Footpath Erosion I am trying to find out how footpath erosion on Pen Y Fan which is a national park, compares to footpath erosion on Cock Marsh which is in a village and is not in a national park. The question is 'how does footpath erosion on Pen Y Fan compare to footpath erosion on Cock Marsh'. Backround information on Pen Y Fan and the Brecon Beacons The Brecon Beacons is a lived and worked in national park. The area within the national park covers 519 square miles. Nearly half of
prove whether this hypothesis is true or not. Introduction I am going to Lulworth Cove to investigate the effect the Cove have on the area, specifically I will be looking at footpath erosion and the general environmental quality of different sites within the area. As a coastal area it is also subject to erosion by the sea so we will be looking at how the beach is affected by wave or if it would remain preserved in the future without any need for management. Lulworth Cove is situated

collect the information there I'm going to be using a number of resources. I will be using a camera to take pictures of the tourist facilities and the costal defences. Also I will do a number of sketches of the landscape to show the damage done by erosion and weathering. I am going to do a land use survey of the shops on Highcliff high street to make a list of the shops that are there. I will then use the Internet, textbooks and various handouts to research other general information about the
s owned by the National Trust, a charity protecting certain area and is run with membership funding. Hypothesis: We would use all of the evidence given above. We have used OS maps with a 20 year gap and it shows that there is considerable erosion from west to east This shows that it is eroded at one end more which is a sign of long shore drift. I also believe that the pebbles would have got smaller and rounder due to abrasion and attrition. Method and Data collection: Firstly I
Canada-timber beach 2) USA-tin can beach A beach may be a store in a bay or a mobile stream along the coast. Four Sources of Beach Material; · 1) Material eroded from headlands dependant on the rock type. Easily eroded bolder clay resistant to erosion is granite. * 2) Sediment moved up onto the beach from the offshore zone material is washed up from the seabed. * 3) Large rivers carrying material from inland to the sea mainly silt and clay. * 4) Material cycled from one beach along the
run-off caused by erosion, and trying to raise better yields. Although it may seem as if there is no answer, many farmers are turning to no-till as the solution. Some farmers stand against no-till, saying it keeps the ground too cold for too long in the spring, or that it will not allow them to get their crops up, but much research proves these beliefs wrong. No-till is an advantage over conventional-till for three main reasons: conserves moisture in the soil, reduces erosion by wind and rain, and
Costal erosion, especially on barrier islands, is a major concern throughout the world. The issue represents a serious concern for many vulnerable coastlines throughout the coastal regions of the world. This issue must be studied for root causes so it can, if at all possible, be brought under some semblance of control before it is too late. The cost of ignoring this issue would be catastrophic to both communities on the beach and the marine life that depend on the coastal areas for their very
the building. Originally the church was 3kms away from the sea but as the cliff was eroded it eventually became next to the see. There was a danger the cliff under the Twin Towers and therefore the Twin Towers themselves would be destroyed by erosion. To stop this happening many coastal defences and different types of management have been erected. The initial try at coastal management was in 1809. Wooden and ragstone blocks were place at the foot of the Twin Towers to protect them. The apron
Slope Movement There are certain threshold conditions that can be applied to slopes- if a threshold condition is exceeded then the slope moves. There are many types of movement, and the following factors can affect movement: a) Rockfall On a cliff face material will fall as it becomes released by weathering, and often accumulates as scree at the cliff foot. The angle of the scree is just below the threshold angle for movement and is called the angle of rest. A particle of weathered
broken down by weather and erosion. Sediment formation begins when igneous or metamorphic rocks are exposed to the earth's surface. The long process starts with erosion. The first thing to happen to a igneous or metamorphic rock when exposed to the earth's surface is weathering. All rocks regardless of type are susceptible to weathering. Weathering is a part of erosion and consists of anything or any process that breaks down rocks. Some examples, called agents of erosion, are water, wind, ice, and
Louisiana’s growing ecotourism business (http://www.lacoast.gov/new/About/Default.aspx?utm_source=twitterfeed&utm_medium=twitter). The effects of erosion and loss of marsh land in the Southern United States has devastating consequences to all of these benefits, both local and national. The loss of land can mostly be attributed to subsidence, erosion, and severe weather events. The USGS reports that a total of 118 square miles of land has been transformed to new water areas in a 9,742 square mile
one-foot penetration into the beach is violated. The scraped sand is pushed to the back of the beach, usually into a low sand ridge. Bulldozing sand is not a good thing for beaches. For one, taking sand from any part of the beach is a form of beach erosion, pure and simple. For another, it kills the organisms in the beach – the mole crabs, the Coquina clams, and all the microscopic organisms that live between the sand grains. For days after bulldozing, seagulls have an unexpected bonanza: swooping and
Structure of Laterites and Lateritic Soils Soil structure is the size, shape and arrangement of mineral grains which form the soil mass. Soil structure is a major characteristic that influences all other engineering properties of the soil. Due to the processes of laterization, lateritic soils have attained distinct structural characteristics. It is an over-simplification to identify all temperate zone soils with dispersed structure and lateritic soils with concretionary structure (Remillon, 1967)
An Unwanted Visitor Hot summer days and cold wet winters are usually the norm in the golden state. Needless to say the norm can often be changed. As is the case for the periodic droughts that come and devastate California’s peaceful climate. While these droughts are definitely not an unfamiliar event to residents of California, their effects do vary on the majorly agricultural state. When the weather phenomenon does act upon the golden state, it seems California is always on the defensive
Deforestation Resulting from European Shipbuilding Historical texts have documented the countless technologies, ideas, diseases, plants and animals the European ships delivered around the world during the Age of Exploration. However, these texts fail to include one key cargo item: deforestation. European shipbuilding triggered an epidemic of forest depletion that gradually spread to the lands they encountered. Beginning in the early fourteenth century, wood fueled the increased production of
The Change of a River From Its Source to Its Mouth Main Aim: To find out in which ways a river changes from its source to its mouth. We traveled to the west coast of Wales to find out how a river changes from its source to its mouth. We were situated in the small rural village of Tal-y-bont, which was near the town of Aberystwyth. The river that we decided to test out with our hypothesis and find out our aim on was the river Einion. The river Einion is a tributary to the river Dovey
It is this soft sand and clay which is easily eroded by the action of waves, as the ocean slowly claims back the region it used to occupy. There are several factors which have resulted in this region experiencing one of the fastest rates of erosion. One already mentioned is the material which is being eroded, or the geology of the land. The boulder clay deposited 20,000 years ago as a result of the last retreating ice age is a soft rock of little resistance. Although it also cannot quite
Reaches 0-4km · Processes The main process in this section is erosion, in the form of: attrition, corrasion, hydraulic action and corrosion. Attrition is when the boulders collide with each other, breaking up into smaller pieces. Corrasion is when the ,material carried in suspension rubs against bank of river. Hydraulic action is the rivers force dislodging particles and finally corrosion is when acids dissolve rock. Erosion occurs because at this point the river is above its graded profile
Introduction Within this paper, the differences between a summer and winter beach will be explained thoroughly, and the sand samples taken from the back shore portion of Huntington Beach, located in South Carolina, will be used as proof of these differences. The sand samples taken at both summer and winter periods will be defined and analyzed in great detail, as will the beach area itself. Once having read this paper, the general background information on the type of sand collected, specifically
