background Upper course The source of the river is normally found in an area of high ground. The river usually flows through a steep V-shaped valley. Most of the erosion that occurs in the upper course is vertical and as the river bed is eroded lower the valley becomes steeper. The river is narrow with a shallow channel. As discharge is calculated by measuring the cross sectional area of the channel multiplied by the velocity‚ the discharge is small. The river is mainly slow flowing as most of its energy

When a river runs over alternating layers of hard and soft rock‚ rapids and waterfalls may form Waterfalls A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Landforms in upland regions are dominantly created by erosion processes‚ where land is worn away. Generally‚ the volume and discharge of rivers in upland regions tends to be low‚ and the river uses much of it’s energy in overcoming friction

that submerges land which is normally dry. Flooding may occur as an overflow of water from water bodies‚ such as a river or lake‚ in which the water overtops or breaks levees‚ resulting in some of that water escaping its usual boundaries‚ or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. Types of floods * Slow-onset floods - flooding of river systems in the northern pastoral areas of South Australia can spread for thousands of square kilometres and last

significant and unexpected events‚ for instance dam breakages. Heavy rainfalls are one of the major causes of floods. The level of water in rivers or lakes rises due to heavy rainfalls. When the level of water rises above the rive banks or dams‚ the water starts overflowing‚ which causes floods. The water overflows to the areas adjoining to the rivers‚ lakes or dams‚ causing floods or deluge. The flood water causes havoc and great destruction in the areas where it flows. Floods occur more in the

what extent do you agree that river landforms can be classified as either erosional or depositional? Many different landforms are made by either deposition or erosion and there are some cases where they can be classified as both. Erosional landforms are caused by erosion which is the breaking down and transportation of particles from one area to another. Depositional landforms are made when particles are deposited somewhere else. In my opinion I think that river landforms can be classified as
