We present a case study of the potential impact on hurricane storm surge due to deepening the Corpus Christi Ship Channel through Aransas Pass in the region of Corpus Christi and Port Aransas, Texas. Our investigation is based on numerical mathematical models of the circulation of coastal water due to Hurricane Harvey and two synthetic hurricanes derived from Harvey. From the models, we ascertain maximum storm surge as well as elevation time series at critical locations in the study region. To

... ssess the effects of a deeper channel, we compare the model outputs for current and proposed future channels. The models indicate that the changes to maximum storm surge magnitude are small and in large portions of the study area the models indicate a reduction in surge magnitude. However, there are some local areas where the models results show an increase of up to 15 centimeters.
