GFMS

Overview

The GFMS is a NASA-funded experimental system using real-time TRMM Multi-satellite Precipitation Analysis (TMPA) precipitation information as input to a quasi-global (50°N - 50°S) hydrological runoff and routing model running on a 1/8th degree latitude/longitude grid. 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 (95th percentile plus parameters related to basin hydrologic characteristics). Streamflow,surface water storage,inundation variables are also calculated at 1km resolution.In addition, the latest maps of instantaneous precipitation and totals from the last day, three days and seven days are displayed.

Flood forecast map for Hurricane Irma
Some heavy rainfall in Haiti and Domincan Republic produced river flooding as Irma skirted to north of island. The above image shows the NASA GEOS-5 rainfall forecast over next three days with Irma tracking up center of Florida peninsula with maximum rainfall from southern tip and along east coast with amounts over 300 mm (12”).  Also seen are rainfall tracks of Katia...

Flood estimates from GFMS using IMERG input show evolution of flooding over 8/26-8/29, with expansion from Houston area to southeastern Texas and Louisiana.
Flood estimates from GFMS using IMERG input show evolution of flooding over the last few days, with expansion from Houston area to southeastern Texas and Louisiana.    Satellite-based rainfall (GPM IMERG) from now Tropical Storm Harvey over the last three days compares fairly well with raingauges, except for peak values.  IMERG has peaks of about...

GFMS flood detection map from January 8th 2017
Northern and Central California are under flood threat from an "atmospheric river" in the Pacific.  Some flooding has already occurred.  Rainfall forecasts below show a pattern extending from ocean and the effect of orography.  A forecasted flood pattern from GFMS for Sat., Sun. and Monday is shown in next three figures. The last chart shows forecasted streamflow on American River upstream from Sacramento (near Fair Oaks streamgauge, 38.57N, 121.36W) showing very high values peaking on Monday, but with continuing high values after that (75 cu. m/s is flood...

GFMS Inundation Estimates
Routing and inundation calculations at 1 km resolution give a more detailed estimate for flooding location and depth.  Results for today show flooding along Mississippi (although protected by levees, etc.) and areas of flooding in southwest LA and into Texas. GFMS Inundation Estimates Streamflow and Inundation at 1 km Resolution Maps of streamflow and inundation allow finer diagnosis of locations of high streamflow and flooding.  In this expansion of map from previous slide...

GFMS flood detection / intensity
Heavy rain  from a tropical system—over 300mm in the last week, with most of that coming in the last three days has caused heavy flooding in Louisiana.  The Global Flood Monitoring System (GFMS) has been used to analyze the event in real-time.  These slides summarize the results.  The images in this slide show the rainfall amounts as of Sunday (14 August) and the pattern of floods at the 12 km resolution.  The following images show the pattern of evolution during the last few days and the forecast for the next few days. ...
