It's done to prevent flooding after major rain events. The beach is not being destroyed.

It's a sand bar not a beach and they breach it regularly every year to prevent flooding upstream.

Used to do this with my friend as a little kid. The lifeguards let us borrow the shovels and everything. Growing up in Hawaii was the shit honestly

This was the way to DRAIN THE RIVER from being destructive…. the BEACH IS NOT BEING DESTROYED. Thank you. 🏝🏖🏄‍♀️🏄‍♂️🏄‍♀️🏄‍♂️🌊🌊

Waimea Bay River on Oahu, people have been doing this for years. If it gets really flooded the river waves and current are crazy

Hahaha, beach is fine. They do this several times a year.

Ive seen other videos on this. It happens naturally but for that to occur it floods property inland. So the residents help it by doing this and preemptively stop any flood damage. The beach heals itself and the process continues.

Who says the beach is destroyed? That is absolutely ridiculous.

After putting the title on the video, the publisher glued their head to a painting. 😂

the beach is completely back to normal within a handful of days. Someone does not know how the ocean works .

Love the fact that you just need to get it started and it'll do the main work for you

Was just at Waimea yesterday... beach was still there.

River breaches are part of the world water cycle. It would have happened naturally anyway. Zero harm was done here.

I used drive by there every week. People dig it out AND the river does it naturally all the time.

Why do so many people who upload videos know nothing of what they say.

The dunes in most places are typically heavily monitored and engineered to the best of our ability to tame nature, to prevent water erosion from destroying an entire beach. This sublet is literally in place to gather and be released instead of constantly adding driftto the dune. Forgive me I forget the name for the math involved something to do with plants being strategically placed to grow these alcoves and prevent the over angling of a beach or it's erosion.

imagine walking down the beach then finding a river in your way that wasnt there before getting back along the same beach

Gotta love when the person making the video knows nothing about what is going on.😂😂😂😂😂😂

This is needed to sustain the ecosystem upstream. Large pools and lakes near the ocean cause flooding up the rivers and streams, so this process is almost like a pressure release for a dam. It keeps everything in check. The beach will be back to normal in a few days or a week. Once the water drains, the sand will reform into a beach line and the process will repeat every year.

Lol rivers move, sand moves. My home beach never looks the same week to week. Love watching the groms dig out and make it happen!

Beach is there. Just one small channel of water flowing out. What's the effin Drama for 😂

A river going through the beach! That's fkn awesome

We tried to do this for midnight Pass back in the 80s. The pass got closed by the actions of some rich homeowners. Apparently, their properties built right on the edge of the pass was more important than having a functioning pass. Amazing.

And then, by the next high tide... it healed itself 🙏

I have loved in Honolulu for 40 years. This is not beach destruction. It’s a natural occurrence. I am also a civil engineer and an expert in river engineering

Listen up twitter users, this is done to prevent flooding. The sandbar comes back at high tide. If it didn’t, there wouldn’t be a beach there would be an estuary.

The beech would have still been destroyed when the river topped the beach. It is more likely that the rough sea in a storm dumped sand creating the beach to start with and blocked the river that was already there.

Jamie you're always diggin out Waimea or riding it...

Nobody started the music. 🤙🤙

I do the exact same thing with my mashed potatoes and gravy...

It's like the subway of the river Where it connects to other 😢

Enjoyed all da local's comments. Listen to them. I've lived here since 1991 and am STILL learning every day

Read the comments done to prevent flooding upstream.

Waimea bay... ay that water got Lepto in there. Hope you no get kakio from that.

For those saying that this isn’t destroying the beach, just keep in mind that it depends. Generally speaking, water crashing into land breaks apart larger rocks into smaller and finer sand, never forming larger rocks again through this process. This process is called erosion, and it’s been happening across almost all coastlines. Doing this may help our properties, but speeds up erosion and receding coastlines. They may be doing this for years, but do people realize how much human activity have caused an unnatural change in our environment? If you guys look at the structure of a lot of beaches, you would actually realize that after a certain point of gradually deepening slopes, there’s generally a “cliff” where the ocean gets really deep all of a sudden. If go far enough from the shore, you might realize that in some beaches. That being said, a lot of people think the beaches heal naturally on their own, but in reality, most beaches don’t do that in the way they think it does and depends on many factors too many of which includes natural disasters, tectonic movement over time, water current direction, etc... There’s actually a lot of room for the sand in the sea floor, especially once it reaches that dip, so erosions generally move the sand outward and levels the sand off. There are moments and mechanics where sand gets pushed back onto the land, but it depends as mentioned earlier and generally sand gets further out. Even though we think the beach is healing most of the time, it’s generally an illusion in which it’s simply leveling off the loose sand. Even though we think the oceans look like it’s always pushing sand towards us, a lot of people seem to forget that the tides recede as well, pulling the sand along with it. As the sand from receding coastlines level off, it’s actually allowing more water into land since the displaces the volume of water further up as more sand sinks towards the sea floor, allowing the flooding to occur more often, as you see here. Moreover, a lot of the people don’t realize that a lot of the sandy beaches we go to are man made and maintained by the government from offshore sand. Otherwise, a lot of natural beaches would look more rocky like California or European coastlines (however that depends on the natural geology of the location in the end). So people thinking that all beaches heals itself naturally, well, it might as well be unnatural for that beach to be there in the first place. Just look up receding coastlines and beach maintenance. It’s more than just climate change.

You know your chill beach day is ruined when these guys show up.

