Pls read the above paper. I am open for collaboration.

It is important to collect stream and water level information as suggested to make informed decisions. But efforts to redesign a network of rivers and perhaps management of storage dams appears excessive at the country scale. Many historic efforts to hydrologically modify rivers have lead to a variety of benefits and costs, and occasionally failures through time that were never anticipated. It seems appropriate to work on a case by case, or perhaps watershed or basin basis, have ample planning and Involvement of communities, landowners, resource experts, and any water, wildlife or other regulatory agencies. Redistribution of water has potential for gains or losses in wealth, habitat, land values, etc., so some degree of mitigation or resolution of claims might be appropriate for those with valuable land or resources with significant loss. Altering stream networks can also influence sediment mobility, channels affected by aggradation from sediment loading, encroachment by vegetation, and changes in flooding potential. A variety of methods such as small dams or reservoirs, drip irrigation and rainwater storage have been used to help adjust activity in conjunction with or anticipation of limited water supply.
William F. Hansen I agree that you have a valid point, and in a country like India with 1.3 billion population, and a huge number of rivers separated geographically.
Butt my idea is for a social cause, because my country has 2 extremes, regions of extreme flooding and regions of scarcity creating drought. But tax money collected is very much enough to create a network.
Thank you for replying and showing interest to my research proposal.
Hi Siddesh, on a theoretical level, networking rivers sounds like a workable solution to carry water from water-surplus regions to arid areas. However, there are very significant social and ecological costs, apart from hydrological issues. Diverting water from say the Ganga basin to the deccan or south will lead to reduced flows with lower annual floodplain sedimentation (farming depends on that), in the estuaries of the sunderbans, with sea water intrusion into coastal village wells n farms, that also affect growth and development of marine fish that come to the estuaries to breed. Decreased nutrient inflows can stress seagrass beds and the ecosystem that depends on them - a stressor to marine fisheries. It is necessary to remember that ecosystems have evolved with the prevailing flows in rivers, and a drastic change to that upsets the biogeochemical and ecological systems. Then, much of the water being transported more than a 1000 km south can evaporate, leading to higher salt concentrations in the river. Furthermore, invasive species can get introduced, leading to other problems - such as happened with snails, fish, algae and even waterborne parasites ( The Careless Technology has a collection of such failed development schemes worldwide, from neglecting to consider the ecosystem and possible ecological impacts. These are just a few of the irreversible impacts. Good question.
I agree with all the above researchers, this river interlinking is nothing new and comes with few benefits and more losses. It's better to do it at a small scale if at all, after carrying out rigorous investigations on ecological, social and hydrological aspects.
