Is a place in a river where water spills suddenly downward?

A waterfall is a place in a river where water spills suddenly downward. Smaller or less steep waterfalls may be called cascades. Cascades often fall over a number of short rock walls. The action of flowing river water is one of the most common causes of waterfalls.

What name is given to the bottom of the river?

A stream bed or streambed is the channel bottom of a stream or river, the physical confine of the normal water flow.

What is a place along a stream where water drops?

Waterfall. A place in a stream where water falls straight down.

What do waterfalls flow into?

A waterfall is a river or other body of water’s steep fall over a rocky ledge into a plunge pool below. Waterfalls are also called cascades. Often, waterfalls form as streams flow from soft rock to hard rock.

What is the name for the volume of water flowing along a river?

Flow rate. Volumetric flow rate, also known as discharge, volume flow rate, and rate of water flow, is the volume of water which passes through a given cross-section of the river channel per unit time.

What is the crest of a waterfall?

brink
Crest. The top of the waterfall. More specifically, the top edge from which water falls. Also referred to as the brink.

What is the head of a river called?

headwaters
The place where a river begins is called its source. River sources are also called headwaters. Rivers often get their water from many tributaries, or smaller streams, that join together. The tributary that started the farthest distance from the river’s end would be considered the source, or headwaters.

What is it called when a river mixes with the sea?

An estuary is a section of river where fresh water and sea-water mix together. Tides cause water levels in estuaries to rise and fall. Geologists call river deposits alluvium. Alluvium is coloured yellow on the superficial geology map of the UK. Can you find where a river started its journey?

What do you call a river that flows back and forth?

Rivers flowing over gently sloping ground begin to curve back and forth across the landscape. These are called meandering rivers. Over time rivers can cut through bedrock.

What is it called when water rises above the top?

If such a confined aquifer is tapped by a well, water will rise above the top of the aquifer and may even flow from the well onto the land surface, as in a spring. Water confined in this way is said to be under artesian pressure, and the aquifer is called an artesian aquifer.

Where does the water in a river come from?

The water in rivers comes from many different sources. Rivers can begin in lakes or as springs that bubble up from underground. Other rivers start as rain or melting snow and ice high up in the mountains. Most rivers flow quickly in the steeply sloping sections near their source.
