GFMS Flood Forecasts of 2017 New Zealand Floods

The GFMS uses real-time TRMM Multi-satellite Precipitation Analysis (TMPA) precipitation information as input to a quasi-global hydrological runoff and routing model. 

  • In addition, the latest maps of instantaneous precipitation and totals from the last day, three days and seven days are displayed.
  • Flood detection/intensity estimates are based on 13 years of retrospective model runs with TMPA input, with flood thresholds derived for each grid location using surface water storage statistics. 
  • Streamflow, surface water storage, and inundation variables are also calculated at 1km resolution.
