Coastal Hazards

Coastal Hazards

Development of Coastal Flood Warning System  

Floods have been a recurrent phenomenon in India from time immemorial and are almost becoming an annual phenomenon now as floods of varying magnitude affect different parts of the country. In the past decades extreme rainfall events have increased resulting in floods of unprecedented nature with large scale damage to lives, livelihood, infrastructure and property. These include the 2018 - Kerala Floods, 2017 - Mumbai Flood and West Bengal Floods. 2016 - Brahmaputra Floods, 2015 - Chennai Floods, 2014 - Kashmir Floods and 2013 - North India Floods and the 2005 flood in Mumbai which brought the financial capital of India to a standstill. India is a signatory to the Sendai Framework for Disaster Risk Reduction (2015-2030) which stress on the need to identify, assess, and monitor disaster risks and enhance early warning systems to mitigate and manage the impacts due to hazards. NCCR has worked in developing operational state-of-art early flood warning system for two metropolitan cities namely Chennai and Mumbai.

  • NCCR supports Indian Metrological Department (IMD) in the development of an  operational Multi hazard Early Warning System (MHEWS) and  Impact based forecasting for tropical cyclones is being attempted as part of this work.
  • Indo-UK  Collaboration under the Newton-Bhabha fund Weather and Climate Science for Service partnership Programme, NCCR is involved in studies related to  Risk based forecasting and high impact weather/seasonal events.

Decision support system for climate change impact assessment and management in coastal areas

The work integrates the output of downscaled climate, circulation, morphodynamic models to represent the exposure to climate change hazards (e.g., Sea level rise, flooding, erosion) and includes the analysis of site-specific environmental and socio-economic vulnerability of coastal systems to the impact of hazards (e.g., land use, geomorphology, vegetation cover, population density). A GIS-based Decision support system for Coastal climate change impact assessment will be developed that will provide information on regional/local vulnerabilities and risks to guide decision-makers in planning appropriate adaptation strategies.

Dissemination of Scientific tools and technology to the State Government to aid in their Disaster Risk  Reduction (DRR) activities

  • NCCR and Dept of Fisheries, Govt. of Tamil Nadu have developed  a WebGIS based decision support system and mobile based app (Thoondil) with data from IMD, INCOIS  as a reach and rescue tool for the fishermen specially during hazard times.
  • NCCR and Kozhikode administration, Government with Kerala have initiated work on developing  geospatial expert systems  for management of coastal resources and disasters in the district.
