Flood - Val d'Aosta (Valais, Swtizerland), October 2000
Valais, October 2000 - Heavy rains have caused problems in Switzerland and in northern Italy since Sunday 15 October. Sixty centimetres of water have fallen in two days over the Alps linking Italy, Switzerland and France. Rock slides and rushing water cut off many villages in Italy on Sunday, and high water shut down rail lines and roads, sometimes washing away bridges.
A series of ERS SAR satellite images were acquired during the flooding.
This night image covers the south-west part of Switzerland (cantons of Vaud and Valais). Some flooded areas are visible in the lower-right quarter of the image along the Rhone river before it arrives at the Leman lake.

This multitemporal image was created by merging the day-time acquisition of 16 October 2000 (orbit 28705, frame 2687) and 7 September 1998 (taken as reference orbit 17683) around the Aosta valley. The blue areas indicate floods.

The blue areas in the valley are the flooded areas. The blue on the mountains indicates fresh snow, or a change in the soil moisture.
