Headland. This means the waves no longer erode the northern side of the headland and material‚ such as Awhitu sand stone and volcanic rock are no longer eroded and deposited in to the sea at Muriwai. Because of the lack of erosion‚ the amount of sediment transported northward‚ up the beach‚ is also affected. This human modification and its impact on processes can be summed up in the following diagrams. (complete appropriate diagrams) * Human modification 2: Construction of Revetment (boulders

S11048002. Rivers‚ as they flow to the sea they carry with them sediments. Sediment transportation is dominant in the upland flows where the velocity or speed of the river flow is very fast and the slope is of a steep type. As the sediments are carried along to the lowland‚ the water velocity is reduced and so there is a reduction in the speed of the river flow and also the slope is of a gentle sloping thus causing the sediments to be deposited on the lower parts of a river. The Rewa River is one

What are watersheds? An area or ridge of land that separates waters flowing to different rivers‚ basins‚ or seas. 2. What does a watershed consist of? Watershed consists of the few underground springs and precipitation runoff from the land. 3. Why are watersheds

comprised of sediments (sand‚ clay‚ silt‚ gravel) found at the mouth of the river‚ where the river enters a standing body of water (lake‚ pond‚ reservoir‚ or ocean). Herodotus‚ a Greek Historian‚ considered by many as the “Father of History”‚ studied this great geologic feature. He is credited with coining the term “delta” for this is type of landform because of its triangular shape reminded him of the Greek letter Δ (delta). Delta Formation Delta forms when river carrying sediment reaches a

a deep canyon or gorge will take shape. In areas of high precipitation‚ heavy rain erodes the valley walls and the sediment is transported downstream. The river valley then widens but differs in depth compared to dry climates. Formation and key features of 4 stages of river development: Youth stage: A young river is shaped as a deep V-shaped valley. It moves quickly‚ and transports material further downstream. The rapid moving water and high erosion rate doesn’t allow deposition to occur. Features

particles being deposited in the river bed as energy levels drop. The middle stage features mainly lateral erosion this is due to the rivers channel slightly flattening out as it goes down. Attrition of larger particles in this stage means that sediment particle size decreases from source to mouth. More material carried in the river’s suspension as particle sizes decreases due to a higher level of erosion. Some larger particles are moved by saltation. This therefore means particles such as sand

Public Transport is dreadful! They are always either late‚ delayed‚ having engineering work or on strike! More that half of the population in London have complained about the public transport in their area but the thing is there is nothing we can do about it. So much money is spent on the public transport‚ but then why is it there is so many flaws to it and its always running late? Public Transport is used by thousands of people each day‚ that would explain why every time I get on a bus or train
