The holderness coast is located in the east coast of England and is a natural landscape that is slowly eroding away. As well as erosion, some deposition is also taking place and the long shore drift that is occurring on the coastline's beaches has resulted in a "Spit" (a depositional feature), called "Spurn Head". This feature is well known and many people go to see this landform as it is a very long and thin strip of land which people like to walk across and view this beautiful landscape. Look for yourself below.
Holderness is a lowland region of England that lies between the chalk hills of the Wolds and the North Sea. It is part of the East Riding of Yorkshire.
The Holderness Coast is one of Europe's fastest eroding Coastlines. The average annual rate of erosion is around 2 metres per year. The main reason for this is because the bedrock is made up of till. This material was deposited by glaciers around 12,000 years ago.
The Holderness Coastline is made up of soft boulder clays (tills) left after the retreat of the Devensian ice sheets about 12 000 years ago. They can be seen on the coast, being rapidly eroded by the sea. To look at, they are a mass of brown clay containing pieces of rock (erratics) brought here by the glaciers from Scandinavia, Scotland, the Lake District and Northeast England. These soft, recent deposits sit on a platform of chalk which slopes away gently to the east.
1.The soft Boulder Clay cliffs become saturated with rain water and lose their strength.
2.The cliff is too steep and fails either as a block of material or as a slurry slide
3.Cliff failure reduces the angle and prevents further erosion but …
4.Large waves from the North East remove the debris in longshore drift to the South and the cliff oversteepens, rain falls and the cycle begins again.
Situated approximately 3km south of Hornsea lies the village of Mappleton. Supporting approximately 50 properties, the village has been subject to intense erosion at a rate of 2.0m per year, resulting in the access road being only 50m from the cliff edge at its closest point.
Mappleton lies upon unconsolidated till (boulder clay). This material was deposited by glaciers during the last ice age 12,000 years ago.
Mappleton is an excellent case study of an attempt at coastal management. In 1991 two rock groynes and a rock revetment made from huge blocks of Scandinavian rock were built.
As a consequence a substantial beach accumulated between the groynes halting erosion (picture 1 below). However, further south the rate of erosion has increased significantly (picture 2 below). This is because material which is being carried south is not being replaced (it is trapped within the groynes). Therefore there is no beach to protect the cliffs. Even during a neap tide ( a tide which is 30% less than the average tidal range) the sea reaches the base of the soft cliffs and erosion occurs.
1 Cliffs to the north. Sea defenses mean that the beach has grown and the cliffs are stable (look at the grass growing!)
2 Cliffs to the south. The sea defenses don't protect this area and the land is retreating rapidly.
Aldbrough is a small settlement to the south of Mappleton. Where Mappleton had substantial sea defenses built, Aldbrough has none. The cliffs here are rapidly eroding.
Some residents think that the sea defenses at Mappleton has made things worse. Why would they think this?
This settlement attracts tourists, so substantial sea defenses have been constructed to maintain the beach.
How many sea defenses can you see in this picture?
The old settlement of Kilnsea has now been completely lost. Sea defenses were built here in the early 1900s to protect the Godwin Battery - a defensive gun emplacement and the rail-head for a light railway to further military installations on Spurn point. The sea defenses are now crumbling and erosion is progressing rapidly.
The area known as Spurn forms the southern extremity of the Holderness coast and includes the unique feature of Spurn Head, a sand and shingle spit 5.5km long, reaching across the mouth of the Humber. Spurn is made up of the material which has been transported along the Holderness Coast. This includes sand, sediment and shingle.
1.The material eroded from the Holderness cliffs is swept southwards.
2.North easterly waves move the coarser sands and gravel down towards the mouth of the Humber
3.The finer sands and clays are swept offshore and continue southwards towards the Wash.
4.Spurn Head 'hangs like a rudder' for six kilometres off the end of Holderness, built by the sands and gravels eroded from the cliffs and transported south by longshore drift
5.In the past Spurn Head seems to have grown and been washed away in a regular cycle, slowly moving towards the east to keep pace with the erosion of the Holderness cliffs.
6.For over 100 years the position of Spurn has been fixed by artificial sea defenses. These defenses are now falling into disrepair and the sea is starting to erode parts of the peninsula once again.
Spurn Head changes position. Most of the spit has flexible road surfaces, which are like mats that can be picked up and moved following major storms.
There is plenty of evidence of this movement. Former railway tracks that were built to move building materials along Spurn (for the building of Bull Fort in the Humber Estuary) now appear to lead into the sea.
The end of Spurn is fairly stable. This is due to it's size and the presence of deep rooted plants.
The rest of Spurn erodes and moves constantly. There are some groynes to protect it, but these are very old now.
The Humber estuary is very busy with large ships. It is one of the most dangerous estuaries in Europe, so pilots guide boats in and out. Their base is on Spurn for quick access to sea. The pilots do not live on Spurn.

The Holderness Coast is approximately 20-30 miles east of Hull, depending on the specific location along the coast.
boulder clay and chalk
The Holderness Coast in the UK is primarily composed of soft sedimentary rocks such as clay, sand, and gravel. These rocks are easily eroded by the sea, causing the coastline to retreat at a rapid rate.
we can no longer use their mums
It's roughly 5 feet a year
Spurn Point and the area around Aldbrough are areas in the Holderness Coast that are particularly exposed to deposition due to the prevailing northeast winds and the longshore drift process. These areas experience significant erosion, leading to the deposition of sediment along their shores.
Holderness, located on the east coast of England, is famous for its dramatic chalk cliffs and coastal erosion. The area is known for its picturesque landscapes, including the charming villages and natural beauty of the Yorkshire Wolds. Additionally, Holderness is recognized for its archaeological sites, such as the remains of ancient settlements and artifacts. The region also attracts visitors for its outdoor activities, including walking and birdwatching along the coast.

Yes it was invaded by siamese cats and is now called ferball coastline. hope this helps.
George Holderness was born in 1913.
