How do rivers transport their load?
Solution – minerals are dissolved in the water and carried along in solution. Suspension – fine light material is carried along in the water. Saltation – small pebbles and stones are bounced along the river bed. Traction – large boulders and rocks are rolled along the river bed.
What is river energy?
Abstract. River current energy conversion systems (RCECS) are electromechanical energy converters that convert kinetic energy of river water into other usable forms of energy.

Why do rivers Bend?
Because slow-moving water can’t carry as much weight as fast-moving water, loose dirt and rocks build up on that side, making it more shallow. Eventually, the build-up creates new land and a new curve in the river’s watercourse.
What is the main work of rivers in the lower course?
Answer. The volume of water in a river is at its greatest in the lower course. This is due to the contribution of water from tributaries. The river channel is deep and wide and the land around the river is flat.
Which is the main work of a river in its upper course?
erosionIn the upper course, the main work of the river is erosion.
Why do we need rivers?
Humans use rivers for irrigation in agriculture, for drinking water, for transportation, to produce electricity through hydroelectric dams, and for leisure activities like swimming and boating. Each of these uses can affect the health of a river and its surrounding ecosystems.
How do rivers get water?
Most rivers begin life as a tiny stream running down a mountain slope. They are fed by melting snow and ice, or by rainwater running off the land. The water follows cracks and folds in the land as it flows downhill. Small streams meet and join together, growing larger and larger until the flow can be …
