Floods and droughts are extreme events in the hydrological cycle, which describes how water moves throughout the earth in different ways and at different rates.

Floods
A flood is an overflow of water, an expanse of water submerging land, a deluge. Flooding and its impacts are often influenced by a combination of natural factors and human interference. Floods are the most common natural disasters in Europe and, in term economic damage, the most costly ones.

A river basin is the land area, from which rainfall drains into a certain river.\The Danube river basin covers ~8% of Europe.This term is also used in the EU Water Framework Directive, specifying that a river basinholds even an outlet to sea.The most vivid image of the water cycle is in the evaporation of water from the ocean, which forms clouds. These clouds drift over the land and produce rain. The rainwater flows into lakes, rivers, or aquifers. The water in lakes, rivers, and aquifers then either evaporates back to the atmosphere or eventually flows back to the ocean, completing a cycle.

Droughts
A drought is an extended period where water availability falls below the statistical requirements for a region. Also drought is not a purely physical phenomenon, but an interplay between natural water availability and human demands for water supply. Since the demand for European water resources is increasing, also the pressure on water continues to grow and Europe is becoming increasingly vulnerable to the effects of periods without rainfall.
