WHAT ARE THE KEY POINTS OF WAMM ?

• “cloud piercing capability”

SAR DETECTS THE EXTENT OF FLOODED AREAS DURING NIGHT AND CLOUDY CONDITIONS

• Soil Moisture Information

BASED ON SAR IMAGERY (Synthetic Aperture Radar)

h1 h2 h3 h4

IS TO ENHANCE FLOOD FORECASTING:

• Innovative monitors

SMALL PORTABLE SENSORS FOR FAST INSTALLATION OF FLOOD EXTENTS

AIMS OF THE WAMM PROJECT

Provide river authorities, civil protection

bodies, etc with a DSS allowing for:

1. Facilitate flood warning alarms

2. Improve management of floods

3. Provide reliable flood defence programs

4. Plan remediation measures to account

for climatic change
