean data and Delft3D model runs to determine optimal dredging windows and techniques.

For M-D the contractor shall include a Sediment Transport and Resource Atlas for the County as part of the final report package. The atlas shall provide information on sediment movement throughout the project with a focus on the inlets and the Federal BEC&HSP project. The atlas shall recommend where and how to find suitable material that may have different end uses (Dune material, beach/intertidal, nearshore, etc.) and where this material may be transported to. The atlas will provide an overall understanding of hydrodynamic and sediment processes within M-D as well as solutions for the successful management of sediment within the inlets and on the beaches. The report shall outline the most optimal renourishment interval approach, where and what quality material should be placed, what structures should be built and where, and how this approach will increase the County’s overall resiliency to storm surge and hurricanes and decrease the need for future renourishment.

The contractor shall provide two (2) hard copies of each project area Final Report Package to the Corps for both draft and final versions. Once the draft reports are submitted, the Corps will provide comments.

The contractor shall then submit the final reports within 30 calendar days of receipt of comments.
