Economic benefits of rivers and lakes are: Provide water for irrigation. Provide water for drinking. Help to develop hydel power. Assists in fishing. Help to develop hydel power. Aids in tourism and recreation.
Rivers offer various economic benefits like generating hydroelectric power, they are used for internal navigation, they provide fish for human consumption, rivers are used for navigation purposes, transporting goods, and irrigation purposes. Lakes are an important destination for tourism.
The middle course of a river has more energy and volume then in the upper course.
noun. The channel through which a river flows.
The main function of the river in the middle course is transportation of sediments . It becomes a little slow and increases in volume . The major landforms formed by the river in this stage are flood plains , meanders , ox-bow lakes and braided rivers .
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.
Characteristics of a river Characteristics Upper course River channel The river has a very narrow channel and a shallow one too. Force/strength and speed of the water The water is slow, as there is low force is it Amount of water There is little water as it only comes from the source of the river.
Rivers flow downhill, not necessarily south. Gravity is the ultimate determining force in terms of water flow. Water will flow downhill from the highest point to the lowest point using the path of least resistance.
Weathering is a process in which rocks get disintegrated into smaller particles or get decomposed at or near the surface of the Earth. For example, biological weathering. Denudation is a long term process in which the wearing and tearing of the surface of the Earth takes place.
The action of running water which include streams, rivers, and rainfall, have constantly shape the surface of the surface of earth through erosion and depositional processes. River (or running water) is one of the most active agent of land form development.
