2.5.2 Real case – Hurricane Harvey
Hurricane Harvey is one of the most destructive extreme weather events happened in this study area with damaging winds and urban flooding. The storm was stalled over the Houston region for one week with continuous falling of extreme rains to develop pluvial and fluvial flooding, compounded by costal surges. According to the precipitation estimates by gauges and radars, 1,539 mm maximum rainfall was observed and most locations in the study area recorded at least 760 mm rainfall, making it the wettest tropical cyclone on record. As a result, almost 25-30 percent of Harris Country was submerged during this event. Owing to the socioeconomic impact, a variety of flood simulations were conducted in this region (Chen et al., 2021; Dullo et al., 2021; Li et al., 2021b; Sebastian et al., 2021). The simulation in our study is conducted from 2017-08-26 to 2017-09-01, during which we did not vary model parameters between scenarios with and without re-infiltration. The parameter values are optimized from a previous study (Li et al., 2021b). The initial soil moisture states are obtained from the operational FLASH project (flash.ou.edu/new).
