  • The significance of extreme events in landform change is discussed in the context of the late Quaternary. Millennia-scale cycles of climate change are less than the relaxation times of most landform systems and have led to widespread disequilibrium
  • time and research needs to establish the role of individual events within this timescale of enquiry.

  • High-magnitude landslide events on a limestone-scarp in central Germany : morphometric characteristics and climatic controls
  • This paper explores which external climatic variables of difference temporal scales influence the occurrence of high-magnitude landslide events. The investigations were focused on the Wellenkalk-cuesta scarp in the Thuringia Basin. Rainfall
  • parameters of different temporal scales (annual rainfall to extreme short-time rainfall events) are analyzed in the context of the given morphostructural, morphometric and geological setting.

  • Postglacial extreme events and human action in the transformation of Estonian topography and landscapes
  • Extreme events and the transformation of landscape
  • In Estonia, extreme events have been caused by meteorite explosions, earthquakes, and neotectonic processes, heavy storms, karst phenomena and human impact. Investigation of past processes provides a major key in predicting the changes that could

  • -September, the rainy season. Heavy rain evenys show no significant show no significant secular trend. There is a weak and non-significant upward trend in frequency of extremely high temperatures from the 1950s to the mid-1990s. But the number of hot events
  • increases as much as twice since 1997. The frequency of low temperature events have been decreasing steadily since the 1950s.

  • The disasters associated with hazards, of exogenous and endogenous origin, are particularly severe in densely populated regions and in areas more vulnerable to extreme events because of environmental and/or economic marginality. Extreme events

  • deforestation began, sediment production has largely been determined by landslide events. On unstable slopes, thousands of landslides were triggered by high-magnitude/low-frequency climatic events during storms with estimated return periods in excess of 50 years
  • . In contrast, low-magnitude/high-frequency rainfall events have caused gully and channel erosion.

  • The relationship of extreme precipitation events to weather conditions in Nordland, Norway
  • The AA. examined the distribution of extreme daily precipitations events in relation to weather conditions, in the county of Nordland. Precipitation data included 88 weather stations and cover the period January 1964 - March 2002. Over this period

  • On September 19, 2000, Marseille (South of France) have been flooded by a very strong rainfall event. Rainfall measurements from two sensors with different spatiotemporal characteristics rain gauge and radar have been used in order to compare
