This book provides a detailed overview on methods used for the dating of past torrential activity on fans and cones and fosters the discussion on the impact of past and potential future climate change on torrential processes. The book has a clear focus on the practical applications of these methods, complemented by case studies. The limits of each dating method in case of excessive natural and human interventions on fans and cones are shown.

Alluvial fans and debris cones are fan- or cone-shaped sedimentary structures that are formed where a stream or torrent flattens, slows, and spreads. Moreover cones are also formed by scree deposits, rock avalanches, slope-type debris flows, mudflows, lahars, landslides, sheet floods and other forms of rapid mass movements.

Alluvial fans and debris cones are typically located in mountain fronts and develop at the base of headwater basins. The apex of the depositional environment is usually located within a canyon or ravine mouth that serves as the outlet for a mountain drainage system or at the juncture of steeper hillslope tributaries with the main stream in a flatter plain e. Inherited and present-day processes in the watershed actively influence water and sediment regimes and can thus lead to significant changes in the timing, frequency, and magnitude of hydrogeomorphic events.

The scarcity of event occurrence and the widespread absence of hydrogeomorphic disasters over several decades in the twentieth century represent a major handicap for an appropriate assessment of the frequency and magnitude of past and potential future events. Records of past hydrogeomorphic activity are stored in many different types of archives. Besides the classical anthropogenic archives, nature provides many sources of information that can be extracted using the appropriate methods.

A broad spectrum of methods allowing the improvement of data series on past hydrogeomorphic events on fans and cones are introduced in this chapter and further described in this book.

The event will instead provide four official 10k courses around the region for registered participants to complete a 10k on their own from Friday, September Sunday, September 27, and a virtual option remains in place for participants to take part on a route of their choosing as well. The course locations and maps can be found online at www. Each course will have a start and finish line, mile markers, and directional signage, and can be accessed from dawn to dusk September September

Water-related processes such as floods, debris floods, flash floods, and debris flows represent major geomorphic hazards in mountain areas of the world. Recent decades have seen human pressures on these regions increase, aggravating conflicts between natural hazards and infrastructure. Detailed knowledge on frequency and magnitude of past flood or debris-flow events on alluvial fans and cones remains scarce, although it is widely accepted that such knowledge is of crucial importance for the assessment of hazards, mitigation of risks, and land-use planning.

Archival records on the occurrence of past events are often fragmentary or even completely missing. Modern methods of historical dating of past debris-flow and flood events such as dendrochronology, radiocarbon dating, lichenometry and many more can provide valuable insights into past process activity and thus add key detail to the historical record.

Since the frequency and magnitude of these scenarios have a large impact on the calculated risk, dating of past events are of pivotal interest for risk analyses. The superposition of breccias on conglomerates implies that tributary debris-flow fans prograded from the valley margin towards the centre. Further downstream, the classical approach of palaeoflood hydrology Kochel and Baker utilizes geomorphic indicators such as overbank sediments, silt lines and erosion features of floods along a river e.
