Spread the pebbles out in the swash zone, and place a marker further up the beach to show the start point for the pebbles. The main ways that the sea erodes the coast are: This modal land use and its associated score can then be used in the flood risk calculation. Choosing a fieldwork location Choose a stretch of coast with some variation. Bi-polar analysis Questionnaires Cost-benefit analysis.
What happens to the sediment which has been eroded from the sand dunes? Wave Cut Notch and Wave Cut Platform Wave cut platforms are made in a similar ways to waterfalls and gorges rivers topic. Read more at the Institution of Civil Engineers website. To clarify what we learnt last lesson, watch from minutes on the coasts to the right. Each sample should be placed in a sealed plastic bag and accurately labelled. The area of land between high tide and low tide. Evaluating the impact and severity of flooding behind coastal defences Severity of coastal flooding can be determined by considering the properties that would be affected by flooding, especially their economic value or worth if damaged.
Responses are limited to positions on a scale. Rocks been thrown into the cliffs by waves and breaking off bits of the cliff. How it works 2.
Geography- Whistable Coast Project – GCSE Geography – Marked by
Beaches cane be divided into backshore, offshore and foreshore. Wave Cut Notch and Wave Cut Platform Wave cut platforms are made in a similar ways to waterfalls and gorges rivers topic.
The harder rock forms a headland. Click the diagram to make it bigger.
The main ways that the sea erodes the coast are: Use a tape measure to find the height of beach material on either side of a groyne. What is the land use along the coast at x? Annotate all the main features using the description above. If you star in the photo, you will gain extra credit.
Geography Coursework- Coasts
Cosats material is higher on one side of the groyne. The distance between two crests or two troughs. Are these hard defences sustainable? Bays are usually more sheltered so there is less erosive power, meaning you often find beaches in bays.
Please rank the following statements from 1 most important to 6 least important Answers: Hydraulic pressure will be the main type of erosion. Rip-rap volume and weight measurements Rip-rap or rock armour is often used as a technique of coastal defence. If they find a crack or a joint they will start attacking it.
The a-axis is the longest axis The b-axis is the widest axis at right angles to the a-axis. Use a stone card to measure the minimum radius of curvature. Is coastal squeeze happening at x? Each reading is taken from from break of slope to break of slope.
Bays and Headlands Bays and headlands are formed in a very similar way to rapids rivers topic. Beach profiles Beach profiles use distance and angle measurements to help you investigate the shape of the beach. Use statements with a balance of positive and negative. RSA videos are those that are manipulated by speeding up, slowing down, time lapse and over dubbed with your voice. Maps and aerial tcse Historical maps and photographs Wind and wave data. The measurement technique used depends on the size of the sediments.
Overtime the crack may turn into a cave.
You can record your thoughts on the worksheet beneath. High resolution maps are available that show individual buildings and height above sea level. After 20 minutes find as many pebbles as you can, and measure how far each has moved from the start point.
Bi-polar analysis Questionnaires Cost-benefit analysis. Caves, Arches, Stacks and Stumps Caves, arches, stacks and stumps are usually found on headlands, where wave refraction is causing erosion on three sides.
