Video: A UK coastal management scheme: Lyme Regis (Part 1)

﻿Hi Geographers, and welcome to this course lesson today. Where we're going to be looking at an example of a UK coastal management scheme. We're going to be focusing Lyme Regis, which is on the Jurassic coastline, and fantastic for fossils. I've been fossil hunting. I went with my friends and they were finding all of these amazing fossils. I spent all day and found nothing. So I definitely don't think it's my forte. For today's lesson, all you're going to need is a pen and a piece of paper. In a second I'm going to ask you to pause, and go and get them, and clear away all those distractions around you. Alternatively, you might choose to move to a quieter place so you can focus during today's lesson. Right, off you go and get what you need, and I will see you in a second. Brilliant, right. So the title today is UK coastal management scheme. And then we're going to have a subtitle underneath, which is Lyme Regis. And this is lesson number one of two. So get all that title down, pause it if you need the time, make sure it's underlined and we'll be ready to go. Coastal management at Lyme Regis is going to be split into two lessons. So I thought it was important for you to know which bits we're going to tackle today. Today, we can have a look at where Lyme Regis is, why it needs management, and then we're going to practise some of our map skills. There's going to be a second video that you can watch, which will look at the management that's been used Lyme Regis, and how successful this management has been. This map shows the location of Lyme Regis. It's located on the South coast of England. It's in the County of Dorset over the West hand side. And it's part of the beautiful Jurassic coastline. Tourism is Dorset's biggest industry, and it employs nearly 40,000 people. 65% of these people work in coastal towns like Lyme Regis. In Dorset, tourism brings in 800 million pounds annually, and Lyme Regis is a really popular tourist destination, particularly, for those fossil hunting. They also host many events through the year, like a fossil festival in April, and jazz and blues festivals through the summer. Here we have an ordinance survey map of Lyme Regis. I would like you to tackle these five map skills questions now. Map skills questions come up in the exams every single year. And the more we do them, the more confident we're being. Pause the video now, take as long as you need, give them all you got. Right, let's look through and see how you have done. The first question was, how is a beach shown? You can see that all the way around Lyme Regis, there is a light yellow area by the sea, and that represents the beach. Which costal landform is shown at Broad Ledge. So Broad Ledge is shown in large there, and it's a wave cut platform. Here's a picture of Broad Ledge. You can see the steep cliffs in the background, so you can see the spittles in the background. And then there's this wide flat Rocky platform at the base where the cliff has retreated and left this behind. Question three, where is the land steepest? You have to choose from A and B. B is shown in the first diagram. Here, those brown lines which are called contours are very close together. Contour lines are every five metres. And that shows that the land there is very steep. So we've got cliffs at B. At location A, which is the bottom image, the lines are further apart, which means that the land is flatter. If you have no contour lines, it means that the land would be completely flat. Question four, you can see a shingle beach below Black Ven, right in the top right corner. You've got the sandy beach, which was yellow, but there are dots on it and that represents the shingle. Next we had to look at a six figure grid reference for a church with a tower. Church with a tower, we can see it here, has a black square with a cross on top because that square represents a tower. Over here, we have a church with a spire. So the circle represents a spire. If you didn't have a spire or a tower, we can see here that it could just be shown with a black cross to represent a place of worship. To do a grid reference, we need to go along the corridor first. So 34. We're then looking at how many many squares along that large square it would be. And it's about four, it's just before halfway. So along the corridor would give us 34, four. When we climb the stairs, we're going to climb up to 92. We want to know how many little squares along. So it's significantly below halfway. So we would go for 92, two. Remember if you were struggling with any of these questions, you can pause the video, and spend more time looking at the answers. Another question that they love putting us to the test with in exams, is which way is the photographer facing? We've got an OS map, and remember North is always at the top of the OS map, but I've put a compass arrow there to help us out. We've also been given a photo, and we've been given a photo of Lyme Regis Harbour. And that curve structure is The Cobb. So to work out how to do this, you're looking for something that is recognisable on the map. Our caption tells us this is Lyme Regis Harbour, and we can see where that's on the map. I'm then looking for shapes to help me work out direction. And on the map, you can see that the Cobb has that curved shape. And that clearly shows on the picture here. We've also got another jetty where people are walking out, and that is shown here. So it goes from the beach out towards the curve of The Cobb. The photographer stood on the hillside, and he's looking out over the Harbour. And he's looking to where the Cobb curves round with a bit sticking out. If we then place that arrow onto the map, we can see he stood on the hillside, he's looking over to the curve of The Cobb, and he's got the jetty to his left hand side. Let's take the arrow, let's put it on the compass arrow, and we can see that in this photo, the photographer was facing South East. It's a really tricky skill. So the only way you can get better at it, is to practise it. So now we've got a different photo. Which way is the photographer facing now? I'd like you to pause and tackle this question yourself. Look for shapes, look for buildings you can identify on both. You can do it. Right, I'm checking you've written down your answer. You've got to give it a go. It's important to be brave. The photographer is facing East. Let's try and work out why. The first thing I notice on this picture, is this building on this pier or jetty. The caption tells us it's The Cobb. On the map, here is the building. So black line with a cream inside. We've got the curve of The Cobb. If we put that on the map, there's that curve there. So the photographer is standing