[5] 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.

[12] The Gulf of Khambhat was identified as a promising site for tidal power generation by UNDP Expert, Mr. Eric Wilson in the year 1975.

In the reservoir the runoff from Sabarmati, Mahi, Dhadar and Narmada will be stored, together with the waters from the Saurashtra rivers discharging into the Gulf of Khambhat.

[16] Kalpasar is considered the evident solution for solving on the short as well as on the long term the threatening drinking and irrigation water problems in Saurashtra.

In addition to fresh water storage and tidal power generation, Kalpasar also aims at land reclamation, transportation improvements and fisheries development.

This project, will resolve four vital problems of the State of Gujarat which are water, electrical power, road-rail transport and development of ports.

A state government release said the Rs 55,000 crore (US$11.7 billion) project, to be completed by 2020, will have a vast fresh water reservoir with gross storage of 16,791 million cubic metres of water, 64 km long dam across the Gulf of Khambhat connecting Ghogha in Bhavnagar with Hansot in Bharuch District, reducing the distance between the two by 225 km.

Another estimate was given by the Government in October 2010 which stated the proposed dam to be built just north of Bhavnagar in the west to Alandar in Dahej on the east.
