Impact Based Forecasting Approach: IMD develops technology to assess rise of water level in rivers

India Meteorological Department (IMD) has developed new technology called ‘Impact Based Forecasting Approach’ to assess rise of water level in rivers and reservoirs by rain.  It shows pre-event scenario will help state governments authorities to minutely monitor impact of rainfall and take real-time decisions. It will help to avoid disastrous situation similar to Kerala floods. It can generate scenario to help take decisions to release water or not from reservoirs after heavy downpour. It will be helpful for every state authority to take decision. This system can be run in pre-event scenario.

Background

The heavy downpour which had ravaged Kerala in August 2018 had caused death of around 500 people and economic damages worth over Rs 40,000 crore. Excessive rainfall had led to floods in Kerala and was result of climate change. State Government had blamed IMD for lapses in its part for wrong rain forecast. IMD had forecasted estimated 98.5 mm rain in the state between 9 and 15 August, 2018 but Kerala received was 352.2 mm of rainfall resulting in severe flooding.

India Meteorological Department (IMD)

It is national meteorological service of the country and chief government agency dealing in everything related to meteorology, seismology and associated subjects. It was formed in 1875. It functions under Ministry of Earth Sciences. It is headquartered in New Delhi.

Mandate

  • Undertake meteorological observations and provide current information and forecasting information for most favorable operation of weather-dependent activities such as irrigation, agriculture, aviation, shipping etc.
  • Offer warning against severe weather phenomenon such as tropical cyclones, norwesters, dust storms, heat waves, cold waves, heavy rains, heavy snow, etc.
  • Provide met-related statistics needed for agriculture, industries, water resources management, oil exploration, and any other strategically important activities for the country.
  • Engage in research in meteorology and allied subjects.
  • Detect and locate earthquakes and evaluate of seismicity in various parts of the country for developmental projects.
