What is common to the places known as Aliyar, Isapur and Kangsabati?

Let's identify the nature of each place: Aliyar: Refers to the Aliyar Dam and Reservoir located in Pollachi taluk, Coimbatore district, Tamil Nadu. It is a significant multi-purpose project primarily for irrigation and power generation. Isapur: Refers to the Isapur Dam, also known as Vishnupuri Prakalp, located on the Godavari River in Nanded district, Maharashtra. It's a large irrigation project serving agricultural needs in the region. Kangsabati: Refers to the Kangsabati Dam and Reservoir, located in Bankura district, West Bengal, on the Kangsabati River. It is a major irrigation project providing water to vast agricultural lands. The commonality among Aliyar, Isapur, and Kangsabati is that all three are locations of significant water reservoirs or dam projects, primarily constructed for irrigation and water supply purposes.
