Breakwater in St Malo, Bretagne. Made of thousands of oak trees stuck in the sand in front of the ramparts, and eroded over the years.

To the best of my understanding (I'm no harbormaster, but I vaguely remember some hydraulic engineering classes from college, and I just now discovered CoastalWiki.org): wharves, quays, jetties, and piers are all used for unloading ships. A similar structure not used for unloading ships (and thus usually not walkable on top), but rather to control coastal erosion and/or partially enclose and protect a harbor, would be a breakwater.

You're probably familiar with the idea of a seawall, which is a type of breakwater that is typically built parallel to a shoreline, right at the land-water interface, or possibly above a beach. They're typically constructed of stone or concrete blocks, poured concrete, interlocking concrete blocks such as tetrapods, riprap, sandbags, gabions, etc.

A groyne is a type of breakwater that typically extends straight out from shore, and is often but not always constructed of wood.

A mole is another type of breakwater that can extend straight out from shore, but can also curve around to parallel the shoreline. A mole is typically constructed of fill.

In case you’ve ever been confused which is which.

What is the difference between ocean and coastal engineering?

Ocean engineering and coastal engineering are both specialized fields within civil and environmental engineering that focus on different aspects of marine environments. Here are the key differences between the two:

**Ocean Engineering**

1.Scope:

Broad Focus- Ocean engineering covers a wide range of activities and technologies related to the exploration, utilization, and protection of the ocean.

Deep Water- Primarily concerned with deep-water environments, beyond the immediate coastal areas.

2. Key Areas of Study:

Marine Structures- Design and construction of offshore platforms, underwater pipelines, and subsea systems.

Oceanography- Study of physical and biological aspects of the ocean, including currents, waves, and marine life.

Renewable Energy- Development of technologies for harnessing renewable energy from waves, tides, and offshore wind.

Underwater Vehicles and Robotics- Design and operation of remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) for exploration and monitoring.

Environmental Monitoring- Assessing and mitigating the impacts of human activities on marine environments.

3. Applications:

Oil and Gas Exploration- Designing and maintaining offshore drilling rigs and production facilities.

Marine Renewable Energy- Implementing offshore wind farms and wave energy converters.

Subsea Infrastructure- Laying and maintaining underwater cables for telecommunications and power transmission.

Marine Research- Developing tools and methods for scientific research in oceanography.

**Coastal Engineering**

1.Scope:

Focused Scope- Coastal engineering focuses on the interface between land and sea, particularly in coastal and nearshore areas.

Shallow Water- Primarily concerned with shallow-water environments and coastal zones.

2. Key Areas of Study:

Coastal Protection- Designing structures like sea walls, groins, and breakwaters to protect against erosion and flooding.

Beach Nourishment- Adding sand to eroding beaches to maintain their width and protect coastal properties.

Harbor and Port Engineering- Designing and maintaining ports, harbours, and marinas for safe navigation and docking.

Hydrodynamics- Studying the movement of water in coastal areas, including tides, waves, and storm surges.

Sediment Transport- Understanding and managing the movement of sediment along coastlines.

3. Applications:

Flood Défense- Constructing levees and floodgates to protect coastal areas from storm surges and sea-level rise.

Erosion Control- Implementing measures to prevent coastal erosion and preserve beaches.

Habitat Restoration- Restoring natural coastal habitats such as wetlands and mangroves to enhance resilience and biodiversity.

Coastal Development- Planning and managing the development of coastal infrastructure and communities.

Marine and Coastal Engineering ensure the sustainable management of resources

Ocean Engineering deals with broader and deeper marine environments, focusing on offshore structures, renewable energy, underwater technology, and oceanography.

Coastal Engineering is more focused on the land-sea interface, addressing coastal protection, erosion control, harbor engineering, and sediment management.

Both fields are essential for sustainably managing and utilizing marine and coastal resources, but they apply different techniques and knowledge bases tailored to their specific environments.

Powering the Waves: Small Marine Engines Market Insights

The small marine engines market value will reach USD 11,696.1 million by 2030 from USD 7,967.5 million in 2022, at a 4.9% CAGR. This growth can be credited to the growing demand for numerous kinds of boats utilized for recreational and relaxation events, and the growing coastal tourism for water activities including yachting, boating, and fishing.

Furthermore, the leaning toward the water-based leisure industry has been on the surge because of the increased expenditure on water-associated activities by a chunk of the populace. Also, the sense of better-quality mental health because of the quality time spent during water-based activities is a main factor for the booming boating demand, which, ultimately, quickens the outward and inward-placed engines of marine vessels.

