Reconstructing Paleoflood Occurrence and Magnitude from Lake Sediments

Quaternary, 2022
Lake sediments are a valuable archive to document past flood occurrence and magnitude, and their evolution over centuries to millennia. This information has the potential to greatly improve current flood design and risk assessment approaches, which are ...

Mega-floods over the past 30,000 years in western yunnan, southwest China [PDF]

Scientific Reports
Global warming has been leading to a significant increase in the frequency and intensity of extreme rainfall events, however, few paleoflood records hinder our understanding of its long-term patterns and underlying mechanisms.

Sedimentary Records of Paleoflood Events in the Desert Section of the Upper Yellow River Since the Late Quaternary

Atmosphere
The frequency and intensity of paleofloods reveal long-term hydrological changes and their responses to regional climate variations. This study focuses on sediment core HDZ04 from the desert section of the upper Yellow River, analyzing sediment grain ...

Demarcating paleoflood repositories using documentary evidence and flood geomorphic landforms

Quaternary Science Advances
A reconstruction of paleoflood stages reflects the magnitude and frequency of historic floods. Sediment-filled landforms store centuries-old paleoflood data, allowing examination of past events, though river changes and human activities can obscure these

Geochemistry of a paleo-oxbow lake sediments and its implications for the late Holocene extreme overbank flooding history of the Yellow River within the Zoige Basin, NE Tibetan Plateau

Frontiers in Earth Science, 2023
Paleo-oxbow lake sediments can provide archives to reconstruct paleo-channel evolution and flooding history of the river. Multi-proxy approaches including detailed sediment stratigraphy, sedimentology and geochemistry have been implemented in a high ...

An improved method for paleoflood reconstruction from core sediments in the upper Yellow River

Frontiers in Earth Science, 2023
Fluvial deposits represent a sedimentary archive of paleohydrological information, which can be utilized to reconstruct unrecorded floods. A multi-index (grain size, end-member model, and geochemistry elements) approach of core sediments from the upper ...

Multi-Proxy Records of Late Holocene Flood Events From the Lower Reaches of the Narmada River, Western India

Frontiers in Earth Science, 2021
Analyses of a fluvial sedimentary sequence from the lower reaches of the Narmada River establish a record of rhythmic cycles of sediment facies that represent floods during the late Holocene.

Sedimentary records and chronology of the late Pleistocene overbank flooding in the Yellow River source area, NE Tibetan Plateau

Frontiers in Earth Science, 2022
Paleohydrological investigations were carried out in the Yellow River source area on the northeast (NE) Tibetan Plateau. During our fieldwork investigations, two units of overbank flood deposits (OFD) were found in the Maqu-Kesheng reach. These OFD units

New flood frequency estimates for the largest river in Norway based on the combination of short and long time series [PDF]

Hydrology and Earth System Sciences, 2020
The Glomma River is the largest in Norway, with a catchment area of 154 450 km2. People living near the shores of this river are frequently exposed to destructive floods that impair local cities and communities.
