Vasna Barrage is a barrage on the Sabarmati river in Ahmedabad, Gujarat, India. Constructed in 1976, the barrage is meant for strengthening the existing irrigation system. [1] [2] [3]
The barrage holds the water in the part of river in Ahmedabad throughout the year and supplies drinking water to the city. It also feeds underground water aquifers in the region. [4] [5] The bedrock is of river deposits. Total 87 villages of Ahmedabad district fall under its command area. The right bank irrigation canal called Fatehwadi canal is 6.9 km long and was completed in 1978. It has discharge capacity of 45.35 cubic metre per second. [2] [6] The canal supplies water only when the river overflows. [7]

The Sun Koshi's tributaries from east to west are Dudh Koshi, Likhu Khola, Tamakoshi River, Bhote Koshi, and Indravati. The Saptakoshi crosses into northern Bihar, India where it branches into distributaries before joining the Ganges near Kursela in Katihar district. Kosi is the 3rd largest tributary of the Ganges by water discharge after Ghaghra and Yamuna.
The Indus Water Treaty (IWT) is a water-distribution treaty between India and Pakistan, arranged and negotiated by the World Bank, to use the water available in the Indus River and its tributaries. It was signed in Karachi on 19 September 1960 by then Indian Prime Minister Jawaharlal Nehru and then Pakistani president Ayub Khan.
The Indian Rivers Inter-link is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking Indian rivers by a network of reservoirs and canals to enhance irrigation and groundwater recharge, reduce persistent floods in some parts and water shortages in other parts of India. India accounts for 18% of the world population and about 4% of the world’s water resources. One of the solutions to solve the country’s water woes is to link rivers and lakes.
Sabarmati Riverfront is a waterfront being developed along the banks of Sabarmati river in Ahmedabad, India. Proposed in the 1960s, the construction began in 2005.

The Kalpasar Project or the Gulf of Khambhat Development Project envisages building a 30 km dam across the Gulf of Khambat in India for establishing a huge fresh water coastal reservoir for irrigation, drinking and industrial purposes. The project with 30 km sea dam will have the capacity to store 10 billion cubic meters fresh water, equating to 25% of Gujarat’s average annual rainwater flow, from the rivers like Narmada, Mahi, Dhadhar, Sabarmati, Limbdi-Bhagovo, and two other minor rivers. A 10 lane road link will also be set up over the dam, greatly reducing the distance between Saurashtra and South Gujarat. The project, which will create world's largest freshwater lake in marine environment, will cost INR90,000 crore or US$12.75 billion excluding the cost of tidal power plant. Project entails construction of the main "Kalpasar dam" across Gulf of Khambat and another Bhadbhut barrage on Narmada river, as well as a canal connecting the two.

It was commissioned by Prime Minister Morarji Desai in 1979. It mainly functions as an irrigation dam, serving a command area of 11,525 hectares in Iritty taluk of the Kannur District. The water from this dam also meets the drinking water requirement of Kannur district. The dam site and the reservoir are known for their scenery.
Irrigation in India includes a network of major and minor canals from Indian rivers, groundwater well based systems, tanks, and other rainwater harvesting projects for agricultural activities. Of these groundwater system is the largest. In 2013–14, only about 36.7% of total agricultural land in India was reliably irrigated, and remaining 2/3 cultivated land in India is dependent on monsoons. 65% of the irrigation in India is from groundwater. Currently about 51% of the agricultural area cultivating food grains is covered by irrigation. The rest of the area is dependent on rainfall which is most of the times unreliable and unpredictable.
