what is the upper course of a river

Full Answer

What are the characteristics of the upper course of a river?

In the upper course of a river gradients are steep and river channels are narrow. When a river runs over alternating layers of hard and soft rock, rapids and waterfalls may form. Waterfalls commonly form where water rushes down steep hillsides in upland areas and quickly erodes the rocks. What is the upper course of the river Tees like?

The “course of the river” simply refers to the specific path that a river follows as it crosses the land. This is usually a sinuous (curvy) channel that tends to get wider as the river makes its way to its final destination. Simply so, what is upper course of a river?

What is the lower course of a river called?

Lower Course. The Lower Course is where the river flows gently because of its gentle slope, and also it looks like a lake habitat. This winding lowland parts of a river contain muddy, slightly warmer water, which flows more slowly. Plants grow in the bed of the river and at its edges.

What happens in the middle course of a river?

The middle course is where the river starts to slow down. It gets wider, and travels in winding loops. There is a lot of lateral erosion, deposition and transportation. The middle course can take up most of the river. In the middle course, you might find: The lower course is the last course of a river.

What is the upper course of a river called?

Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.

What is middle course of river?

The middle course of a river is found on gently sloping land, and is typically identified by its meandering path - the sweeping side to side curves. The middle course has two main features - meanders and ox-bow lakes.

In the upper course, the main work of the river is erosion.

Where is the lower course of a river?

In the lower course, the river has a high volume and a large discharge. The river channel is now deep and wide and the landscape around it is flat. However, as a river reaches the end of its journey, energy levels are low and deposition takes place.

What is the lower course of river called?

Lower course of a river Energy in the river is at its lowest and deposition occurs. . Deltas are often found at the mouth of large rivers. An example is the Nile Delta. Deltas are formed when a river deposits material faster than the sea can erode it.

What is the definition of upper course?

What Is the Upper Class? The term upper class refers to a group of individuals who occupy the highest place and status in society. These people are considered the wealthiest, lying above the working and middle class in the social hierarchy.

What is the course of a river?

There are three parts of a river, the upper course (The start of the river), the middle course (The middle part of the river) and the lower course (The end of the river). All rivers start at the source. This is usually up in the hilly ground. This means that there is a steep gradient which causes fast flow.

What is the primary course of a river?

If we look into the whole length of a river we will notice that it has three definite courses: 1. The Upper or Mountain Course 2. The Middle or Plain Course 3. The Lower or Deltaic Course.

Why the river flows swiftly in upper course?

Answer. (i) Erosion is the dominant activity of a river in its upper course because at this stage, the river flows swiftly, for the gradients are steep. Under the impact of rush of water and the load the river carries, erosion action is swift and effective.

What are the features of a middle course river?

Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas. As the river moves through the upper course, it cuts downwards. The gradient here is steep and the river channel is narrow. Vertical erosion in this highland part of the ...

What are the landforms of rivers?

River landforms can be divided into upper, middle and lower course features. These include steep V-shaped valleys, oxbow lakes and flood plains, respectively. Part of. Geography. Rivers and water.

What is vertical erosion?

Vertical erosion in this highland part of the river helps to create steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. As the river erodes the landscape in the upper course, it winds and bends to avoid areas of hard rock. This creates interlocking spurs, which look a bit like the interlocking parts of a zip.

What are the characteristics of the upper course of a river?

Typical features of the upper course of a river: Cauldron Snout on the River Tees. Vertical erosion has led to the formation of this landform.

How do rapids form on the River Tees?

Rapids on the River Tees. Rapids form when there is vertical bedding which is when alternate bands of hard and soft rock cross the channel. Differential erosion will occur as the soft rock is more easily eroded than hard rock.

How do gorges form?

Gorge. A gorge can be formed as a waterfall retreats up a valley. This happens when a river flows over a band of hard rock that lies over the top of the softer, less resistant rock. The river erodes the softer rock faster, through hydraulic action and abrasion. This erosion leads to the undercutting of the softer rock.

Where do waterfalls form?

Waterfalls. Waterfalls commonly form where water rushes down steep hillsides in upland areas. They are typical of the upper valley but can be found in the rivers lower courses. The height and number of waterfalls along a stream or river depend upon the type of rocks that are being eroded by the water.

What is a convex slope?

convex slopes. project from alternate sides of the valley. separated by a narrow valley floor which is mainly taken up by the river channel. sometimes covered in woodland. may have scree slopes.

What are the lower course features of a river?

Each is defined by particular variations of features such as discharge speed, the width and depth of the river bed, ...

Which part of the river has the most landscape features?

The upper course of a river is where the river begins its path toward the sea. This part of the river arguably has the most landscape features, and biggest range of physical features.

Why are V-shaped valleys so difficult to find?

They can be difficult to locate because of their tiny size. V-Shaped Valleys - These are the landforms that carry the river down from the source to the main body of the river. Their V-shape form means the river simply follows the point at the bottom, before it becomes big and strong enough to carve its own path.

What are the parts of a river?

PARTS OF A RIVER. Rivers are split up into three parts: the upper course, the middle course, and the lower course. The upper course is closest to the source of a river. The land is usually high and mountainous, and the river has a steep gradient with fast-flowing water.

What is the gradient of a river?
