  • Extreme event in the last 200 years in the Upper Vistula Basin : their palaeohydrological implications
  • Exceptional event ; Hydrology ; Palaeogeography ; Palaeohydrology ; Poland ; Precipitation ; Upper valley ; Wisła
  • To provide characteristics of present-day extreme events which may serve as a key to better recognition of past hydrological changes, the upper Vistula basin was taken as an example. The observations are mainly related to last 100-150 years
  • of events. Only first half of 19-th century, the last phase of the Little Ice Age shows higher frequency of extreme events. This study shows also a great regional diversity in effects of extreme events. Therefore all recontruction of the humid phases during

  • A reassessment of U-Th and C 14 ages for Late-Glacial high-frequency hydrological events at Searles Lake, California
  • The AA. discuss the timing of the last, and most dramatic, pluvial event recorded in Lake Lahontan and Searles Lake, and of distinct dry periods recorded as evaporite layers in the Searles basin. The last major pluvial events in these closed basins
  • happened during the transition interval between the last iceberg discharge event Heinrich 1, (14 500 C 14 yr B.P.) and the Bølling-Allerød warming (12 800 C 14 yr B.P.).

  • A large California flood and correlative global climatic events 400 years ago
  • and 1610, the AA. explore possible climatic connections with extreme events elsewhere in the region and around the globe.

  • Modelling the geomorphological impact of climatic variability and extreme events in a semi-arid environment
  • properties and process is apparent in the results. The A. concludes with the observation that the majority of significant soil erosion events in Castilla La Mancha (CLM) occur as a result of extreme precipitation events rather than slow progressive land

  • Exceptional event ; Holocene ; Hydrometeorology ; Palaeo-environment ; Palaeoclimatology ; Precipitation
  • During the Holocene were identified episodes with higher frequency of extreme events like heavy downpours, continuous rains, rainy phases, rapid decades. All of them are reflected in sedimentary sequences, in relief and biotic changes
  • . The A. describes more in detail the effects of climatic conditions during the Little Ice Age and 20-th century, what helps to identify similar episodes during the whole Holocene. Their common feature is the clustering of extreme events connected mainly with cooler

  • Correlation of Late-Pleistocene lake-level oscillations in Mono Lake, California, with North Atlantic climate events
  • Lake occurred during Heinrich events H1, H2, and H4. These results enforce the concept that relatively dry-wet oscillations in the climate of the Great Basin of the western United States occurred at approximately the same times as cold-warm oscillations

  • Spatial variability of floodplain sedimentation at the event scale in the Rhine-Meuse delta, the Netherlands
  • This article addresses spatial variability of contemporary floodplain sedimentation at the event scale. Measurements of overbank deposition were carried out using sediment traps on 11 floodplain sections along the rivers Waal and Meuse
