Die Kosten f\u00fcr die weltweiten Hochwassersch\u00e4den belaufen sich auf Hunderte von Milliarden Euro. Allein die \u00dcberschwemmungen in Pakistan im Juli 2010 verursachten Sch\u00e4den in H\u00f6he von mehr als 7 Milliarden Euro.<\/p>\n<\/div>\n<p>\u00dcberschwemmungen k\u00f6nnen in K\u00fcstengebieten oder in der N\u00e4he von Fl\u00fcssen auftreten. Wenn riesige Wassermassen tief liegende Gebiete \u00fcberfluten, k\u00f6nnen sie enorme Sachsch\u00e4den verursachen und Menschenleben gef\u00e4hrden.<\/p>\n<p>Die europ\u00e4ische Raumfahrttechnik ist eine der Hauptwaffen im Kampf gegen \u00dcberschwemmungen. Die erste Verteidigungslinie stellen dabei die Meteosat- und MetOp-Wettersatelliten dar. Sie zeigen sich entwickelnde Sturmsysteme auf und erlauben es, genaue Vorhersagen \u00fcber Wind und Regen zu machen.<\/p>\n<p>Gew\u00f6hnliche Kameras k\u00f6nnen \u00dcberschwemmungen bei Tageslicht und klarem Himmel aufzeigen.
