An Examination of Compound Flood Hazard Zones for Past, Present, and Future Low-Gradient Coastal Land-Margins

Abstract: Recent events worldwide demonstrate how coastal communities of integrated natural and human systems are exposed to hydrological and coastal flooding processes. Standard flood hazard assessment practices account independently for rainfall-runoff, tides, storm surge flooding and not the non-linear combination commonly defined as compound flooding. This research evaluates compound flood hazard zones for past, present, and future (c. 1890–2090) conditions of the Mississippi River Delta Plain (MRDP). The MRDP provi… Show more

“…Compound flooding in low-lying coastal areas is a recognized hazard that can be exacerbated by global warming (Hao and Singh, 2020;Santiago-Collazo et al, 2021;Gori et al, 2022;Hsiao et al, 2021;Ghanbari et al, 2021). A compound flooding hazard is derived from the interaction of storm surge penetration, riverine flooding, and intense rainfall over the areas (as the impact of extreme meteorological events) that coincide or nearly coincide (Bilskie and Hagen, 2018;Ikeuchi et al, 2017;Wahl et al, 2015).…”

“…There are various mechanisms driving compound flooding in low-lying urban coastal areas (Santiago-Collazo et al, 2019). Firstly, the water level increases with the tide, and the sea level rises due to climate change.…”

“…Hydraulic/hydrodynamic models have been used to identified transition zones during historical events (Eilander et al., 2022; Gori, Lin, & Smith, 2020; Stephens et al., 2022) and hypothetical scenarios based on past storms (Bilskie & Hagen, 2018; Santiago‐Collazo et al., 2021; Shen et al., 2019). At the catchment scale, hydraulic models such as the Hydrologic Engineering Center‐River Analysis System (HEC‐RAS) (HEC, 2002) provide robust estimates of along‐river water levels (Loveland et al., 2021).…”

“…For example, elevated coastal water levels can inhibit the efficient drainage of rainfall and river discharge to the ocean, leading to a backwater effect (Y. J. Zhang et al., 2020). The frequency and severity of compound flooding could increase in the future as a result of sea‐level rise (Naseri & Hummel, 2022; Santiago‐Collazo et al., 2021; Sweet & Park, 2014) and changes in tropical cyclones, which are projected to become more intense (Emanuel, 2005, 2013; Sobel et al., 2016) and wetter (Emanuel, 2017; Trenberth et al., 2018) with climate change. Thus, there is a recognized need to develop more comprehensive flood risk assessment approaches that integrate coastal, fluvial, and pluvial drivers (Herdman et al., 2018).…”
