“…The formation of paleosols in WRB alluvium between 1.5 ka and 600 a indicates periods of fluctuating hydroclimate similar to the timing of stabilization and soil formation recorded in ACT paleosols by Rawling et al (2003). Similar episodes of climate-driven alluvial aggredation and incision during the Holocene have been reported in other studies from the Great Plains, including southwest Nebraska (Daniels, 2008;Daniels and Knox, 2005), Kansas (Arbogast and Johnson, 1994), and South Dakota (Harden et al, 2015).…”

“…This involves a systematic probability-based analysis of geochronologically dated fluvial units (Jones et al, 2015a), and it provides for a synthesis of the growing spatial coverage and increasing chronological precision of fluvial archives for reconstructing past river responses to environmental changes (Benito et al, 2015;Macklin et al, 2006). Metaanalysis has now been employed in regional analyses of extreme flood events and fluvial change or stability in river systems in many different parts of the world, including Northern Europe (Macklin and Lewin, 2003;Toonen et al, 2017), the Mediterranean region (Benito et al, 2015;Macklin et al, 2006;Rossato et al, 2015), North Africa (Macklin et al, 2015), the southwestern and central USA (Harden et al, 2010;Harden et al, 2015), and the northeastern Tibet Plateau (Stauch, 2016).…”

Given its singular importance for water resources in the southwestern USA, the Upper Colorado River Basin (UCRB) is remarkable for the paucity of its conventional hydrological record of extreme flooding. Short-term record-based flood frequency analyses lead to very great aleatory uncertainties about infrequent extreme flood events and their climate-driven causal associations. This study uses paleoflood hydrology to examine a small portion of the underutilized, but very extensive natural record of Holocene extreme floods in the UCRB. We perform a meta-analysis of 82 extreme paleofloods from 18 slack water deposit sites in the UCRB to show linkages between Holocene climate patterns and extreme floods. The analysis demonstrates several clusters of extreme flood activity: 8040–7960, 4400–4300, 3600–3460, 2900–2740, 2390–1980, 1810–720, and 600–0 years BP. The extreme paleofloods were found to occur during both dry and wet periods in the paleoclimate record. When compared with independent paleoclimatic records across the Rocky Mountains and the southwestern USA, the observed temporal clustering pattern of UCRB extreme paleofloods shows associations with periods of abruptly intensified North Pacific-derived storms connected with enhanced variability of El Niño. This approach demonstrates the value of creating paleohydrological databases and comparing them with hydro-climatic proxies in order to identify natural patterns and to discover possible linkages to fundamental processes such as changes in climate.

“…Paleoflood records of high-magnitude events from the upper Missouri River basin (Figure 4c) and the upper Mississippi River (Figure 4d) exhibit coherent trends, and show an interval of low flood frequency between circa CE 500 and 1000 that corresponds to the most depleted δ 2 H wax values of our record (Figure 4f), while enrichment of δ 2 H wax before CE 500 and after CE 1000 is associated with increased flood frequency. Flooding did not decline as temperatures cooled following the Medieval era, implying that warm-season (Forman et al, 2008;Hanson et al, 2009Hanson et al, , 2010; (c) slackwater paleoflood deposits from the Black Hills, upper Missouri River basin (Harden et al, 2015); (d) upper Mississippi River floodplain paleoflood deposits (Munoz et al, 2015); (e) brGDGT-temperature records; and (f) δ 2 H wax from Horseshoe Lake, Illinois (this study).

Floods and droughts in the Mississippi River basin are perennial hazards that cause severe economic disruption. Here we develop and analyze a new lipid biomarker record from Horseshoe Lake (Illinois, USA) to evaluate the climatic conditions associated with hydroclimatic extremes that occurred in this region over the last 1,800 years. We present geochemical proxy evidence of temperature and moisture variability using branched glycerol dialkyl glycerol tetraethers (brGDGTs) and plant leaf wax hydrogen isotopic composition (δ 2 H wax) and use isotope-enabled coupled model simulations to diagnose the controls on these proxies. Our data show pronounced warming during the Medieval era (CE 1000-1,600) that corresponds to midcontinental megadroughts. Severe floods on the upper Mississippi River basin also occurred during the Medieval era and correspond to periods of enhanced warm-season moisture. Our findings imply that projected increases in temperature and warm-season precipitation could enhance both drought and flood hazards in this economically vital region. Plain Language Summary The Mississippi River basin is an economically vital region for industry and agriculture, but it is prone to disruptive flooding and drought. Here we use organic molecules preserved in a lake sediment core to reconstruct the temperature and seasonal moisture patterns of the last 1,800 years. Our reconstruction shows that the Medieval period (ca. CE 1000-1,600) was relatively warm and that warmer temperatures in this region are associated with increased frequencies of severe droughts and floods. These findings generally support climate model projections of increasing drought and flood hazard in the Mississippi River basin as a result of anthropogenic climate change.
