INDIA-DRAINAGE SYSTEM &BASINS

{*Meaning- The river system of an area is called drainage and  total area that contributes water to a single drainage system is known as a drainage basin. }

India is a country where more than 4000 big and small rivers flow. As per the origin of these rivers, Indian rivers are divided into two categories.
1. Himalayan Rivers
2. Peninsular Rivers

Himalayan Rivers
Most of the Himalayan Rivers are perennial. It means water flows throughout the year.
Examples:
Indus, Jhelum,Chenab,Ravi,Beas,Satluj,,Ganga,Yamuna,Brahamputra

Peninsular Rivers
These rivers are broad, stable and flow through shallow valleys. Flow of water through these rivers depend upon rain, hence these rivers are seasonal.These rivers are further divided into two cetagories
West Flowing: Narmada, Tapti, Ghagghar, Luni, Sabarmati, Mahi.
East Flowing: Mahanadi, Godavari, Subarnarekha, Krishna, Kaveri, Pennar.

Some interesting Facts:
  • Indus river originates from Mansarovar in Tibet and called Sengge Khabab there.
  • Controversial Tulbul Project is located on Jhelum.
  • Longest irrigation canal i.e.Indira Gandhi Canal takes off from Harika barrage and runs up to Jaisalmer(Rajasthan).
  • Famous Bhakra Nangal Project also called as Govind Sagar Dam is located on Satluj river.
  • Ganga is the longest river of India with total length of 2510 km.
  • Famous Hirakund Project is located on Mahanadi.
  • Godavari is the longest Peninsular river of the India.

India-Physiography-Northern and Northeastern Mountains

Image
Northern and Northeastern Mountains    The Northern and the Northeastern Mountains consist of the Himalayas and the Northeastern hills.   The Himalayan Ranges  include  the  Greater Himalaya,  Lesser/Middle Himalaya, and the Siwalik Range.   Based on relief, alignment of ranges and other geomorphological features, the Himalayas can be divided into the following sub-divisions:   Kashmir or Northwestern Himalayas    Himachal and Uttaranchal Himalayas    Darjeeling and Sikkim Himalayas    Arunachal Himalayas    Eastern Hills and Mountains.  1) Kashmir or Northwestern Himalayas  Kashmir or Northwestern Himalayas consist of a series of ranges such as the Karakoram, Ladakh, Zanskar, and Pir Panjal. Important glaciers of South Asia, i.e., the Baltoro and Siachen are found in the Northwestern Himalayan region. The Kashmir Himalayas are also popular for the Karewa formations, whi...

PHYSIOGRAPHY OF NORTH EAST INDIA

Image
PHYSIOGRAPHY OF NORTH EAST INDIA The North East India region is physiographically not a homogenous unit and the present configuration of this region has taken shape during geologically recent time. But the ultimate result of various geological events took place through the geological past. North East India consists of very ancient Archaean and Shillong series rocks exposed in several parts of the Garo, Khasi, Jaintia and Karbi Hills. These rocks are similar to rocks exposed in the rest of the peninsular in Bengal and Bihar of which this was a part at one geological time. All these old rocks form the basement for very much younger Tertiary sediments in upper Assam.    A large part of this region was a landmass upto the formation of the Himalayas about 2,000 million years ago. Then the eastern part of the Khasi Hills, the Jaintia Hills and the Western pat of the Karbi Hills became a basin of sedimentation in which sandstone and shales of the Shillong series were deposi...

Climatic Regions of India (based on Koeppens Scheme)

Image
The classification of climate,is a complex exercise. There are different schemes of classification of climate. Major climatic types of India based on Koeppen’s scheme.Koeppen based his scheme of Climatic classification on monthly values of temperature and precipitation. He identified five major climatic types, namely: (i)Tropical climates, where mean monthly temperature throughout the year is over 18°C. (ii)Dry climates, where precipitation is very low in comparison to temperature, and hence, dry. If dryness is less, it is  semi- arid (S); if it is more, the climate is arid(W). (iii)Warm temperate climates, where mean temperature of the coldest month is between 18°C and minus 3°C. (iv) Cool temperate  climates, where mean temperature of  the warmest month is over 10°C, and mean temperature of the coldest month is under minus 3°C. (v)Ice climates, where mean temperature of the warmest month is under 10°C. Koeppen used letter symbols to denote climatic types as giv...
