Interlinking of Rivers (Godavari–Krishna–Pennar–Cauvery)

The present study examines the purpose of interlinking of rivers, which benefits mankind. It primarily focuses on interlinking the rivers by creating a system of manually developed canals where the river water is not attainable. The proposal is based on diverting the surplus water from the rivers receiving the high floods to the deficit rivers by connecting the manually developed canals. So, it will assist in diverting surplus water to the deficit rivers in case of necessity. The idea is to design canals that connect the rivers Godavari, Krishna, Pennar, and Cauvery to control floods and use surplus water for irrigation and other purposes. Manning’s method is used for the design of canals. Flood frequency analysis has been shown for these four rivers. This analysis played a major role in executing the plan. According to the flood data, the rivers Pennar and Cauvery have had very low floods over the years, whereas the rivers Godavari and Krishna experience the high number of floods. So, the flood water is set to be diverted to the rivers Pennar and Cauvery. These auspicious results have enlarged the potential of success in planning. The main objectives are to draw water from the Godavari River to the Krishna River (Detailed notes on “Krishna River” by Wikipedia), from the Krishna River to the Pennar River, and from Pennar River to the Cauvery River. This can be ended by linking the reservoirs situated across these rivers by the link canals.
