My initial reaction would be in agreeance, but the more I think about it, I don't think it is a good match for this channel. Let me explain why. The average length of videos on this channel are about 15 minutes and focus on a single concept with a theoretical description, a scientific experiment/demonstration/simulation and finally a discussion of possible solutions. Discovery Channel and National Geographic have created multiple documentaries about the Delta works and many of them can be found on KZitem. Also a lot of materials are copyrighted. Showing a few seconds of the Delta works like in this video (about 15-20 seconds) is considered fair use...

I just finished working on a project that dealt with storm surges and sea level rise for the next 50 years at a coastal military installation. My team and I had to draft a mitigation plan to save/relocate existing buildings/structures. Let me tell you, it's far simpler to plan for future storm surges when developing than it is to play catch up down the road. Before this project I had no idea just how destructive, and far reaching storm surges can be, but now I am baffled by the seemingly lack of planning/mitigation techniques for so many coastal areas.

@Albert Fels You're correct in that mass renovation, relocation, retrofitting, etc. would be incredibly expensive. Future-proofing new projects, however, is magnitudes less expensive than altering existing ones. For example planning for, and adding a few extra feet of fill to a new plot of coastal land to account for rising sea levels may cost more initially, but it pales in comparison to the costs of flood damage, permanent flood-like water levels, or having to demolish and relocate a building entirely. The next major shakeup in urban planning is climate change. It's already starting to happen with government organizations; it's only a matter of time until private interests are involved. Some countries have already started that even.

I study homeland security and emergency management and storm surges are a regular topic in every class because they can be very deadly and very costly. We examine what went wrong in a community and we collaborate on what we can do to make that community safer and more resilient for residents. Great job on the vid (as usual)! Update: I’m now studying homeland security and emergency management at the graduate level. We dig into these instances in a more comprehensive way and come up with qualitative approaches for mitigating, responding to, or recovering from risks like this.

We went down the channel towards the lock to Cayuga since the lake was rough, and came back. Channel was nice and calm, partly sunny... When we got back to the lake a storm had blown up on the south end... The waves were now 4-5 ft from the wind blowing northward up the lake. It was a crazy ride in a little pontoon boat. Water crashing up over the front.

There's one problem with this video: it doesn't address the social construction of risk. The physical science and engineering aspects of the video are great -- please don't think I'm faulting that! But there's a reason I've witnessed huge differences between attitudes toward hurricanes on the Texas Gulf Coast and attitudes toward typhoons on Guam and Okinawa. Residents of Guam and Okinawa live in a region in which typhoons are simply part of the socially constructed expectations of life. On the Texas Gulf Coast, people regularly deny the physical reality in favor of the social benefits of coastal living. Until we deal with the mutually constructed social reality of risk perception, no amount of engineering will protect us against storm surge -- not because engineering solutions won't work, but because people believe it's not worth the cost.

Although the Great Lakes area does not see hurricanes we nonetheless experience water surging onshore during sustained periods of high winds from a particular direction. They are called Meteotsunamis. It's when steady winds push water towards one side of the lake. Both eastern and western coastlines in Michigan are vulnerable to flooding from sustained wind events. This past year has been a particularly brutal one for such flooding events. Michigan homes from the shores of Lake Sinclair southward to Toledo have been hit multiple times with wind induced lakewater intrusion. Beach erosion has accelerated especially on the western coast of Michigan. One entire small town near Traverse City is considering moving further inland because beach erosion is so bad!

Being a resident of hurricane prone South Florida, the most important thing to decide for myself is the location of myself to the center of the hurricane, the eye. Being north east of the landfall/path of the hurricane is the worst zone, and being south west of the hurricane is the safer zone. Whether the eyewall will come in contact with my location is very, very important for this is where most of the danger occurs, regardless of quadrant. Weather service information before a storm will never be this specific, it becomes a personal information gathering event. Storm surge is much more dangerous in the Gulf because the surge has no where to go but on shore. However, the Atlantic side of Florida rarely suffers from storm surge because of the depth of the ocean floor. The damage here is mainly from wave action.

Another factor that increases susceptibility to storm surge is topography of exposed terrain. An example of this is the Chesapeake Bay: if strong winds from the south occur during a high tide, areas in the north end of the bay near the mouth of the Susquehanna River experience flooding. Add rain to the equation, and the water from the many rivers that empty into the bay has nowhere to go but up; flooding quickly becomes catastrophic. It's far more common than what's reported in national news.

Luckily we did not see any strong wind just a lot of rain. Had we seen wind they did more east of us, i am sure the river would have swelled up to the top from the ocean swelling up. Great video

Storm surge is also caused by low pressure, which you mentioned, but basically treated as irrelevant. A hurricane over the ocean is like a straw in a glass: the low pressure in the straw sucks the water up. That's why, even when the wind from a hurricane has subsided, the low pressure and storm surge can still linger.

Low atmospheric pressure is a pretty small contributor to total storm surge, especially in extreme situations like tropical storms.

You were talking about wind blown waves. Storm surge is a giant dome of water 100 miles across and just an inch or so high caused by low pressure in the storm's center. When it reaches shore, the front of it stops but there is 100 miles of water with momentum still coming in. Water piles up at the shore and can't go anywhere while more comes in. Effect is slow rise for hours. By the time all 100 miles of storm surge has been trapped against the land, it piles up to the 20 plus feet you described. This is like a tsunami where the wave is small but very wide at sea but piles up to enormous height when land and shallow water slow the front of the wave while water from farther back has momentum that keeps pushing more water against the land. Storm drains are made to direct rainwater to the sea but when the seal level rises due to storm surge, water flows the other way, gushing out of the drains and flooding roads and yards before the sea waves move so far inland. Most of your videos are very informative, but this one missed the root cause entirely.

I saw once a graphic trying to explain that sea level rises because of the low pressure of the storm pulling the water up. I'm not even sure this effect is even measurable.

I had the privilege and responsibility for working on the MsCIP with the Mobile District of USACE one year after Katrina hit Mississippi. Storm surge heights were in excess of 20 feet near Waveland, MS and literally nothing withstood that onslaught. Debris piles were 20-30 deep of the remains of homes and businesses along the coast. Groves of pine trees were stripped of bark from the debris washing against them and several Gulf oil platform support tugs were lodged into the forest yards from the coastline. Worse yet were the 10 foot waves riding atop the surge that destroyed everything in their pathway. Evacuation in advance of a hurricane or large tropical storm is the only safe decision.

The most interesting part of this video for me was that the depth of the shelf off the coast has a big role to play. Unfortunately for us humans the thing we value about a safe swimming beach; including a shallow sloping drop-off is probably the least favourable when it comes to reducing storm surge!

A fun video would be to do the calculations for a pumped hydro facility. With Lake Erie being the upper reservoir and Lake Ontario being the lower. A mere 6 inches is a trillion gallons with a height difference of 300 feet it would be the biggest battery in the world by several factors. While the politicsof both the shoreline owners and it being an international border might be insurmountable to ever get done. It would make a great video to do the calculations for electric generation and the practical engineering for sizing & construction of tunnels, penstocks & transmission lines.

Storm surge could also be related to the decrease in air pressure, which causes the coastal waters to be sucked up a bit, causing more serious floods.

Great video! Wind energy does not "move water up the shore". The water "absorbs" the energy from wind that creates displacement within a constant volume. This displacement creates"waves". The waves "running up the shore" is only due to the displacement of medium (water) within a constant volume. That makes it appear that the water is moving up the shore.
