Flood Early Warning System

The occurrence of floods are increasing every year due to climate change. Communities need to invest on early warning systems to make communities more resilient. 

1st Method: Data Moves Faster than Flood

Here an automatic river gauging station is installed on the upstream

An alerting mechanism is placed on the downstream

Lead time proportional to the distance



2nd Method: Probabilistic Forecasting

  • Automatic Rain Gauges in the basin
    • Representing sub basins
  • Automatic River Gauging 
    • Measuring river stages
  • Numerical Probabilistic models forecasting river stages.
  • Adds 2 to 7 hours lead time


3rd Method: Hydrological Models

  • Hydrologic Modelling System is designed to simulate the complete hydrological processes of dendritic watershed systems. 
    • HEC-HMS
    • MIKE II
  • Meteorological forecast can be used for forecasting floods many days ahead
