Assumption: That wave energy changes and longshore drift occurs along the beach Methodology: Annotated sketches showing evidence of erosion and management. Measure pebble long axes, randomly selected using random numbers and a quadrat, or with a marked pebble dropped at random.

After being dropped, the pebble it touches at its marked end should be selected for measurement. Pebble size is related to both wave energy and longshore drift direction.

Hypothesis 4: That beach profiles will change along beach 18 related to changes in wave energy and longshore drift. Profiles to be recorded using an abney level, ranging pole, calibrated pole and measuring tape. To ascertain minimum beach width and the degree of sand accumulation.

Assumption: (a) that longshore drift occurs and that some sections of the beach are more prone to sediment accumulation than others; (b) that some sections of the beach are subjected to high energy (destructive) rather than low energy (constructive) waves. Analysis of the degree of sand accumulation should point to the nature of the processes operating on the beach, particularly dominant wave direction and longshore drift.

For example at 0 metres the sizes of the stones were 25; 24; 28; 21; 18; 10; 15; 13; 14 and 25 millimetres. In comparison at 35 metres the stones were much larger as they were 45; 35; 75; 40; 51; 49; 35; 40; 50 and 32 millimetres.

The reason why, was the fact that material was sorted along the beach profile by the wave energy.Hypothesis 5: That sandy beach profiles in the main town will reflect the processes operating on the shingle beach Assumption: (a) that longshore drift occurs and that some sections of the beach are more prone to erosion than others; (b) some sections of beach may be aligned with a longer fetch and more prone to erosion from high energy waves.Method: Measurement of three profiles on each of the sandy beaches as per Hypothesis 3.For instance, large stones will be at the top of the beach profile as they were larger and when they were dumped at the top by the swash, the backwash won't have the sufficient amount of energy to bring them down.The swash will be able to put them at the top because the top of the wave will not be affected by the friction which occurs between the sea bed and the waves.The visit is a one-day outing to Brighton, a coastal region situated on the South Coast, this is shown in Figure 1.Figure 1: Location of Brighton in England Figure 2: Location of Brighton in Europe Brighton, a small coastline town, depends on the incoming of 'tourism' to boost its reputation.By doing a hand-drawn graph I can determine how the pebble analysis varies along the shoreline in the different sites.30-34 Graph showing the Beach profile results on all four sites I have chosen this specific graph because it will show me how as the distance increases what happens to the angle. This shows to me where we performed the questionnaire as it was one of the Hypotheses. This shows to me how most of the cars come from, and this diagram gives a clear explanation of this.The significance of tourism on Brighton's economy (the level of reliance Brighton has for its tourist system) Several investigations were taken place to establish the aims, listed above.Coastal Management Hypothesis:- Brighton has its ups and downs, even though it may be booming in popularity it suffers from serious coastal changes. Middle This could be because of the fact that waves were constantly bashing the beach and the stones were constantly being moved.

    Coastal fieldwork methods – Where to start Having run several coastal field trips now I thought I would compile a run down of all the techniques I have used with a bit of a review of their success, what groups they are good for, the likely results, how to present the data and how to go about doing them.…

    Page 25 of 59 Mouth- This is the river Holford’s mouth at Kilve beach. Although this was not a site and we did not sample here, we can tell that the clasts are smooth and that there is a downward gradient as the water goes into the Bristol Channel. The water percolates through the limestone and came back up on the beach into the Bristol Channel.…

    I will visit five sites along the Beach – Burton Bradstock, West Bexington, Abbotsbury, Chesil Visitor Centre and Chiswell – this is aiming at systematic as I am trying to look along the whole length of the beach – however I am limited by access in some areas of the beach. At each location, I will measure beach profiles – using stratified…

    Beach Profiles. Shingle beaches typically have a steep gradient over 10˚ because the waves easily flow through the coarse, porous surface of the beach, decreasing the effect of backwash erosion and increasing the formation of sediment into a steep sloping back.…
