Research Project: A New-Generation Flood Forecasting System Using Observations from Space

Location: Hydrology and Remote Sensing Laboratory

2013 Annual Report

1a.Objectives (from AD-416):
To apply a novel hydrologic data assimilation scheme to improve the Australian Bureau of Meteorology’s operational flood forecasting system through the assimilation of remotely-sensed soil moisture into a hydrologic forecasting model.

1b.Approach (from AD-416):
The approach will be based on a recently developed data assimilation system that allows for the simultaneous correction of both antecedent soil moisture (in a hydrologic model) and incident rainfall feed into a hydrologic model. The approach will be applied and tested over several Australian river basins.

3.Progress Report:

This project seeks to integrate USDA ARS remote sensing and data assimilation tools into the operational hydrologic forecasts made by the Australian Bureau of Meteorology. Year 2 project objectives focused on the successful assimilation of remotely-sensed surface soil moisture products into a hydrological model for 10 test catchment within the United States. This objective has been met and follow-on work will focus on a parallel implementation within a comparable set of catchments in Australia.
