It starts in the Plynlimon Hills, 740m above sea level. Annual Precipitation is 2500mm rainfall a year (very wet). The river flows in a broad semi-circle starting northeast and swinging round clockwise to southeast where it flows out into the Bristol Channel.

    General Coastal Notes + Landforms! 1 Types of Coastlines: Type Description Primary Coast which is essentially in the same condition when sea level stabilized Coastline after the last ice age, “younger”. They are created by erosion (the wearing away of soil or rock), deposition (the buildup of sediment or sand) or tectonic activity (changes in the structure of the rock and soil because of earthquakes). River deltas are an example of a primary coast. They form where a river deposits soil and other material as it enters the sea. Secondary Coastline shaped primarily by marine forces or marine organisms, and wave Coastline energy is the main agent shaping the coastline. Emergent Emergent coastlines are stretches along the coast that have been exposed by Coastline the sea due to a relative fall in sea levels. Submergent Submergent coastlines are stretches along the coast that have been Coastline inundated by the sea due to a relative rise in sea levels. Concordant A coastline consisting of bands of rock, which run parallel to the coast. Coastline Discordant A discordant coastline occurs where bands of differing rock type run Coastline perpendicular to the coast. Factors affecting Wave Energy: Factor: Description Wind Speed Wind speed will in turn affect wind energy, which determines the size of the waves. Higher wind speed = Higher wind energy = Larger waves Fetch Fetch is the distance of the ocean which the wind blows over, Longer distance = Larger waves Wind How long the wind has blown in the same direction (steady winds at slower Duration

  • Topic: Coastal Systems 3.1.3.2 Geomorphological & Coastal Processes
    Topic: Coastal Systems 3.1.3.2 Geomorphological & coastal processes What you need to know How weathering and mass movement affects the coastline How erosion, transportation and deposition affect the coastline Introduction: Coastlines differ according to their orientation and geology. Coastlines which protrude out into the sea and are formed from less resistant sedimentary deposits are more likely to be modified by a range of coastal processes than a less exposed hard rock cliff face. Where wave energy is strong, erosion and transportation is more likely to take place and conversely, where wave energy is weaker, deposition will occur. As well as wave energy, other geomorphological processes can modify the coastline. Chemical, mechanical and biological weathering loosen rocks, in advance of their removal by waves and mass movement also provides loose material. Geomorphological processes: These include marine, atmospheric and terrestrial processes. Subaerial weathering: Mechanical weathering: There are two main types of mechanical weathering which occur at the coast. • Freeze-thaw weathering occurs when the daytime temperature is different than the night-time temperature either side of freezing point on rock faces. During the day, water enters cracks in the rock and at night when the temperature drops the water expands as it freezes. The increase in the volume of ice exerts pressure on fissures in the rock and weakens it internally. During the day, when the temperature rises again, the ice melts. The process reoccurs repeatedly until the rock breaks apart. The material is then loose to fall onto the shore. • The other type of mechanical weathering is exfoliation. This occurs when the daytime and night-time temperatures are distinctively different on dry rock.

Due to the different nature of the rock erosion occurs at different rates. Less resistant rock (e.g. boulder clay) erodes more rapidly than less resistant rock (e.g. chalk). What is a wave cut platform? A wave-cut platform is a wide, gently sloping surface found at the base of the cliff and extends into the sea. How is a wave cut platform formed?
