# Study_Name:  A 2000 year long seasonal record of floods in the southern
  European Alps, Lake Ledro, Northern Italy
# Investigators:
# Wirth,S.B.; Gilli,A.; Simonneau,A.; Ariztegui,D.; Vannière,B.; Glur,L.;

# Description_and_Notes
Description: This dataset contains ages and thicknesses of individual flood
# layers ('thickness' files) as well as 30-year moving sums of flood events
# ('counts' files) for all seasons. The dating of the flood layers is based
# on varve counting and the age-model error of ±2.5% is estimated based on
# the comparison with five radiocarbon ages.

# Abstract: Knowledge of past natural flood variability and controlling
# climate factors is of high value since it can be useful to refine
# projections of the future flood behavior under climate warming. In this
# context, we present a seasonally resolved 2000 year long flood frequency
# and intensity reconstruction from the southern Alpine slope (North Italy)
# using annually laminated (varved) lake sediments. Floods occurred
# predominantly during summer and autumn, whereas winter and spring events
# were rare. The all-season flood frequency and, particularly, the
# occurrence of summer events increased during solar minima, suggesting
# solarinduced circulation changes resembling negative conditions of the
# North Atlantic Oscillation as controlling atmospheric mechanism.
# Furthermore, the most extreme autumn events occurred during a period of
# warm Mediterranean sea surface temperature. Interpreting these results in
# regard to present climate change, our data set proposes for a warming
# scenario, a decrease in summer floods, but an increase in the intensity of
# autumn floods at the South-Alpine slope.
