Æ Climate Changes Risk Information System (CRIS): CRIS is deployed to study the vulnerability of the coastal areas to various coastal hazards such as tsunamis, Storm surges, sea level rise etc. Several large- and small-scale maps can be prepared to indicate areas vulnerable to these hazards. Web-GISbased decision support systems have been developed to calculate the physical, ecological, social, and economic vulnerability of the coastal areas to these hazards. Æ Coastal Pollution Dashboard: This tool is used to study coastal water pollution and predict coastal water quality across the Indian coast. Programmes related to marine litter and marine plastics have also been initiated in connection with tackling coastal pollution. All these datasets are stored in a

Geo-database, are analysed and the results are displayed using spatial dashboards.

Use of Geospatial Technologies

Geospatial technology coupled with numerical modelling and field investigations forms the backbone of most of the research activities carried out by NCCR. Thematic spatial data pertaining to the coast and nearshore are collected from the field using various instruments such as RTK-GPS, echo sounder, data buoys, ADCP, AWS etc. Optical and microwave remote sensing datasets are used to generate temporal data to assess the changes over time. The data is analysed in a GIS platform and the end products are developed as Web GISbased applications for easy dissemination and usage. Geospatial technology coupled with numerical modelling is used extensively in multiple projects related to Coastal Hazards and Processes. Key Outputs

y Sea water quality index generated for Indian coastal waters based on the past 25 years of water quality data collected through the Seawater Quality Monitoring program (SWQM). y Water quality prediction with 5 days of forecast indicating water quality parameters developed for major beaches at Chennai, Puducherry, and Puri coast. y Automated water quality buoy deployed off Chennai for the collection of real-time water quality data at every 20 minutes interval. y Forecast for coastal water quality parameters for Marina, Elliot and Thiruvanmiyur beaches being made 5 days in advance. y Information on the health of coastal waters is disseminated through a web-based forecasting system and a mobile app called "Clean Coast". y Android app and dashboard SS Sagar specially developed to collect marine litter-related data during beach cleaning and analysis operations.
