The main objectives of the project were:

  • Monitoring & studying the impact on ecology due to sewage plumes of marine outfalls off Mumbai coast in the post-installation scenario.
  • Studying the plume propagation pattern and the factors influencing the pollutant flow.
  • Futuristic modelling of the impact on coastal and marine eco-system.

The project intended to use remote sensing techniques to develop a monitoring model to monitor the pollution in the sea due to sewage outfalls and further aimed at simulation of future plume propagation towards prediction of impacts. The research involved a comparative study of pre-and post-Marine outfall installation scenario of marine pollutant plume. The project comprised of methodology development for pollution mapping and modelling of the flow dynamics of effluent. The final output was useful for mapping the ecological impact and the probable zones of plume propagation which may help in decision making and further implementation of similar outfalls.

The scope of work included:

  • Compilation of various baseline data, a pre-processing of satellite image and mapping of ambient waters in the vicinity of the outfalls prior to the installation at Bandra & Worli regions.
  • Plume mapping, simulation of ambient pollution and mapping of impact on ecosystem
  • Analysis of plume propagation estimation of future propagation trends of plume and prediction of impact of pollution on ecosystem.
