In ‘Denudation rates of a subequatorial orogenic belt based on estimates of sediment yields: evidence from the Paleozoic Appalachian Basin, USA’, originally published in Basin Research 29, 2–15 (2017), http://doi.org/10.1111/bre.12162, the authors have brought the following to our attention:

Discharge values in Table 2 of this manuscript are overestimated by an order of magnitude, due to an error in unit conversion. A corrected version of Table 2 is included below.

^a 0.67 correction factor of Paola and Borgman (1991) applied to maximum measured channel element thickness.
^b Empirical equations of Bridge and Tye (2000) and Allen (1970) applied to mean cross‐bed set thickness.
^c Koppen climate symbols are as follows: Af, Tropical rainforest; Am, Tropical monsoon; Aw, Tropical savannah; BW, Arid Desert; BS, Arid Steppe – subscripts h and k refer to hot and cold, respectively; Cs, Temperate dry summer; Cw, Temperate dry winter; Cf, Temperate without dry season – subscripts a, b, and c refer to hot summer, warm summer, and cold summer, respectively; Ds, Cold dry summer; Dw, Cold dry winter; Df, Cold without dry season – subscripts a, b, c, and d refer to hot summer, warm summer, cold summer, and very cold winter, respectively; ET, Polar Tundra; EF, Polar Frost.
^d The coefficient (a) and exponent (b) are quoted in the original source and were computed for imperial units of measure; results have been converted to metric units.

While the main conclusions of the paper specifically concerning sediment yield and sediment load estimates, on which denudation rates are based, are not affected by this calculation error, the conclusions on the character of flows that supplied sediment to the basin require modification. The article originally concluded that hyperpycnal flows were rare to absent, whereas the corrected discharge estimates support occasional to frequent hyperpycnal flows. Therefore, Figure 8c in the original paper was incorrect. The corrected version of Figure 8 is below. This conclusion is consistent with the presence of some turbidite‐like deposits in the Pride Shale. Additionally, the revised discharge estimates now plot within the drainage area versus discharge envelope for modern rivers.

Estimates of Pride river system in terms of: (a) annual sediment load; (b) mean annual sediment yield; and (c) mean annual suspended sediment concentration in comparison to global database of modern rivers from Milliman & Farnsworth (2011). Part C compares results to the hyperpycnal‐flow frequency subdivision of Mulder & Syvitski (1995). Error bars in the y‐axis direction represent a range of durations for filling the depocentre; solid line and maxima represent estimated durations, whereas dashed line extending downward to the minima represents the maximum duration of the Pride Shale (400 kyr). The range in the x‐direction represent a range of catchment area estimates. The regions of favoured estimates are shown by the blue polygons.

尽管本文的主要结论（具体涉及基于剥蚀率的沉积物产量和沉积物负荷估算）不受此计算误差的影响，但有关将沉积物供应到流域的流量特征的结论仍需修改。该文章最初得出结论，很少会出现高脓血流量，而校正后的出院估计值支持偶尔出现高尿酸流量。因此，原始纸张中的图8c不正确。下面是图8的更正版本。这一结论与Pride页岩中存在一些类似浊石的沉积物是一致的。此外，修订后的流量估算现在绘制在流域内与现代河流的流量范围之间。
