2019 The Authors The authors regret to make the following corrections for the estimation of freshwater export rate (Qf) and total freshwater load into Galveston Bay due to Hurricane Harvey. In estimating the cross-sectional average normal velocity at the bay entrance (Section 2.3 in the published article), we mistakenly used the velocity measured at buoy g06010 (near the mouth of the bay) as the surface velocity while the velocity was actually measured at 6 m deep (i.e., mid-depth), which resulted in underestimation of F and thus Qf. With the mid-depth observed velocity, following exactly the same methodology as in published article, we obtained a new relationship between current at buoy g06010 and cross-sectional average normal current (updated Fig. 3). The freshwater export rate during Hurricane Harvey and the following month was recalculated using this new relationship (updated Fig. 8). The maximum freshwater export rate now is 28,000 m3/s (was 26,000 m3/s in the published article); the total freshwater load is 14.0 109 m3 (was 11.1 109 m3 in the published article); the input along the coastline (others) is increased to 6.63 109 m3 from 3.73 109 m3 (updated Table 2). These estimates provide very important information with respect to the influence of Hurricane Harvey and would be valuable for other researchers. Therefore, we believe it is necessary to make this corrigendum. [Figure presented] Updated Fig. 3. Relationship between current at the buoy g06010 station and cross-section average normal current, based on hourly numerical model results in 20072008, showing a quadratic polynomial regression (bold solid line) and its 95th confidence interval (dashed lines). [Figure presented] Updated Fig. 8. Freshwater export rate estimated at the bay entrance using the freshwater fraction method, with the bold line indicating the subtidal component. Grey shading indicates the period of August 2630, during which heavy Harvey precipitation occurred.
