CRZ Management Studies

The Coastal Regulation Zone (CRZ) Rules govern human and industrial activity close to the coastline, in order to protect the fragile ecosystems near the sea. The coastal regulation zones have been declared by the Ministry of Environment, Forest and Climate change under the Environment Protection Act 1986. The structured programme, undertakes the formation of trained manpower capable of redressing identified problems and helping to build capable institutions.

Marine Impact Assessment

Our multidisciplinary marine consultants and environmental specialists provide consultancy on a wide range of topics including:

  • Marine consenting
  • Environmental impact assessments (EIA) and appraisals
  • Zonal and regional assessments
  • Habitat regulations appraisal (HRA) and appropriate assessments
  • Environmental policy and legislation
  • Characterisation and feasibility studies, desktop studies, site selection and appraisal
  • Management plans (construction, environmental, spill mitigation)
  • Licensing
  • Marine ecology
  • Marine geology
  • Physical processes
  • Water quality
  • Fisheries
  • Environmental management
  • Geographical information systems
  • Marine Ecological Studies

Marine Ecology is the scientific study of marine-life habitats, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment). Marine ecology is a subset of the study of marine biology and includes observations at the biochemical, cellular, individual, and community levels as well as the study of marine ecosystems and the biosphere.

The study of marine ecology also includes the influence of geology, geography, meteorology, pedology, chemistry, and physics on marine environments. The impact of human activity such as medical research, development, agriculture, fisheries, and forestry is also studied under marine ecology.

  • Post-drill and decommissioning surveys
  • Marine mammal and seabirds
  • Desk-studies to characterise development area and inform survey design
  • Data acquisition and monitoring to generate pre-, during and post-construction data
  • Ornithological survey
  • Visual marine mammal survey
  • Passive acoustic marine mammal survey
  • Marine mammal protection plans
  • Data storage and management, data analysis and interpretation, environmental statements (ES) and environmental impact assessment (EIA)

Brine Discharge Dispersion

Brine discharged directly into the sea from desalination processes, forms a very dense plume that spreads out over the sea floor following the steepest slope due to its greater density than ambient sea water. The behaviour of this brine discharge was characterized under various hydrodynamic conditions. Brine is a water solution that contains high concentrations of one or many kind of salts. It may occur naturally (e.g. salt lakes, underground, seawater, etc.) or from industrial processes. Modelling Studies on the effect of coastal water depth variations upon mixing and spreading of brine waste continuously being discharged are presented.

Shore Morphology Studies

Shoreline changes on account of global climate change and sea level rise is one of the major problems along the coastlines in different continents of the world. Long-term coastal erosion and accretion rate over a period of 42 years has calculated using Digital Shoreline Analysis System and prepared shoreline maps by using GIS-Software. End point rate (EPR) statistical method is applied to estimate the shoreline change rate. Various coastal parameters like sea level rise, geomorphology, elevation and coastal slope were used to find out the interactive relationship between the physical parameters and shoreline changes in the area.
