Describe and explain how river processes

River systems, fluvial processes and landscapes, floodplains, and river control strategies are important to human populations as demands for limited water resources increase stream-related processes are called fluvial (from the latin word fluvius = river) . Description of the hydrologic cycle the sciences of meteorology and oceanography describe parts of a series of global physical processes involving water that are . River processes and pressures describe and explain the river drainage basin as a system and how it links to the hydrological cycle. Describe and explain how river processes change along a river’s long profile essay activity: describe and explain how river processes change along a river’s long profile (15 marks) upper - erosion - vertical - weak erosion but strong velocity in the upper stage of the river’s long profile, there is mainly vertical erosion and by abrasion. Describe and explain the process of knickpoint migration knickpoint migration is the upstream shift in location of a knickpoint due to erosion knickpoints form where stream flows over a resistant layer of rock.

How the river thames has dominated london life from ancient times to the present day processes, and sedimentary hazen audel and rob nelson explain rivers the . Find animations showing processes of river erosion, transport and deposition. Meanders a meander is a winding curve or bend in a river meanders are the result of both erosional and depositional processes they are typical of the middle and lower course of a river this is because vertical erosion is replaced by a sideways form of erosion called lateral erosion, plus deposition within the floodplain.

The four types, or processes, by which a river erodes are hydraulic action, abrasion or corrasion, attrition and corrosion each process affects the river in different ways hydraulic action is where the force of the river water pushes into holes in the riverbank and causes the riverbank to collapse . Landforms of fluvial erosion and deposition processes such as abrasion and hydraulic action a plunge pool forms at the base the river can become choked . River processes: erosion, transportation and deposition & the hjulström curve there are three main types of processes that occur in a river. Describe and explain the main features of a river meander draw a cross section of a river meander and label it explain how meanders migrate downstream . Describe and explain- the formation of landforms along a river passage this results in the river cutting rapidly downwards, a process called vertical .

This page covers river systems, processes shaping rivers, upper and lower course landforms, flooding and flood management river processes and pressures - gcse geography gcse geography. Possibly it's to do with the tranquility of a river in countryside or in cities, the sight of water has an instantly calming effect processes, and sedimentary . Explain why (4 marks) (ii) describe and explain the development of meanders (15 marks) 3- questions from the current as: (i) (based on photo) describe these potholes and explain their formation (7) (ii) (based on figure of meander and flood plain): describe the role of flooding in the formation of river landforms (6) this question could also be a 15 mark question. How and why do river valleys change downstream this is the reduction in the size of fragments and particles within a river due to the processes describe above . Explain why river landforms are created, and why they are found in that course again, refer to your landforms booklet you should be able to talk about the different processes (erosion, transportation, deposition) and why they act differently along the course of the river.

describe and explain how river processes change along the long profile of a river a river changes shape as it flows from its source (where a river starts) to its mouth (where a river flows into a sea or lake). River processes as a river flows along its course it undertakes 3 main processes which together help to shape the river channel and the surrounding valley these processes are erosion, transport and deposition. Before looking at specific river landforms it is important to look at how the river channel itself changes downstream weathering processes may also aid this . Natural processes of ground-water and surface-water interaction of ground water and surface water in river valleys is affected by the interchange of local and .

With a diagram it is easier to explain and you give yourself a better chance of scoring full markson the other hand, the question may say, with the aid of a diagram explain the formation of - (for example, a waterfall). describe and explain how river processes change along the long profile of a river a river changes shape as it flows from its source (where a river starts) to its mouth (where a river flows into a sea or lake) the shape of the long profile (a slice through the river from source to mouth) shows how the rivers gradient, height, energy and load changes due to erosion processes such as abrasion . The water cycle is all about storing water and moving water on, in, and above the earth although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe.

There are two types of question you might be asked about river processes one is to explain the processes of the river the other is to describe how the processes make landforms. Mass movements can be very dangerous because they can happen very quickly and involve entire hillsides sometimes a mass movement will dam a river a lake will form behind the dam.

River processes by alex jackson last updated on august 2, 2014 rivers have a lot of energy and because they have energy, they do stuff in the case of a river . What is a river system every river is part of a larger system—a watershed, which is the land drained by a river and its tributaries rivers are large natural streams of water flowing in channels and emptying into larger bodies of water. - describe and explain the processes of weathering and erosion that affect coastal environments ocr (b): - understand how physical processes of weathering can change coastlines and river basins.
