A landform at the mouth/source of a river. Formed by the deposition of sediments carried and dropped off by a river, sometimes resulting in a triangular shape. Where is a delta formed? When river flow hits standing water (ocean/lake) the river expands its width.

Established dunes may appear to be permanent fixtures in the landscape, but in fact they are a landscape of constantly shifting sand. Wind gusting in different directions will blow sand from the dune either further inland or back onto the beach.

A delta is a land form comprised of sediments found at the mouth of the river. A delta can only form when river channels carry sediments into another body of water. This is because the sediment land mass developed at mouth of this river formed a triangular shape that looks like the upper case Greek letter delta.

Top 8 Most Fertile River Delta of India

• Ganges Delta. Ganges Delta also known as Sunderbans Delta or Ganges Brahmaputra Delta in the Bengal region of the Indian subcontinent.
• Godavari River Delta.
• Kaveri River Delta.
• Mahnadi River Delta.
• Krishna River Delta.
• Bhitarkanika Delta.
• Kuruvadweep Delta.
• Cooum Delta.

Narmada

Tapti River

Narmada and Tapi along with other small rivers originating from the Western Ghats and falling in the Arabian Sea form estuaries in place of deltas. This is due to the fact that these rivers, especially Narmada and Tapi, flow through hard rocks and are not able to form distributaries before they enter the sea.

The Narmada River flows east to west, and is 815.2 miles long. It originates in a small reservoir called Narmada Kund at a fairly high elevation, and empties into the Gulf of Khambhat. The high source elevation gives the water a lot of force, as the flow of the water is gravity driven.

Delta’s are so fertile because sand from different lands brought by water. Delta is a landform that forms from deposition of sediment carried by a river as the flow leaves it’s mouth and enters slower-moving or stagnant water.

Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land. A river moves more slowly as it nears its mouth, or end.

Originating high on the Tibetan Plateau, the Indus River flows more than 3,000km before emptying into the Arabian Sea. It is here where the fan-shaped delta forms an extensive system of swamps, mudflats, creeks, estuaries, marshes and mangroves forests.

Indus Delta. The climate is arid tropical marine. The mean monthly summer rainfall is 75 mm and winter rainfall less than 5 mm. The mean daily temperature is between 34 °C and 40 °C in summer and between 19 °C and 20 °C in winter.

Paleodelta, an important landform encompassing an area of~50 km 2 , lay landward of the modern Periyar River mouth (Narayana et al., 2001) , which suggests that the River Periyar was once a major river system carrying large volume of sediments.

STARVED of fresh water and no longer able to withstand the encroaching Arabian Sea, the Indus is dying a slow death. The destruction of the Indus delta is a direct consequence of the dams and barrages that have been built higher up on the river.

Major estuaries occur in the Bay of Bengal. Many estuaries are locations of some of the major seaports. Most of India’s major estuaries occur on the east coast.

This fan-shaped delta supports the seventh largest mangrove forest system of the world in vast tidal mud floodplains. But it is shrinking rapidly owing to decreasing river flows to the delta, land subsidence, a rise in sea level, low rainfall because of climate change, and surface and subsurface seawater intrusion.

Arabian Sea

We believe in the free flow of information The Indus is one of Asia’s mightiest rivers. From its source in the northwestern foothills of the Himalayas, it flows through the Indian state of Jammu & Kashmir and along the length of Pakistan to the Arabian Sea.

The arid and semi arid conditions prevailing over the Balochistan Plateau and the southern part of the Indus Plain is not favorable to support plant growth and results in thorny bushes and scrub. In Indus and Hub deltas the deposition of alluvium in the salt water has encouraged the growth of mangrove vegetation.

The Indus River plain is a vast expanse of fertile land, covering about 200,000 square miles (518,000 square km), with a gentle slope from the Himalayan piedmont in the north to the Arabian Sea in the south.

The Indus delta begins near Thatta(Sindh) and the river Indus by distributing itself into a number of branches joins with the water of Arabian sea. The Indus plain of our country are very fertile and all the cultivation is done here due to the ample amount of water.

Answer. Explanation: Agriculture is the second-largest sector of the Pakistani economy, accounting for approximately 21 per cent of GDP. It is highly dependent upon the Indus River system as farmland is mainly irrigated by water from the Indus River and its tributaries.
