Define the hazard envelope
Pair waves with tide, surge, mean sea-level allowance, currents, storm duration and antecedent beach condition. A single return-period water level does not describe the load case.
Knowledge / Coastal resilience
Coastal resilience and waterfront protection.
Coastal protection is a performance system: offshore forcing, nearshore morphology, structural response, drainage, landward consequences and recovery all matter. A completed structure is only one part of that system.
Protection is a system, not a structure
Beaches, dunes, revetments, seawalls and breakwaters change wave, water-level and sediment response in different ways. Their value is measured against a defined hazard and service objective, not by visual completion alone.
Choose the intervention family
Hold, advance, nourish, accommodate and managed realignment solve different problems. The preferred option must address the dominant failure mechanism without exporting unacceptable erosion or flood risk.
State the service criterion
Acceptable overtopping, crest access, navigation operability, asset damage, habitat function and recovery time are separate limits. Each needs a threshold, receptor and inspection or monitoring route.
Establish offshore waves and water levels, transform them across bathymetry, and account for currents, sediment pathways, shoreline orientation and storm sequencing.
Test run-up, overtopping, reflection, transmission, drawdown and local velocities at the structure, along the crest and across landward drainage routes.
Check foundation, toe, filters, underlayers, armour, crest, transitions, drainage and geotechnical stability as one load path rather than isolated quantities.
Map receptors, residual inundation, access loss and cascading utility effects, then define inspection triggers, repair resources and the time needed to restore service.
Five coastal systems require different acceptance records
The acceptance record changes with the intervention. Volume, length or contract completion cannot substitute for the geometry and performance measure that the asset was designed to deliver.
Ocean City: contract quantity to accepted beach profile
The current contract sets more than 1.6 million cubic yards and USACE records the dredge mobilised. The ledger now needs daily placement, cumulative quantity, borrow-area control, surveyed berm width and elevation, access restoration and USACE acceptance.
Ebeye: quarry release to island handover
Quarry grading, ocean carriage, deep-water transfer and landing are all part of delivery. The final construction record still turns on surveyed chainage and cross-sections, toe and filter inspection, tie-ins, drainage, defects closure and funded maintenance responsibility.
Gorée: protect the scope behind each percentage
The published 82%, 85% and 75% figures use different dates or scope boundaries. Segment completion for the eastern and western works must be read alongside the school wall, mosque slope, UNESCO validation, promenade, landscaping and the proposed finance extension.
West Point: permit secured, works evidence still ahead
Finance, an approved ESIA and the March 2026 environmental permit establish a serious project. The next commercial record is the works solicitation or award, followed by notice to proceed, quarry approvals, mobilisation and a baseline shoreline survey.
St. Joseph: field activity before performance findings
The 83,000-cubic-yard campaign and perpendicular nearshore placement establish the 2026 field test. Bathymetry, turbidity, sediment movement and shoreline response will decide what the method achieved and whether it supports wider use.
Failure often begins at an interface
Armour size receives attention because it is visible. Many consequential defects start elsewhere: at the toe, through an incompatible filter, at a transition, behind a wall or where drainage has no safe outlet.
Toe and foundation
Scour, trench tolerance, weak founding material and differential settlement can remove support before the armour slope appears distressed. Foundation level and toe embedment need survey control and exposure records.
Filter continuity
Granular filters and geotextiles must retain the base while passing flow. Segregation, puncture, open laps and missing transition zones allow internal erosion that surface inspection may not reveal.
Returns and tie-ins
A robust central section can still be bypassed at a buried end, outlet, access ramp, quay interface or change in crest level. Drawings and as-built surveys must close every transition.
Crest and drainage
Overtopping damage depends on discharge, flow depth, velocity, duration and the landward surface. Crest details, rear-slope protection and drainage paths belong in the hydraulic design.
Quantities need engineering boundaries
A correct number can still misstate delivery when its location, date, material state or acceptance basis is omitted.
Ebeye's roughly 65,000-tonne intended armour use and approximately 80,000-tonne supplier record describe different parts of the chain. Reconcile both with certified installed quantities.
Ocean City's current 1.6-million-cubic-yard contract is separate from the completed 2022-23 cycle. Keep contract, produced, placed and accepted volumes in separate columns.
Ebeye's 1.81 kilometres of new seawall sits inside a 2.1-kilometre programme indicator that includes 300 metres of existing protection. State what is new before comparing lengths.
Every percentage needs an as-of date, denominator and excluded scope. Gorée shows how protection works, landscaping and overall programme progress can produce valid but different figures.
Construction control is part of performance
Design assumptions only survive construction when source material, placement sequence, geometry and hidden layers remain traceable.
For armourstone, verify grading, density, durability, shape and quarry production consistency. For nourishment, verify grading compatibility, fines, contaminants and borrow-area limits.
Open filters, incomplete toes, exposed excavations, temporary accesses and partly closed beach sections can govern risk during storms. Hold points should match the forecast and workable-weather plan.
Link delivery tickets and vessel logs to chainage, level, layer and survey. Material received on site is not the same as material placed within tolerance.
Capture profiles, crest and toe levels, transitions, drainage outlets, beach volumes and photographs before handover so later movement can be separated from original nonconformance.
Resilience is observed over an event series
A calm-weather completion survey proves geometry, not resilience. Useful performance records pair the loading history with the condition and service response that followed.
Event loading
Record water levels, wave conditions, duration, direction and whether several storms arrived before recovery. Without exposure data, condition changes cannot be interpreted consistently.
Residual condition
Repeat fixed profiles and inspections at toes, transitions, crests and drainage points. Distinguish tolerable reshaping from progressive loss of section or function.
Adaptive response
Beaches, dunes, wetlands and hybrid systems are expected to move. Their monitoring plan should define performance metrics, intervention thresholds and replenishment or repair actions before an event.