The mounted customer involvement in marine fun activities is offering worthwhile development opportunities for engine demand. In the past years, marine tourism and relaxation activities like yachting, power boating, and sailing, have experienced a significant surge, because of the growing disposable income of consumers. Moreover, rapid development in adventure tourism is helping water recreational activities.

As per a government-issued research article, above 50 million Americans went fishing, including artisanal fishing, commercial, and artisanal fishing, in 2021, which generated a profitable demand for outdoor or inner-placed motors in marine recreational vehicles. the recreational boats category, on the basis of the application segment, generated approximately USD 3.5 billion in revenue in 2022. And, a surge in demand for technically progressive fishing boats is projected to drive the development of the industry for engines and propulsion systems across the forecast period.

In 2022, the outboard motor category dominated the industry, and the category is also projected to advance at a CAGR of 5% in the coming years. This is mainly because of the technical advances, the requirement for outboard boats is projected to increase significantly in the coming few years.

Oxfam condemns in the strongest terms the killing in Gaza today of four water engineers and workers from the Khuzaa municipality who were working with our strategic partner the Coastal Municipalities Water Utility (CMWU). The four men were killed on their way to conduct repairs to water infrastructure in Khuzaa, east of Khan Younis. Despite prior coordination with Israeli authorities their clearly-marked vehicle was bombed. Oxfam stands in solidarity with the CMWU, their partners and the families of the victims.  Their deaths deepen the catastrophic humanitarian crisis in Gaza where access to clean water is already severely compromised. Dozens of engineers, civil servants and humanitarian workers have been killed in Israeli airstrikes throughout this war. They were all working on essential services to keep Gaza's fragile infrastructure running. Despite their movements being coordinated with the Israeli authorities by the CMWU and the Palestinian Water Authority, to ensure their safety, they were still targeted.  Attacks on civilian infrastructure and those who maintain it are clear violations of international humanitarian law. Those responsible must be held to account. Such attacks are part of the crime of using starvation as a weapon of war.

🧃 How to Develop a Vibe AND a Plot (aesthetic doesn’t cancel arcs. let’s balance them.)

hey you. yes, you. the one with the moody playlists, the 73-tab Pinterest board, and a half-written draft that just keeps…vibing in circles.

if you’ve ever written 10k of immaculate vibes but couldn’t tell anyone what your story is about, this post is for you. because here’s the thing: ✨ aesthetic is not a substitute for stakes. ✨

let’s talk about how to keep your ✨vibes✨ and actually have a plot that moves. no ✧ fluff ✧ just structure, character arcs, and some lovingly blunt advice from your local writeblr gremlin (me).

🌊 1. aesthetic is a result, not a premise

the most common mistake i see is starting with a vibe as the story. like:

“sad girls on the beach in 1996”

“a cursed forest full of dead gods”

“a pastel academic rivalry with secrets and sexual tension”

cool. great. love that for you. but… what’s the story? what’s happening?

✨vibes = setting + mood + tone. ✨plot = choices + consequences + change.

your aesthetic can inspire the story (please keep making playlists. i love them). but don’t confuse the feel of your world with the function of your plot. start with tension. stakes. character flaws. emotional damage. that’s the engine. the aesthetic is the paint job.

🎯 2. define your “emotional throughline”

okay, so you’ve got an aesthetic. what’s the emotional core of it? your plot should orbit a single emotional question, like:

will this character ever let themselves be known?

what does it take to unlearn loyalty?

is love worth destroying something sacred?

start with that. then attach aesthetic scenes to it.

🧩 pro tip: aesthetic scenes are more powerful when they contradict or complicate your emotional throughline.

ex: your story’s about loneliness? show them at the loudest, busiest party. story’s about grief? show them smiling in photos while everything breaks behind the lens.

aesthetic is stronger with irony. contrast. juxtapositions. don’t just bathe the reader in vibes. weaponize them.

💥 3. let your aesthetic hurt your characters

whatever your aesthetic is--soft academia, vaporwave horror, regency witchcore, don’t make it just a backdrop. make it an obstacle.

your setting should create problems. friction. conflict.

if it’s a sleepy coastal town: what’s festering beneath the quiet?

if it’s a hauntingly beautiful forest: what does it take from people?

if it’s a cursed mansion: what happens to the girls who stay too long?

every time you design a pretty place or moody visual, ask: ❓ how does this setting test my characters’ beliefs or desires?

because then your aesthetic drives the story forward instead of just decorating it.