This poster obviously is not from Oahu! LOL

People just have to judge shit they know absolutely nothing about.

Times when plans didn't go as planned

This is temporarily destroying the beach, but it actually keeps the beach there longer in the long run. Plus it’s just flat out fun to surf and or boogie board.

Theyre too scared to go out and catch some REAL WAVES.

Long live the destroyers!

Actually everyone is wrong this happens after a major storm it’s called a River Break . It’s happens when a storm and high tide come in and blocks off the area with a ton of sand creating a damn . Usually locals will did a trench to the ocean when the water gets to high inland . Which they gets some sweet waves

Shock and outrage as water flows into the ocean! 😲

Ahupua'a

imagine being like 80 going on a nice walk on the beach and on ur way back to your car you see this

I promise you... The dude posting this knows EXACTLY what's going on. He also knows the way to drive traffic to his channel is via engagement. People LOVE to comment about how much they know...even more so when they think they can look superior by "correcting" someone. Time to take the L and subscribe...he's the owner of this W.

Anyone who has been there knows this has been going on for years. The water has to be drained to make room for the rainwater that comes from up mauka. Jamie and his crew have been surfing this river break for years.

idk, still looks pretty nice to me.

OK Karen It will be a beach again tomorrow morning relax

This is not destroying the beach. Its opening the waterway for an existing creek/river to prevent flooding & allow fish like salmon and steelhead to migrate upstream to spawn in fresh water. These people just enjoying the process hopefully they will be safe about it as they enjoy the day and not leave a garbage mess behind when they are finished.

One day that will be a prime fishing location

All the kooks explaining it to Jaime 😂

Why would you do this. Is it, just for fun or is there a responsible reason for diverting an entire river system in to the ocean.

Looks like a blast let them have fun plus their helping out as well

All Haole's NO Hawaiians or Kamaainas.

Karen, I thought we asked you to stop

For anyone wondering, the river would have naturally crashed down so this isn’t illegal as they are only speeding up the process

Not damaging the beach, but saving it. Without it being done , other issues will persist.

These humans clearly are not concerned about climate change

Yall just haters easy fix

Those subtitles were placed to perfection👍🏼

The residents of Carmel-By -The -Sea in Monterey, CA used to dig from the beach to the Carmel River to encourage salmon spawning.

Never a good idea to do

WOW. Learn something new everyday. I had no idea that could happen.

Nature has its own way ,I don't see any threats to anything at all

Bro didn’t change history He changed geography (skull emoji) (He changed Google Map by just destroying the beach)

All the fresh water fish like: dam, dam, dam!

People not realizing that Jamie O’Brien, the one who surfs this frequently, is the one who posted this video…this is so obviously sarcasm 😂

Say "now this beach is destroyed" as if a controlled breach is worse then an unexpected one that catches ppl unaware and that could cause hurt or worse. Plus, nature has been destroying( and creating) beaches for millions of years, so there is that.

Him - now this beautiful beach is destroyed Me- this now a more beautiful beach than before Who agree 👇

Naaaah the beach is fine it looks even better and more beautiful 🤩. Looks like a flowing natural river is flowing into “The beautiful 😍 beach” 🏝️

sand grows back like plants. its good. not destroyed.

I was just there, don't worry, it's all good, the coast is still there.

Happens at every estuary.

Waimea Beach was greatly changed about 100 years ago when businessmen took the sand from this beach and transported it to Leeward O’ahu to create the man-made Waikiki Beach.

Bro that made it look better.. imagine the photos there, also if they build a bridge on top 😍

I love this song, it's so calming.

Humams thats how everything we touch we destroy 😢

They created a home made Flow Rider which is pretty badass but the locals who use that beach are definitely gonna be super pissed and I don't blame em If it was my beach and I showed up to that I would be livid and looking for asses to beat 💯

Bro made an estuary with that 💀

After a few storms the sad goes back into its place and the have to do this every year to prevent floods

CHANGE THE TITLE!!! It's flood water. They have to do this, and it doesn't hurt the beach.

Bro unlock a new ocean on the map 😂💀

"What are you in jail for?" "I created a new world."

Aaaah!!! is this where short wave radio started 😊

I would love to find a beach that does this annually. It would be so cool. The beach I go to is just the beach, and doesn't have a pond/lake behind it.

It comes back by itself. The waves crashing on the beach deposit sand and it builds another estuary

Honestly, this actually makes the beach more beautiful to me

As a teen I always wanted to do this. Only bad thing about this is rip currents and also the water gets dirty for a day

How this beach got destroyed is a statement. It's not a question.

That's called FLOOD CONTROL KAREN!😂😂😂

So much fun! I loved this as a kid when I was little.

Bro's be like "uh what dothen?" 💀

"how did you got in prison?" "I stole someone's money, how about you?" "I tried to make a new continent"

township fire chef sees that tru google maps fire chef: hey thereee

Great job, and idea. Can be dangerous, someone could accidently drown. Now if only this idea used all over the world. Go out when it's raining, or before, and dig ditches. Clean out ditches! Keeping them clean, redo them every so often.

Destroyed? Literally coolest beach ever.

They do this all the time they’re 100% allowed to after heavy rains it floods and this helps prevent flooding down stream where it can damage farmlands and homes keep the water in the ocean and out of peoples basements and farms is a good idea especially if people can have so fun doing it and if the worse thing that happens is there’s a gap in the beach for a day or 2 who cares they comes back after it drains and level it back out.

Thanks to everyone who cleared this up and told the real truth.
