What is erosion? |
In earth science, erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location. |
|
|
What is weathering? |
Weathering is any of the chemical or mechanical processes by which rocks exposed to the weather undergo chemical decomposition and physical disintegration, such as the freeze dry method. |
|
|
What is longshore drift? |
Continual swash and backwash transports material sideways along the coast. This movement of material is called longshore drift and occurs in a zigzag. |
|
|
How are spits formed? |
Spits are formed where the prevailing wind blows at an angle to the coastline, resulting in longshore drift. An example of a spit is Spurn Head, found along the Holderness coast in Humberside. |

|
What is an SMP? |
A Shoreline Management Plan (SMP) is a large-scale report, assessing the risks associated with coastal processes. |
|
|
How do SMPs work? |
They aim to help reduce these risks to people, property and the historic and natural environment. The main objective of a SMP is to identify sustainable long term policies for the coast |

|
What is hard engineering? |
Hard engineering options tend to be expensive, short-term options. They may also have a high impact on the landscape or environment and be unsustainable. |
|
|
Name some hard engineering methods. |
Sea wall, Groynes and Rock armour/Rip-Rap |
|
|
What is soft engineering? |
Soft engineering options are often less expensive than hard engineering options. They are usually more long-term and sustainable, with less impact on the environment. |
