Fluvial geomorphology and paleofloods in arid central Australia
… is composed of erodable paleoflood sediments. Paleofloods greater than observed historical floods flowed from gorges through the MacDonnell Ranges as sheet floods depositing transverse bar fields, at H.l channels flowed across fans forming braided 12 km splays that include large longitudinal …

Relationships Between Snake River Paleofloods, Occupational Patterns and Archaeological Preservation at Redbird Beach Archaeological Site in Lower Hells Canyon, Idaho
<p>The Snake River basin drains 282,000 km<sup>2</sup> of the northwestern U.S. and is the largest tributary to the Columbia River. Redbird Beach, an archaeological site located in the lower Hells Canyon reach of the Snake River, contains extensive vertical exposures of archaeological materials …

A small look at the big picture: linking geopotential height anomalies to paleofloods on the Snake River, Idaho and Oregon
<p>A combined paleoflood and flood hydroclimatology study on the Snake River in Idaho and Oregon suggests a link between floods and patters of geopotential height anomalies over the North Pacific Ocean. Examination of the paleoflood record in two 4-m (12 ft) tall terraces along the Hells Canyon …

Paleoflood Record Reconstruction at an Archaeological Site on the Owyhee River, Southeastern Oregon
… System modeling of the 1993 flood and several paleofloods suggests that the 1993 flood (1600 m<sup>3</sup>/s) was one of the largest floods to have occurred on the Owyhee River in at least the last 1400 years, and perhaps in the last 2800 years.</p> <p>Artifacts found to date in the profiles …

Exploring Long-Term Flood Variability in the Lower French Broad River Using Fluvial Paleoflood Hydrology
… were used to infer the size of past floods (paleofloods) based on peaks in coarse sand volume referred to as "flood peaks". A Bayesian age-depth model using long optical stimulated luminescence dating of quartz and radiocarbon-dated wood from distinct flood units was used to estimate …

Late Holocene Paleoflood Hydrology of the Snake River in the Lower Hells Canyon, Idaho
… Idaho. The sites contain evidence of up to 34 paleofloods within the last 1700 years. Stratigraphic breaks, soils, and in-situ plant or archaeological materials demarcate distinct layers that represent discrete paleoflood events. Radiocarbon dates from <em>in-situ</em> and transported charcoal …

Mid- to Late Holocene flood reconstruction from two varved sediment profiles of pre-alpine Lake Ammersee (Southern Germany)
Climate is the principal driving force of hydrological extremes like floods and attributing generating mechanisms is an essential prerequisite for understanding past, present, and future flood variability. Successively enhanced radiative forcing under global warming enhances atmospheric …

A 7000 yr runoff chronology from varved sediments of Lake Mondsee (Upper Austria)
The potential increase in frequency and magnitude of extreme floods is currently discussed in terms of global warming and the intensification of the hydrological cycle. The profound knowledge of past natural variability of floods is of utmost importance in order to assess flood risk for the future. …
