For river rejuvenation, some works are done with immediate impact and some with long-term impact. Raman is doing three types of work in the field of river rejuvenation - groundwork, research work, and policy work.
Raman started his efforts to change the feeling of despair towards small rivers in the country into hope in the year 2006 by doing a technical study of the Hindon River and doing a trek on it. Based on ground experiences of river trekking and technical study, a map of Hindon and its tributaries was prepared, which is used today at all government and non-government levels. During this period, the origins and flow paths of the Hindon and all its tributaries Kali West, Krishna, Nagdeh, Pavdhoi, Chhajjewali, Peerwali, Barsani, Sapolia, Peerwali and Andhakundi were discovered.
In the year 2012, Raman completed the technical study of the East Kali River, the main tributary of Ganga, in collaboration with WWF. In the year 2016, the origin of East Kali River was identified in Antwada village of Muzaffarnagar district. With the cooperation of society and administration, 15 hectares of land at the river source was freed from encroachment and the river source was revived by constructing a lake here. At present, there are 15 feet of water here. Due to these efforts, the East Kali and Hindon rivers were included in the Namami Gange scheme. Due to the efforts made for the East Kali River, Raman was given the National Water Award in the year 2020 by the Ministry of Jal Shakti, Government of India.