📚 4. develop plot like a playlist: structure the escalation

your aesthetic playlist has structure, right? (don’t lie. i know you’ve got a specific song for act 3 heartbreak.)

plot works the same way. it’s not a mystery. it’s escalation.

you want a structure? here’s a dead-simple one:

give your main character a desire (internal & external)

give them a reason they can’t have it (flaw, fear, lie)

make them try anyway (rising stakes)

make it cost them something (midpoint shift)

force them to change or break (climax)

let that change play out (falling action / resolution)

that’s it. apply that structure to your vibey little story and suddenly it’s a book.

👁‍🗨 5. plot is what they do - vibe is how it feels

don’t choose one. you can have both.

you can have a soft lighting scene on a rooftop and the secret betrayal reveal. you can have dreamy prose and broken character dynamics. you can give me worldbuilding so lush it smells like petrichor and rot and still give me a plot twist that leaves me feral.

you just need to be intentional.

every scene = a purpose. every aesthetic = an angle. every image = tied to stakes, desire, or change.

✨ that’s the difference between “ooh pretty” and “oh my god i can’t stop thinking about this story.” ✨

💌 so in conclusion:

start with an emotional arc

let your aesthetic scenes earn their place

make your world fight your characters

escalate, escalate, escalate

and stop hiding a lack of plot under “vibe” like a glittery throw blanket over a broken chair

you’ve got this. now go write the beautifully messy, aesthetic and emotionally devastating story you were meant to.

i believe in you.

Almanara Castle, Historical Landmark in Tatrosa | Museum and Wedding Venue (NO CC)

The Almanara Castle (Also known as "Almanara Al-Tartos", or "Alcazar of Tartosa")

Almanara Castle, once part of the grand Qasr Al-Zayl al-Tartos, was the last refuge of Emir Jabar Al-Tartozi II before the fall of the Emirate of Tartosa in 1497. Spared after the siege, it later became a royal villa and was declared a cultural heritage site in 1876. Now a museum and wedding venue, Almanara offers a glimpse into Tartosa’s past with stunning coastal views.

Lesmana Enterprise led the restoration efforts after the 2021 Tartosa earthquake which damaged the castle, restoring it to its former glory.

The Last of its Kind in Tartosa

This picturesque castle was built in the late 14th century during the early years of the Tartosan Emirate rule by Al-Simhara sulanate engineers.

Its arabesque-moorish architecture is a reminder of a much more different, by-gone era of Tartosa's deep history.

Well Preserved, As if it was Built Yesterday

Our team of highly skilled engineers, historians, craftspeople, and archeologists ensures that the Almanara Castle retains its charm for centuries to come.

From intricate archway designs, geometric tileworks, centuries-old plasters, to water features that had worked for the past 600 years without the use of eletricity, we made sure visitors would experience Almanara Castle the way the Emirs of Tartosa and his royal court had experienced it centuries ago.

The Hall of Jenane

During the rule of Emir Hamid I (AD 1401-1429), Almanara Castle was repurposed as a private quarter of his daughter Amirah Jenane Al-Munr, who added more geometric tilework to the castle, adorned in her favorite azure and tosca colors to every edge of the estate.

In 1415, Amirah Jenane had her wedding in this very hall, where dignitaries from neighboring kingdoms like Kingdom of Windenburg, Grand Duchy of Champ-les-sims, and even norther simlandic kingdoms were invited to attend.

Today, the hall of Jenane becomes an exhibition hall that displays the collections of Amirah Jenane, where centuries-old potteries from different parts of the world can be seen, showing the Amirah's love for future generations who visits the castle.

Also, just like Amirah Jenane, you can experience becoming an Emirate royal by having your wedding in this hall too, by arranging the dates from the Museum's website.

The Emir's Exhibition

On the second floor of the main keep, you can find an exhibition of the Emir Jabar II's personal belongings such as weapons, books, and tapestries.

Pieces like the Emir's silver sword crafted by a Ravenwood master blacksmith, or the Emir's Gunpowder-powered broom crafted by a Glimmerbrook 15th century famed gunsmith-warlock is diplayed in this room.

The Azure Sanctum

In the castle's subterrane, is a breathtaking hall called the "Azure Sanctum", a hall with and endless arrangement of pillars and arches adorned in the finest lazuardi tiles and gemstones, with a fountain that had been running for centuries without the help of electricity.

According to historians' records, the Azure Sanctum used to be a place where the Royals would lounge during the hot Tartosan summer, as this room is proven to be -5 to -7 degrees celcius cooler than the air outside.

Now, the Azure sanctum serves as an exhibition hall for wall decorations and the famed "Scales of righteousness", a golden scale used widely in the Tartosan Emirate's Al-Simharan justice system in the medieval era.
