Answer : (a)
Related facts
- The Energy and Resources Institute (TERI) and National Disaster Management Authority (NDMA) have launched a Flood Early Warning System (FEWS) for Guwahati to alert local authorities about flash floods and/or heavy rainfall.
- Developed under TERI’s project supported by the NDMA in collaboration with the India Meteorological Department (IMD) and the Assam State Disaster Management Authority (ASDMA), the tool can be replicated to predict urban floods in any part of the country.
- The FEWS pilot project was undertaken on an experimental basis, to enhance resilience for urban floods, in assistance with the Guwahati Municipal Corporation, North Eastern Space Applications Centre (NESAC) and TERI School of Advanced Studies (TERI SAS).
- This is in line with Prime Minister Narendra Modi’s recent statement during a meeting with the Chief Ministers of six states—Assam, Bihar, Uttar Pradesh, Maharashtra, Karnataka and Kerala—wherein he highlighted the need for development of local-level flood warning system.
- FEWS uses IMD’s weather research forecast (WRF) model results of precipitation at 3 Km spatial resolution having hourly data set to simulate the hydrodynamic model for flood prediction and sends out early warning.
