Describe and explain the concept of a sediment cell and how it can be used in coastal management A sediment cell is a length of coastline in which interruptions to the movement of sand or shingle along the beaches or near shore sea bed do not significantly affect beaches in the adjacent lengths of coastline. In addition to this‚ it can also be referred to a sediment that is moved along the coast by long shore drift appears to form part of a circular cell which leads to it eventually returning up

The main impacts on the wetlands in the area are associated with historic land use. They include drainage channels and furrows that modify wetland hydrology and reduce their functionality. Eight wetlands in the area were identified for rehabilitation intervention. Concrete and gabion structures are used to stabilize erosion and help to maintain wetland health. The wetland

than others‚ making waves stronger and more powerful. I think wind is the most important factor. 3. I think the steepest beach will be Hurlstone because it’s the end of the beach where pebbles will be at their smallest and roundest due to erosion. 4. I think the gentlest beach will be gore point because it’s at the beginning of the beach where the pebbles will be at their largest and more angular. The study took place at Porlock bay in Somerset‚ Southwest England (see maps on

is a place where water flows over a vertical drop in the course of a stream or river. Landforms in upland regions are dominantly created by erosion processes‚ where land is worn away. Generally‚ the volume and discharge of rivers in upland regions tends to be low‚ and the river uses much of it’s energy in overcoming friction. The erosion direction here is vertical‚ or straight down into the bed of the river. This has the effect of destabilising the slopes on either side of the river‚ creating

They may ask themselves questions like what’s next? How can I reach my full potential? How can I give back to the world? Some people may go off to college‚ some will get jobs they love‚ some will get jobs they hate‚ and still others will join programs that give back like the Army‚ Peace Corps‚ or USAID. USAID is

sea. Erosion occurs via rain‚ weathering by wind and frost. Its impact is often seen in soil creep‚ slumping and landslides. | Corrosion | When waves approach the coastline they are carrying material such as sand‚ shingle‚ pebbles and boulders. Abrasion occurs when this material is hurled against cliffs as waves hit them‚ wearing the cliff away. | Human activity | Much building and recreation occurs at the coast‚ and this increases pressure on cliff tops‚ making them more liable to erosion and

Biological weathering is where the processes of living organisms‚ animals and plants‚ help to weather rocks to aid in the process of erosion. Examples of Biological weathering are tree roots growing and expanding through cracks in the rock‚ especially those which hold a lot of water within them‚ and the decomposition of dead animals and plants produces acidic by-products that slowly corrode the rock. These processes can take thousands of years to begin to see any real results. Biological weathering

10 REASONS WHY TREE PLANTING IS IMPORTANT 1. Trees Produce Oxygen Let’s face it; we could not exist as we do if there were no trees. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year. What many people don’t realize is the forest also acts as a giant filter that cleans the air we breath. 2. Trees Clean the Soil The term phytoremediation is a fancy word for the absorption of dangerous chemicals and other pollutants that have entered the soil. Trees can either

also be keen in protecting the environment. They would learn from Singapore to prevent undesired disasters. Nature reserves could also save lives. Roots of trees make soil stable and prevent soil erosion and soil leaching from happening. Thanks to nature reserves‚ there are only a few cases of soil erosion happening in Singapore. On the other hand‚ by setting aside land for nature reserves‚ Singapore is unable to continue her development smoothly. Since land in Singapore is limited‚ she should make

Soil erosion: Soil erosion can be defined as the destruction of the top layer of the soil as a result of natural or human activities. Soil erosion refers to the carrying away of soil. Soil erosion is also serious type of environmental degradation. It affects crop production‚ pollutes water resources and causes many other direct and indirect problems