The July coastal protection monitor compares six named projects on a consistent basis: intervention type, delivery stage, quantity boundary and unresolved acceptance evidence. Each conclusion links back to its project record.

Granville's Herel breakwater repair has an unusually clear award and start record: EUR 5,897,585 in BOAMP, a Marc-NGE-ETPO delivery group named by the owner, a 25 August 2025 site start and a nine-month programme. The planned end-May 2026 acceptance date has passed, however, and the current official record still lacks an actual completion or acceptance notice, measured repair quantities, defects status and final account.
7 August 2026 / 4 sourcesBraek's replacement pipeline is contracted but not publicly handed over
Grand Port Maritime de Dunkerque concluded a EUR 1,720,365 excluding-VAT contract with Baggerbedrijf de Boer B.V. to remove and replace the submerged sand-discharge line in front of the Braek dike. The tender required service by 31 May 2025, while public project records publish no physical completion or acceptance milestone. A 2018 predecessor award shows the same contractor installed a 1.5 km line intended to support annual nourishment of 0.5 million to 2 million m3.

14 October 2026 / 11 sourcesWarrawong's live seawall contract still needs a completion record
Warrawong Parklands has moved from a failed timber seawall and open tender into a live AUD 3.814 million construction contract with Civil Constructions. NSW Planning reports work underway and targets completion by year end. The public record still does not provide the installed rip-rap quantity, habitat-feature acceptance, final value, practical completion or reopening evidence needed to close the project.
5 August 2026 / 4 sourcesMoss Landing has post-dredge surveys, not a full closeout
Moss Landing Harbor now has a traceable award, physical work windows, named dredging fleet and published post-dredge surveys. Ahtna's current official obligation is USD 16.037 million and the contract period ended on 23 January 2026. The public chain still stops before final dredged quantity, accepted jetty repairs, practical completion and certified final value.
5 August 2026 / 7 sourcesLibertad dredging is reported complete without published package closeout
Rayman Builders signed the USD 1.071 million Libertad Outfall dredging contract on 6 October 2023. The Philippines Commission on Audit identifies the same package as DPWH contract 22Z00033, records a PHP 60.833 million contract cost and lists PHP 60.665 million in construction in progress at 31 December 2024. A November-December 2025 World Bank mission reports that all eight DPWH dredging contracts were completed. That supports completed contract status for the group that includes Libertad, but it does not publish this package's measured volume, sediment destination, as-built geometry, hydraulic clearance or DPWH acceptance.

World Bank contract record 1881500 names C. O. Williams Construction Limited at USD 3,338,256.29 for Sugar Berth seawall, pavement and revetment repairs. Yet a procurement plan revised in December 2025 still called the works Pending Implementation and planned a January 2026 signature, while the API reports a September 2025 signature and April 2026 no-objection. Field mobilisation and completion remain unconfirmed by a dated official record.

