AbstractSouth Asia is more vulnerable to water disasters due to impacts of climate changes in recent years. In an extreme climate change phenomenon during last week of July 2005 , causing heavy rains and flooding situation in the river basins of state of Maharashtra .More than 20 million population along coastal region and 50 million all over the state are witnessing the social- economical and ecological risks and impacts due to climate changes in river catchments .The economic losses to social and economical infrastructure are very high due to extreme water -disasters such as floods, cyclones, Tsunami etc. that are linked with environmental and climate changes . Mitigating the river-disasters, Estuarine and marine hazards and rehabilitation during post tsunami period , scientific knowledge is needed, requiring experienced research communities who can train the local population during tsunami rehabilitation.Institute for sustainable development and research ;AVC College of engineering , India and Commission on Groundwater -Seawater Interactions, Switzerland jointly started the initiatives on the problem identifications in management of risks in flood-disasters, tsunami rehabilitation etc., to investigate problems related to social-economic and ecological risks and management issues to aid mitigation planning in affected areas and to educate scientists and local populations to form a basis for sustainable solutions. This presentation reviews the status of river linking and issues of Geo-risks, Estuarine and marine risks along Indian river basins focusing on technical issues, problems and damage arising from the extreme river floods, tsunami in agriculture, aquaculture, irrigation, drinking water, coastal infrastructure, coastal ecosystems and coastal economic systems. This study signifies that climate changes and risk management river linking is needed for mitigating potential river flood risks , Geo-marine risks in this region for capacity building for climate changes and rehabilitation issues based on local resources. The paper will also explore the issues concerned with achieving environmental, social and economic sustainability through corporate strategies and innovative geosciences information delivery for river linking for the water disaster affected communities. The paper also discusses role of information technology and its application for flood hazards, Estuarine and marine hazards; risk management and sustainability aspects that deal with river linking and natural resources development along coastal zones, management and flood disaster management planning. The paper will also explore the issues of new water sources in river catchment through rainwater harvesting through river linking with achieving environmental, social and economic sustainability in river catchments region through corporate strategies and innovative geosciences information delivery and Tsunami education for the affected communities.
