It irrigates northern part of Firozpur district in Punjab. It is this efficient canal system which has enabled this area to be called as the granary of the country and nucleus of the Green Revolution. This is followed by seed spices — jeera cumin , variyali fennel and dhaniya coriander — in the rabi winter season. The western canal is known as Saran Canal and irrigates 7-6 hectares of Saran district of Bihar and Deoria and Gorakhpur districts of Uttar Pradesh. It is remarkable that the protection objective has remained a central element of Indian irrigation policy, also after independence, despite the recognised practice of unequal water distribution.
To replace these, new rules have been adopted that on the one hand consolidate inequality, but on the other hand provide a more realistic basis for negotiating water supply to the downstream part of the canal. This canal and its branches irrigates the vast expense of Punjab and Haryana namely cities like Ambala, Karnal, Rohtak, Jind, Hissar etc. Two canals taken out of the Godavari a Darana dam irrigate about 27 thousand hectares in Nashik and Ahmednagar districts Canals taken out from Gangapur dam at Godavari irrigate 33 thousand hectares in Nashik district. Construction of this canal was completed in year 1882. Its main branches are Etawah, Kanpur and Fatehpur. The distributary Canals — Champakara and Udyogmandal canals also connects the industrial parts of Kochi to Kochi port.
The migrants bought land from local farmers. The construction work on this canal was completed in 1928. The system is located in interior South India, where rainfall is limited approximately 600 mm annually and extremely variable. The total length of Rajasthan Feeder is 204 km. Further beyond, these two canals flow separately. Things are somewhat different in Mansar, a village in Halvad taluka of Morbi district.
Many types of social evils are generated in canal areas. The main canal has two kinds of branches and distributaries. Indian governments has launched many projects for rivers Inter link and National Waterways. It again joins the Yamuna River at Delhi and irrigates a part of the union territory also. This is the second highest percentage for any state after Chhattisgarh. The cities like Bikaner, Barmer, Jaisalmer of Rajasthan are the most gaining cities from this canal.
Other major states where irrigation is done by canals are Madhya Pradesh, Andhra Pradesh, Haryana, Punjab and Bihar. With increased requirements, the total length of main, feeder and distribution canals was about 9,245 km 5,745 mi. It has a total length of 3229 km with distributaries and provides irrigation to about 4. These are the design process of canal irrigation technology, the political dimension of irrigation, and the issue of use r rights. This canal originates from Harike Barrage at Firozpur. Sometimes water scarcity developed in areas where sufficient water was available earlier. Uttar Pradesh: Canals constitute an important source of irrigation in Uttar Pradesh.
The length of main canal is 342 Km but with distributaries included the total length becomes about 6000 Km. Sirsa branch is one of the largest branch of this canal which was built in 1895. The total arable land in India is 160 million hectares 395 million acres. Upper Bari Doab Canal: This canal is taken from the Ravi River at Madhopur near Pathankot. The characteristics and the state of the outlet structures are an expression of the relationships between different groups of farmers along the canal and between farmers and the Irrigation Department. The eastern canal is called Tirhut.
Upper Ganges Canal The Upper Ganges Canal is the main canal of Ganges canal system projects, which starts Haridwar to Aligarh district via Meerut and Bulandshahr. In 1945 construction of the project started. But the amount of rainfall, especially in western parts of the state, is not sufficient for sustained agricultural growth. Canals are fed by rain water received by rivers, and the water is used for irrigation. Such canals provide irrigation mainly in the rainy season when the river is in flood and there is excess water.
Major States under Tank irrigation The Tank irrigation is more in the rocky plateau area of the county, where the rainfall is uneven and highly seasonal. Indira Gandhi Canal: This canal originates from Harike Barrage near the confluence of Satluj and Beas rivers in Ferozepur district of Punjab. Pumea, Muzaffarpur, Darbhanga, Champaran and Saran districts are benefited by this project. Dams used for irrigation projects help produce electricity and transport facilities, as well as provide drinking water supplies to a , and prevent droughts. Gurgaon Canal-it takes off from the Yamuna River at Okhla near Delhi. It joins with the Lower Ganga Canal at Mainpuri and the water in this canal is considerably increased.
