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 …

Late Holocene Paleoflood Hydrology of the Snake River in the Lower Hells Canyon, Idaho
… inland Pacific Northwest, and a comprehensive paleoflood chronology on the mainstem of the river is key to identifying the frequency and magnitude of large prehistoric floods within the region. We examined and compared four sites of slackwater deposits along a 20-km reach of the Lower Hells …

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 …

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 …

Fluvial geomorphology and paleofloods in arid central Australia
… and chronology of the modern flood plain and paleoflood complexes, and discusses the geomorphic effects of high magnitude floods and the subsequent recovery and adjustment of the river. The Todd River has two kinds of flood plains: confined and relatively unconfined. Both have a complex …

Frequency analysis and two-dimensional simulations of extreme floods on a large watershed
… compare the flood frequency curve with gage and paleoflood data. A new channel mesh generator was developed to provide spatially-distributed channel geometry inputs to the TREX model. The channel geometry was defined using power functions for bank heights and channel widths based on field data …
