Sedimentology and paleohydrology of glacial-lake outburst deposits in southeastern Saskatchewan and northwestern North Dakota

Catastrophic flooding from Glacial Lake Wisconsin

“…analogues to illustrations given in Barnes (1967) and consistent with paleohydraulic reconstructions in nearby environments (e.g., Matsch, 1983;Lord and Kehew, 1987;Becker, 1995). Interpolated cross sections were added at 200-m intervals; these did not alter the model output per se, but were included to facilitate the calibration.…”

Streamlined islands and the English Channel megaflood hypothesis

“…Along the palaeo-margin of the Laurentide ice sheet in central and eastern North America, the floodwater 566 pathways show largely erosional streamlined islands, with only limited depositional gravel bars (Lord and 567 Kehew, 1987;Kehew et al, 2009). Whilst the similarity with the English Channel is stronger than the 568 previously described examples; there are clear differences in the number and distribution of the erosional 569 remnants.…”

Reconstructing an extreme flood from boulder transport and rainfall–runoff modelling: Wadi Isla, South Sinai, Egypt

“…Lord and Kehew (1987) used this method to estimate the depth of a glacial lake outburst flood; the estimated depth was subsequently used in the Manning equation to estimate velocity and discharge. Lord and Kehew (1987) speculated that this procedure overestimated depth because of the hyperconcentrated character of the flows, a condition that does not apply to the Wadi Isla floods. Kehew and Teller (1993) used a variant of the Church (1978) method proposed by Komar (1987Komar ( , 1989 to account for selective entrainment of large clasts from a deposit of mixed sizes.…”
