Classifying rivers - three stages of river development river characteristics - sediment transport - river velocity - terminology notice how the erosional and depositional features change according to the positions of outside and inside curves the straight section of the river (e-f) is a basic u-shaped. This video explains the stages that a river goes through from its source to its mouth the diagram is hand drawn so that you are able to understand the process and also replicate it in. The congo river, the 9th longest river on the planet, is 2, 920 miles it is also the deepest river on the planet, and it is over 700 feet deep it is the second longest river in africa (the longest being river nile) the congo's source is at the highlands of north-east of zambia, it flows into the atlantic ocean at. Rivers - long profile the long profile of a river is a way of displaying the channel slope of a river along its entire course therefore, it shows how a river loses height with increasing distance towards the sea.
River morphological reports 10 introduction india, with a vast area of 329 million hectare, has diverse geographic and which deals with the change of river plan form and cross sections due to sedimentation and erosion in this field, dynamics of flow and sediment transport are the principal. Changing channel characteristics channel cross profiles the channel cross profile (or section) is a view of the river bed and banks from one side to the other at any one point on it course as a river flows from its source to its mouth, a number of typical changes take place in the channel morhology. River features found in the lower course this is the part of the river nearest the sea here, the gradient is even gentler the river flows even more slowly and the volume of water is greater deposition is much more important than erosion in this part of the river some features usually found in this section are.
A river walks into a bar and the bartender asks, why the long profile a level/gcse geography revision for river characteristics and the long profile skip navigation. Streams slowly change their characteristics over time in response to changes in elevation, gradient, volume of water, and available the following illustration shows 4 different river profiles which river profile best represents the cross-section of a stages of a river. The long profile the long profile of a river shows changes in the height (altitude) of the course of a river from its source to its mouth a long profile is usually concave and the slope becomes more gentle towards the mouth of the river. River energy fluctuations along its course leads to a dynamic environment whereby the form of the river can change season by season many landforms are formed in the middle course as a direct consequence of the relative energy balance changing, resulting in both erosion and deposition.
A multiple part lesson on the long profile of a river main activity involves students constructing their own long profile from data, images and key terms using the base provided graphic organiser included can be used to consolidate le. Rivers are constantly changing their course, meandering through time and space, forming new features and erasing old ones meander amplitudes get wider because the soil erosion carrying capacity increases with the width of the river. A river is a large, natural stream of flowing water rivers are found on every continent and on nearly every kind of land some flow all year round others flow seasonally or during wet years a river may be only kilometers long, or it may span much of a continent.
Rivers are linear systems which show a gradient of characters along their length ideally the longitudinal profile of a river is concave with a steep upper portion near the source, giving way to reaches of progressively less gradient as the mouth is approached other features of the river are. Erosional features interlocking spurs - as the river cuts its deep v-shaped valley in its upper course, it follows the path of the easies trock to erode thus it tends to wind its way along, leaving the more resistant areas of rock as interlocking spurs // meanders - meanders occur in the mid course and lower course of the river, where it is beginning to cut laterally as it gets closer to. Whitewater paddling is obviously an exciting yet dangerous activity the main concerns lie in the water and the water features themselves it is therefore crucial that the whitewater kayaker, canoeist, and rafter know not only the terminology for whitewater river features but also how to identify them as well as be able to communicate them to other whitewater paddlers. Valley profiles long profile the long profile of a river illustrates the changes in altitude of the course of the river from its source, along the entire length of its channel, to the river mouth in general, the long profile is smoothly concave, with the gradient being steeper in the upper course and becoming progressively gentler towards the.
The long profile is a graph of a river that marks the change in altitude from the upper course to its lower course all along its course, the river uses energy to carry out erosion , transport and deposition of sediment. The long profile of a river shows changes in the height (altitude) of the course of a river from its source to its mouth water balance the balance between inputs and outputs is known as the water balance or budget. The nile river, one of the longest river systems in the world, begins with six cataracts that flow into a narrow valley-river section, then spreads out into the marshy nile delta near the mediterranean sea. A river begins life high in the hills or mountains in a cold region, a river may be created by melting snow or a glacier slower, less steep, and change course more gradually the features they form are bigger and more substantial: wider lakes, wandering s-shaped bends called meanders, and deeper, broader cuts in the landscape called valleys.
A river changes shape as it flows from its source to its mouth the shape of the long river profile and the cross river profile changes. A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river in some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Home geography question: geography controlled assessment - an investigation into changes in the long profile of the river holford aim: to investigate the river holford’s key characteristics, such as the long profile of the river channel, how this impacts upon changes in both processes and the river’s physical features themselves. Another word for the slope of a river, measured in feet / mile or m / km best illustrated by the river's longitudinal profile tidal dominated type of river delta (eg mississippi delta) in which the river exerts a strong control on the delta's growth and shape.
