Watershed : Source 1. Source The 3 major watersheds which direct and control the flow of surface water in India are: The Great Himalayan watershed with its important Karakoram branch In Central India, the watershed is formed by Vindhyas, Satpura and Maikala ranges.
The Western Ghats. What happens in one part of the basin or watershed eg flood, drought etc. The data about land and water characteristics is measurable and comparable. River Profile River Rejuvenation River Rejuvenation refers to a significant enhancement in the erosive power of the rivers. It can happen because of the following reasons: Fall in the sea level lowering of base level of erosion Dynamic upliftment of the land For a given load, if there is a considerable increase in the volume of water.
For a given volume of water, if there is a considerable decrease in the load. The main differences are: The regimes of Himalayan Rivers are monsoonal as well as glacial. This is because the Himalayan Rivers are perennial as they are fed by glaciers through snow melt and also receive rainfall water during rainy season. The river Ganga has its minimum flow during the January-June period, maximum flow is attained either in August or in September followed by a gradual steady fall afterwards.
The regimes of most of the peninsular rivers, on the other hand, are monsoonal as they are fed by rainfall alone e. The fall in October is as spectacular as the rise in August as the monsoon season ends.
Basins are vital to human existence, since they provide clean water for drinking; water for growing food; and water to nourish plant life, which provides the oxygen people breathe. Over a long period of time, an oceanic basin can be created by the spreading of the seafloor and the movement of tectonic plates.
A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or more rarely another river that cannot carry away the supplied sediment.
It is formed by riverborne sediment that is deposited at the edge of a standing water, in most cases an ocean, but some times a lake. The morphology and sedimentary sequences of a delta depend on the discharge regime, the sediment load of the river, and the relative magnitudes of tides, waves, and currents Delta : A delta is a triangular piece of alluvial low land formed at the mouth of the. It is formed due to deposition by the river at its lower course. Estuary : Those rivers which do not form deltas, form estuaries.
Four examples of deltas in India are : i Ganga-Brahmaputra delta. The definition of a delta is a triangle-shaped deposit of sand, clay or silt at the mouth of a river. An example of a delta is where the Nile River drains into the Mediterranean Sea. Deltas form when a river flows into a body of standing water, such as a sea or lake, and deposits large quantities of sediment.
Delta is found in the old stage of a river. It is the triangular shaped landform made up of alluvial deposition in the mouth of the river. It is named after the fourth Greek alphabet called delta.
Example, The Ganges Bhramaputra delta is the largest delta in the world. Begin typing your search term above and press enter to search. The water from each of these distributaries flows into the ocean for which it is named. There are two leading methods geographers and potamologist s people who study rivers use to classify tributaries. The first method lists a river's tributaries starting with those closest to the source , or headwater s, of the river. The Rhine, one of the longest rivers in Europe, has its source in the Alps and its mouth in the North Sea.
The second method lists a river's tributaries by their flow. Small streams are identified with low numbers, while larger tributaries have higher numbers. The Tshuapa and Kasai Rivers are both left-bank tributaries of the Congo River, the deepest river in the world. The Tshuapa is a smaller river, and has a lower tributary ranking, than the Kasai. Human activity in tributaries is often responsible for polluting the mainstem. The river carries all the runoff and pollution from all its tributaries.
Rivers with tributaries that drain land that is not used for agriculture or development are usually less polluted than rivers with tributaries in agricultural or urban area s. Development, not size, determines the pollution of rivers. The Amazon River, with the largest drainage basin in the world, is much cleaner than the Hudson River, for instance. The Ganges has more than a dozen tributaries, including the Alakananda and Bhagirathi, above. Photograph by Asis Chatterjee, MyShot.

Examples of Tributaries in California Although tributaries feed into larger water bodies, they themselves are often of substantial size and frequently named as rivers.
