Enquiry question for coasts physical fieldwork

How effective are coastal management strategies in Swanage Bay

Describe one method we used to collect data (longshore drift)

Stand 1m away from where swash stops Throw an apple into the sea, 1 metre back from where waves break Start a timer Wait for the apple to wash up Measure the distance between where the apple ends up and where you are standing

Cons of longshore drift collection method

It is hard to repeat as you don't know exactly how far to throw it Apple is not the same as sediment - it is bigger, it floats

Pros of longshore drift collection method

• Eco friendly

• Gives clear numerical data

Sampling technique for longshore drift method

Opportunistic

Sample size for longshore drift method

Describe one method we used to collect data (groyne profile)

Start at the groyne closest to the sea wall  Measure the height on the post on the north side using a metre stick keep going down the groyne until you have measured 10 posts then repeat and measure the same 10 posts on the south side work out the mean gives clay comparison between North and S

Cons of groyne profile method

measurements are not exact as it depends on where you placing me to stick each time only collects 10 posts

Pros of groyne profile method

• gives clear comparison between North and South

• Easy and quick

Sampling technique for groyne profile

Systematic

Why is Swanage Bay an appropriate location for coastal fieldwork

It has groynes, sea wall, and beach renourishment Easy to access as it is close to London Sites of coastal management are near each other

Identify a hazard in your geographical fieldwork and how it may be reduced

Sea Don't go in the sea beyond ankle height Do beach and groyne profile at low tide so you don't lose access to beach

Why is a bar chart an appropriate way to present groyne profile data

You can easily see difference in N and S by using different coloured bars

Assess the effectiveness of a line graph to present beach profile data

• It is effective as you can clearly see trends

• Could be improved by doing more repeats

Advantage of secondary research

Over a long period of time, so a wider range of data

Disadvantage of secondary research

Out of date Don't know when it was recorded
