A Study of the Changes in River Processes
This is a study of the changes in river processes along the long profile of a river. To study this we will use a sample river. The river the study will be based on Loughton Brook, which is a river situated in Epping Forest in Essex and is also a tributary of the river Thames. A journey will be made to the river and measurements will be made at three different sites. The measurements that were taken will be studied so conclusions can be made about the changes to characteristics of a river with distance downstream.
Aims and Hypotheses
The overall aim of this study is to investigate the changes in river characteristics downstream along Loughton Brook.

Also the shape of the three diagrams shows that the left side of the river is deeper than the right side. This may be due to erosion of the left side and deposition on the right side, which suggests that the flow of the river is faster on the left hand side than the right.
Graph 4 is the river cross-section diagram for Site 1. It shows that the river cannel is 3.5m wide and at its deepest point it is 0.23m deep. The shape of the riverbed can be seen using this graph. It shows that the left hand side measurement of the river is deeper at 0.23m than the right hand side measurement at 0.085m. This difference of 0.145m may be due to the erosion and deposition on the riverbed.
Graph 5, the diagram for Site 2, shows that the river channel is 3.4m wide which is 0.1m narrower than at Site 1 and also the river is 0.22m deep at the deepest point which is 0.01m shallower than the measurement for Site 1. The left side is deeper than the right side like it is in Site 1. The left side measurement is 0.22m deep and the right side measurement is 0.09m deep. Again the difference of 0.13m may be due to erosion and deposition.
Graph6 is the cross-section at Site 2. The diagram shows that

Sedimentary rock from the older Silurian Period is further from the river banks (Geological map of Victoria, 1973). Mudstone, inter-bedded shale and greywacke depositions indicate the Maribyrnong River may have previously taken a different shape, and younger sediments have replaced the older sediments in more recent geological periods.
In truth, the river is the border between the gothic space, the Other, and normal space in the novella. For example, in the beginning of the story, when Danillo and Katherine were travelling home on the Dnieper, they witnessed a rising on the side of the Other. “A withered corpse rose slowly from it [one of the graves in a graveyard]. one could see he was suffering terrible agonies” as he begged for air (Gogol 18). Things that should not happen, that should not be possible, happen on the other side of the Dneiper because that is the gothic space.
Follow The River by James Alexander Thom is about Mary Ingles gruesome but yet courageous tale of her remarkable 1,000 mile journey home after she had escaped form the captivity of the Shawnee Indians. Through Mary Ingles hard work and determination she proved that all obstacles big and small can be overcome.
● Frozen River is based on the life of working class families that live in mobile homes in Massena, New York who are trying to survive, solve struggles and meet their needs. One of the families consists of a single mother name Ray trying to raise her 2 children on her own. Ray works part time at a retail store as a clerk. She has worked there for almost 2 years hoping to become a manager. With the disappearance of her husband she struggles paying her bills, providing food for her children, and not being able to finance the purchase of a new mobile home.
The Colorado RIver is best known for being the principal river of the southern United States and Mexico, but it soon could lose that title. Running about 1,500 miles long, the river is a vital source of water for agricultural and urban areas in the southern desert lands of North America. However over the past decade or so, the river has begun to deteriorate. There are many causes and solutions to the deterioration of the Colorado River.
The Mississippi River is one of the world 's extraordinary rivers. It is the longest in the United States, more than twenty-three hundred miles in length, as it structures the outskirts of ten states, just about bisecting the mainland (Currie,2003, 8). This waterway has a long history also, and it has touched the lives of numerous individuals. The Mississippi is said to start at Lake Itasca in Minnesota. In 1832, pilgrim Henry Schoolcraft named this lake, not after any neighborhood Indian name, but rather from the Latin words for "genuine head" which are veritas caput abbreviated to "Itasca" (Currie, 2003, 4). In any case, much sooner than its source was named it was a navigational waterway. The Indians who initially lived on the banks of the stream were known as the Mississippians. From 800 to 1500, these people groups utilized the waterway for exchange. They dug out
Can you imagine having to leave everything you have ever known to live in a country on the verge of war? Lesley Shelby, the main character in One More River by Lynn Reid Banks, knows exactly how it feels. This Jewish Canadian girl has to emigrate to Israel with her family. Through the determination and courage of one person we see how challenges, complications, and differences of the world are overcome.
To measure the cross-section you will need to find the width of the river first. To do this, you will need to stretch a tape measure from one bank to the other at a 90° from the course of the river. Measure from where the dry banks touch the water. Once you have found the width of the river, your next job is to find the depth of the the river (across the width). The more detail you want, the more readings you will need to take. An example of a good interval would be 50 cm but it also depends on the width of the river. Leave the tape measure where it was when you measured the width to ensure you a straight line which can help you to measure the depth. It will also help you measure the distance between each
A useful way to study a river is to look at its long profile and its
Describe and explain the changes that occur in a river channel as it moves from source to mouth.
The Features and Processes of a River Along Its Profile Introduction ------------ Along the path of a river, from source to mouth, the river shows many different features and is affected by several different processes. These processes are going to be described and explained in the course of this essay and diagrams will be used to back-up and justify my ideas. A river can be simply divided into an upland or lowland river environment.
River catchment management has three aims which determine if the management plans are of good quality or not. These aims are to keep the river flowing, to maintain good water quality and to sustain biodiversity. In Mtunzini, the sources of the Amanzimnyama and Siyaya Rivers have been impacted on by plantations of Eucalyptus also known as Blue Gums and Sugar cane respectively. Before Confluence, both rivers travel through an area of rehabilitated dune forest which was part of Ian Garland’s catchment management strategies to improve the quality if the rivers. The Siyaya Estuary was damaged by floods in 2012 and this has caused the estuary mouth to close and deteriorated the water quality.
...d be affected by floodplains. The study of peak discharge of a given area can help humans better predict the chance of a flood. These predictions will help people determine how to protect communities from future floods and also decide whether or not an area is a safe place to develop new communities. However, sediments are deposited by the river during floods. Flooding gives a rich supply of sediment-born nutrients to the soil, so areas around rivers with wide floodplains are usually used for farming.
In addition, the total volume of water discharged during a flood tends to be larger for urban streams than for rural streams. For example, stream flow in Mercer Creek, an urban stream in western Washington, increases earlier and more rapidly, has a higher peak discharge and volume during the storm on February 1, 2000, and decreases more rapidly than in Newaukum Creek, a nearby rural stream. As with any comparison between streams, the differences in stream flow cannot be attributed solely to landuse, but may also reflect differences in geology, topography, basin size and shape, and storm patterns (Konrad and Booth, 2002).
