Long shore Drift My intentions are to carry out an investigation, which will determine the affects of longshore drift

Extracts from this document...

Introduction

Long shore Drift The managed section of the beach will be affected more than the unmanaged section from longshore drift and thus cause coastal erosion. My intentions are to carry out an investigation, which will determine the affects of longshore drift. The investigation itself will be broken into two different parts, these being the affect of longshore drift on a managed section, which has groynes to trap sediment, thus forming a protective beach. I will assess these areas before continuing with any data collection, when we had discovered a managed. I understand that longshore drift is an important coastal process as it is related to the transportation and deposition of sediment and how either erosion occurs by abrasion or attrition or hydraulic action. ...read more.

Middle

It is also a good source Advantages? * It is simple to achieve but it can account for explanation of my ideas. * This method needs a basic requirement of equipment. Disadvantages? * The sketch must be accurate otherwise the examiner will not understand what I am explaining. * Photos obtained from computer may be inaccurate Where? In areas with great importance to parts of coastline under study Questionnaires Equipment? Questionnaire, eleven relevant questions and pen. Method? * Ask people around the vercinity the questions. * Record the answers on the database as part of a group collection. Why is it necessary? It acquires the opinions of the public to how effective management techniques and how problems can be improved. ...read more.

Conclusion

* It is an easy method to accomplish. Disadvantages? * It is time consuming. * If there is little longshore drift, then the movement of the ball is limited. Beach Profile Equipment? Ranging Poles, clinometer, measuring tape and record sheet Method? * Place poles on ground so that they do not penetrate. * Apply clinometer to section on pole and measure angle that the clinometer records. * Record results for each 2m interval on a longitudinal plain. Why is it necessary? By carrying out this investigation, I can see to what extent sediment build up is occurring and link my conclusions to longshore drift. Advantages? * It shows how the beach differentiates in slow gradient. Disadvantages? * The method is very time consuming * The angle of negative or positive elevation may contain an error of judgment. Where? Both sides of the groyne in a managed section ...read more.

    This is important for this hypothesis as how the beach is in different locations explains whether or not there actually is variation in the coastal protection. The pebble analysis would show which type of pebbles and sediments were deposited in which location of the Brighton beach.

    with the availability of more nutrients. Both shores are susceptible to the conditions described above but with varying degrees. In the exposed rocky shore, the environment is much harsher. The limpets experience accelerated wind speed and the effects of wave action would be more prominent. This is due to the length of fetch, which is large and the aspect, usually towards the prevailing winds.

    Mass movement is faster in wet weather. Debris soaks up rainwater, becoming heavier, so the pull of gravity is more. Also, if water cannot pass through the rock below the debris, it flows down the rock surface helping movement of the debris.

    Patella vulgata is a resilient species and can tolerate long periods of emersion and consequently wide variations in temperature. Stronger, adult species are not affected by temperature changes as Fretter & Graham (1994) showed that adults could survive temperatures of up to 42 �C and a 60% water loss.
