“…Sea level rise, perhaps surprisingly, does not occur uniformly as it would if water was added to a bathtub. Currents and wind play a definite role, and whether a land mass is subsiding (as along much of the Gulf coast) or rebounding from the pressure of glaciers (as in Alaska and other northern locations) will make a difference (Seitz et al, 2023). Tools needed for this type of analysis include storm surge models that can characterize wave height and surge-related flooding under a variety of tidal, wind, and sea level rise scenarios (Elahi et al, 2023;Makris et al, 2023;Mathew and CA, 2023).…”

Water is often referred to as our most precious resource, and for a good reasondrinking water and wastewater services sustain core functions of the critical infrastructure, communities, and human life itself. Our water systems are threatened by aging infrastructure, floods, drought, storms, earthquakes, sea level rise, population growth, cyber-security breaches, and pollution, often in combination. Marginalized communities inevitably feel the worst impacts, and our response continues to be hampered by fragmented and antiquated governance and management practices. This paper focuses on the resilience of water sector (drinking water, wastewater, and stormwater [DWS]) to three major hazards (Sea-Level Rise, Earthquake, and Cyberattack). The purpose of this paper is to provide information useful for creating and maintaining resilient water system services. The term resilience describes the ability to adapt to changing conditions and to withstand and recover from disruptions. The resilience of DWS systems is of utmost importance to modern societies that are highly dependent on continued access to these water sector services. This review covers the terminology on water sector resilience and the assessment of a broad landscape of threats mapped with the proposed framework. A more detailed discussion on two areas of resilience is given: Physical Resilience, which is currently a major factor influencing disruptions and failures in DWS systems, and Digital Resilience, which is a rapidly increasing concern for modern infrastructure systems. The resilience of DWS systems should be considered holistically, inclusive of social, digital, and physical systems. The framework integrates various perspectives on water system threats by showcasing interactions between the parts of the DWS systems and their environment. While the challenges of change, shock and stresses are inevitable, embracing a social-ecological-technical system-of-systems and whole-life approach will allow us to better understand and operationalize resilience. Impact statementServices provided by water lifeline infrastructure (e.g., drinking water, wastewater, and stormwater [DWS] systems) are critical to modern societies. However, stresses from aging and external threats (e.g., sea level rise, floods, earthquakes) on existing DWS systems and the current practice of siloed governance and management of DWS systems have worsened the vulnerabilities in many communities, especially in the marginalized ones. This paper presents a new framework on managing the resilience of DWS systems in the water sector to three major hazards (Sea-Level Rise, Earthquake, and Cyberattack). The new framework embraces a social-ecological-technical system-of-systems approach and a whole-life approach to allow communities to better understand and operationalize short-term to long-term resilience in their DWS systems. The framework also endorses the integration of the goals of sustainability and resilience for overcoming global water challenges, and provides insights via case studies on how...

“…The capacity of coastal wetlands to sustain their position within the tidal envelope is key to resiliency under conditions of climate change [1,2]. As these environments provide substantial habitat value and ecosystem function [3][4][5], myriad investigations have been conducted over the years to quantify ongoing and future risks to their resiliency under conditions of a changing climate and, in particular, accelerating sea level rise. Initially, these investigations focused on observations of ecosystem migration [6,7] and vertical sediment accumulation [8][9][10].…”

This investigation evaluated two fundamental assumptions of wetland inundation models designed to emulate landscape evolution and resiliency under conditions of sea level rise: that they can (1) migrate landward at the same rate as the transgressing shoreline and (2) immediately replace the plant community into which they are onlapping. Rates of wetland (e.g., marsh, mangrove) migration were culled from 11 study areas located in five regions of focus: Delaware Bay, Chesapeake Bay, Pamlico Sound, South Florida, and Northwest Florida. The average rate of marsh migration (n = 14) was 3.7 m yr−1. The average rate of South Florida mangrove migration (n = 4) was 38.0 m yr−1. The average rate of upland forest retreat (n = 4) was 3.4 m yr−1. Theoretical rates of shoreline transgression were calculated using site-specific landscape slope and scenario-based NOAA sea level rise elevations in 2050. Rates of shoreline transgression over the marsh landscape averaged 94 m yr−1. The average rate of shoreline transgression in the mangrove-dominated areas of South Florida was 153.2 m yr−1. The calculated rates of shoreline transgression were much faster than the observed horizontal marsh migration, and by 2050, the offset or gap between them averaged 2700 m and ranged between 292 and 5531 m. In South Florida, the gap average was 3516 m and ranged between 2766 m and 4563 m. At sites where both horizontal marsh migration and forest retreat rates were available, the distance or gap between them in 2050 averaged 47 m. Therefore, the results of this study are inconsistent with the two fundamental assumptions of many wetland inundation models and suggest that they may overestimate their resilience under conditions of 21st century accelerating sea level rise.
