The beach is a really awe-inspiring place. Not only is there an amazing array of flora and fauna, you can also watch science happening right before your eyes.
When you are at Ground Zero, you will be on top of one of many groynes in the area, reaching far out into the sea. This groyne looks like a long concrete wall.
The first question is: can you describe two other types of groyne, perhaps ones you have seen elsewhere in Hastings and Bexhill?
The second question is: which natural effect are the groynes designed to stop? Please give a brief description.
The third question is: can you see any evidence of the groyne fulfilling its purpose? Please explain.
The fourth question is: can you think of any possible negative effects of groynes?
Optional: I would love to see a picture of you or your GPS at Ground Zero, either with the magnificent cliffs or the sea in the background!
Don't worry if your English is not so good, just a few words for each answer are fine. Ihr könnts gerne auch auf Deutsch schreiben!
Congratulations to Bellas Pack for FTF!
N.B. juliadream has brought to my attention that this structure actually seems to be what is known as a mole, as opposed to a groyne... Have a read here and see what you think! https://en.wikipedia.org/wiki/Mole_%28architecture%29
N.B. #2 deepdiggingmole suggested that the structure is a breakwater: "The Department for Environment, Food and Rural Affairs (DEFRA) says the developed 5km frontage of Hastings and St Leonards is protected by a system of seawalls and groynes which help to retain the shingle beaches. [...] A breakwater is a coastal structure (usually a rock and rubble mound structure) projecting into the sea that shelters vessels from waves and currents, prevents siltation of a navigation channel, protects a shore area. It is the latter that these appear to be the function - protecting the seashore." I'd be interested to hear your opinions :)