TED confirms that ETEP signed the combined fishing-port and coastal-esplanade contract for TND 20,018,762.19 on 28 April 2025, with a stated 28-month duration. The EIA exposes a substantial marine package, including a 493 m breakwater and 5,400 m3 of planned dredging. Yet the public delivery chain stops short of technical works: July 2025 reporting described site-facility locations and pending administration, and parliament still described the project as delayed in February 2026.
9 August 2026 / 5 sourcesNewell Beach physical completion lacks a published final account
TMR confirms that Newell Beach's ramp, fixed walkway, fishing platform, rock wall and dredged all-tide access were complete in May 2022. The commercial record is less closed: CN-17011 rose from AUD 2,560,154 to AUD 2,603,835 after a disclosed variation; RECS held a separate AUD 44,000 inspection contract; and completion reporting used an AUD 3.5 million whole-facility figure. None is a public final account.
6 August 2026 / 6 sourcesPoona's January target passed before access dredging began
TMR expected Poona's full boat-ramp package to finish by January 2026. MSQ then scheduled approach dredging and foreshore nourishment for 9-27 February and closed the ramp from 16 February while upgrade works continued. The contract disclosure rose from AUD 2,041,001 to AUD 2,448,002, but the variation scope and final account remain unpublished.

Three confirmed base contracts place CAD 14,454,531.96 of Nova Scotia fishing-harbour work under named primes. Zutphen Contractors holds Glace Bay's D1-D11 demolition and steel H-pile marginal-wharf package. Dexter Construction holds Meteghan's floating-dock and pipe-pile replacement. Connors Diving holds Meteghan's separate Wharf 403 concrete-repair and FRP pile-jacket package. The exact sum defines current award scale, while the three contracts retain different methods, terms, work fronts and acceptance records.

A CAD 8,896,913.40 federal award places demolition and reconstruction of Glace Bay wharf structures D1 through D11 with Zutphen Contractors under CW2454987. The replacement changes the structural system from mainly timber cribs to a steel H-pile-supported marginal wharf. The federal contract page fixes the prime, amount and 2 June 2026 to 31 March 2027 period; DFO's earlier navigation filing fixes the Renwick Brook worksite. Neither source establishes site possession, first demolition or first pile.

Two separate contracts now govern Meteghan Small Craft Harbour. Dexter Construction holds CAD 4,292,100.00 CW2462474 through 30 November 2026 to replace three floating-dock systems and associated pipe piles, except the middle set replaced in 2018. Connors Diving holds CAD 1,265,518.56 contract 4500109325 through 31 March 2027 for Wharf 403 concrete removal, repairs and FRP pile jackets.

3 November 2026 / 5 sourcesNga Bay: Hand Over Each Riverbank With Its Drainage Connections
Nga Bay's riverbank and drainage works were proceeding on different programmes in Can Tho's June 2026 progress account. Package 1 covered embankments and Pham Hung green infrastructure, with completion then expected by 31 December 2026. Package 2 covered storm drainage, sewer collection and wastewater treatment, with completion expected in November 2027. Across the scheme, about 3.1 km of new banks along Xeo Vong, Cai Con and Soc Trang connect to a planned stormwater system with 22 outlets and to works at Xang Thoi Lake. That combination makes the drainage connection a specific handover question for each completed bank reach. [1][2]
4 November 2026 / 4 sourcesDuke Marine Lab: Quantifying a Living Shoreline's Elevation Deficit
Duke Marine Lab's living shoreline has retained its granite sill while the water around it has risen. NOAA's site report records consistent sill elevations between the post-construction survey and a 2025 resurvey. Its 2004-24 monitoring summary puts lower-marsh elevation gain at 2.0 mm/year and mid-marsh gain at 0.3 mm/year, against a local mean sea-level rise of 4.5 mm/year [1]. Those measurements describe different maintenance demands within one functioning coastal asset.
5 November 2026 / 3 sourcesLekki: Match Maintenance Dredging to the Beach Sand Budget
Lekki's design connects maintenance dredging to the artificial beach east of the port. A 2023 study by authors at CCCC-FHDI and China Harbour describes west-to-east sand transport interrupted by the port structures, with nourishment intended to replenish the downdrift beach. Its modelled sand supply combines western deposits with material recovered from the basin and channel [1]. A dredging campaign feeding that beach needs both a navigation cut and a suitable fill supply.

Somerset Council's October construction account reports reinforcement beneath the central pier and permanent concrete taking shape. The next interface is between the revised machinery arrangement and the concrete being cast. [1][2]

Mean elevation gains were 13.2 and 7.8 mm/year respectively over the study record through 2021. The lower area gained height faster; the higher area began with 0.10 m more elevation above the same datum. [1]