just before the curve. And he's looking directly to the middle of the building. If I transfer that arrow over, say from the start of the curve, looking at the building, we can see the direction East. How did you get all? It is super tricky, but if we keep practising , we'll get there. We're sticking with OS map but this time we're looking at land use. Can you take 10 seconds now, pause the video. I would like you to talk about, what the land use is like at A. See if you'd come up with three or four things, and what the land use is like at B. What did you have written down? At A, the land use is residential and commercial, it's a town centre. So the land use is going to be very high value. There are lots of blue symbols at A, and those are tourist attractions. The star signify attractions, we've got several museums, we've got an information centre, we've got an aquarium, and below it, we've got boat trips. These blue symbols are tourist attractions so therefore they would bring in lots of money to the area. We've also got a large wide beach so we would suggest that that is used for tourism. Land use at B is much quieter. There is a wide beach still, but the car parks are further away, so we would predict that less towards visit this area. Behind the beach are steep cliffs. There aren't any buildings. So the land value is going to be much lower at B. Why is managed retreat not an option in Lyme Regis? Managed retreat is where they remove all existing defences and let the land behind flood. Just take five seconds, see if you can come up with two reasons. Hopefully you've noticed then that the wide beach would be really popular for tourism. It brings in income. We can see that the area behind is densely populated with lots of buildings so they will have a high value in. And there isn't empty or low value land, which gives space for flooding. So managed retreat is not an option here. The value of the coast is too high. We've got a few ideas why Lyme Regis needs coastal management, but let's just summarise these. Lyme Regis is a popular tourist destination. We already know that this industry has a value of around 800 million pounds for the whole of Dorset. So Lyme Regis needs that protection to maintain its tourist industry. Lyme Regis is built on a layer of clay and sand, which is slippery and this is sat on top of a layer of solid limestone. The clays and sand on top often slip on top of the limestone. The coastline is eroding more rapidly than any other in Europe, with powerful waves coming from the Southwest. The cliffs are eroded at the base, which makes them even more unstable. Many properties have already been damaged due to erosion and mass movement. For example, in 2013, nine beach were destroyed due to a landslide. The original sea wall has been breached many times. So in storms, waves have been able to go over the sea wall, and damage the land behind. Right, tricky one now, so I've given you four statements about Lyme Regis, but all of them are incorrect. I would like you now to pause the video and to rewrite these sentences, but you have to change one element in each of them to make these statements correct. Good luck, pause now. Statement one, Lyme Regis is located on England's South coastline. Statement two, Lyme Regis is built on unstable cliffs. Statement three, Lyme Regis' coast is eroding more rapidly than any other in Europe. Statement four, Lyme Regis' original sea wall had been breached many times. So pause if you missed any of those, make sure you've got them all down correctly. We know why Lyme Regis needed management, but let's just have a brief introduction into what management was used. I'm going to quickly recap the four hard engineering methods. These are all in a previous video if you'd like to look at them in more depth. We had Groynes, Sea walls, Gabions, and Rock armour. Our soft strategies were Dune regeneration, Reprofiling, and Beach nourishment. Lyme Regis has used a mixture of hard and soft engineering types. On the screen, I've got photos of three strategies that Lyme Regis has used. Pause the video now and see if you can name the management strategies below. Strategy A was Rock armour. B was beach nourishment. That Digger there is adding sediment to the beach, and C is a sea wall. And here, if you look carefully at that picture, they're actually building the sea wall behind the old sea wall. And you can see it's much taller. This picture shows you what they've done at Lyme Regis. And in the next video, we're going to have a look at all of the things in depth. They have put rock armour down near The Cobb. They've used rock armour on the North wall. They've added stone groins and used beach nourishment. They've also added rock armour and stone groins around the River Lym. To the East of the River Lym they have nailed, drained, and piled those cliffs to make them more stable. Time for your main task. Using the photo and your own knowledge, explain why Lyme Regis needs coastal management. So this question I would like you to give me two reasons. I would like those explanations to be developed, and you must mention the photo for one of them. Pause the video now, take four minutes to answer this question. You will be amazing, good luck. Let's check your writing. I'm going to start with the photo. The photo shows that Lyme Regis has a wide sandy beach, which has lots of tourists on it. This suggests that coastal management is important to maintain the beach, and the income from tourism. Another reason is that the coastline is eroding more rapidly than any other in Europe and so there are many shops and houses in the town, at risk of being damaged from coastal flooding. It's just two examples there. You could have used different examples, if it's not here, don't worry. What I do want you to check though, is that you've got that connective to make sure your answer is explained. This suggests that therefore, meaning that. Let's say it brings us to the end of today's lesson. We've had a look at why coastal management is vital in Lyme Regis. We learned that Lyme Regis is built on unstable cliffs and being battered by strong winds, and destructive ways from the Southwest. That leaves it vulnerable to erosion and mass movement. But while Lyme Regis may suffer from destructive waves, I think our time today has been very constructive and we've learned lots. But remember management is vital. So you protect your learning by making sure you go onto the next page, and complete that quiz and revisit everything that we've done. Thanks so much for your time today, take care, and I look forward to you joining me soon as we move on to have a look at what Lyme Regis has done, and what the effects of that management have been. Have a great day, everyone.
