Abstract Tide gauge water levels are commonly used as a proxy for flood incidence on land. These proxies useful projecting how sea‐level rise (SLR) will increase the frequency of coastal flooding. However, tide gauges do not account land‐based sources flooding and therefore thresholds derived from them likely underestimate current future Here we present new sensor framework measuring floods that captures both subterranean contributions to The low‐cost, open‐source consists storm drain level...
Abstract Many barrier islands and spits (collectively, “barriers”) throughout the world are highly developed. As low‐lying, sandy coastal landforms, systems naturally reshaped by processes associated with storms sea‐level rise (SLR). The resulting landscape changes threaten development, in response, humans employ defensive measures that physically modify geometry to reduce relatively short‐term risk. These include construction of large dunes, emplacement beach nourishment, removal washover....
Predicting coastal infrastructure reliability during hurricane events is important for risk-based design and disaster planning, including delineating viable emergency response routes. Previous research has focused on either vulnerability to sea-level rise flooding, or the impact of changing sea level landforms surge dynamics. This paper represents a multidisciplinary effort provide an integrative model combined impacts rise, landscape changes, flooding highway bridges—the only access points...
Abstract Nearshore hydro- and morphodynamic data were collected during a field experiment under calm conditions, moderate storm conditions with dune erosion in the collision regime. The was conducted on Sand Engine near Kijkduin, Netherlands, from October 18, 2021, to January 7, 2022. Two artificial unvegetated dunes constructed just above high water line measure impacts higher levels waves. During experiment, three storms occurred that resulted significant of both dunes. hydrodynamic...
Abstract Barrier islands and spits tend to migrate landward in response sea‐level rise through the storm‐driven process of overwash, but overwash flux depends on height frontal dunes. Here, we explore this fundamental linkage between dune dynamics barrier migration using new model Barrier3D. Our experiments demonstrate that discontinuous retreat is a prevalent behavior can arise directly from bistability foredune height, occurring most likely when storm return period characteristic time...
Abstract Classifying images using supervised machine learning (ML) relies on labeled training data—classes or text descriptions, for example, associated with each image. Data‐driven models are only as good the data used training, and this points to importance of high‐quality developing a ML model that has predictive skill. Labeling is typically time‐consuming, manual process. Here, we investigate process labeling data, specific focus coastal aerial imagery captured in wake hurricanes...
Inundation of coastal stormwater networks by tides is widespread due to sea-level rise (SLR). The water quality risks posed tidal rising up through infrastructure (pipes and catch basins), out onto roadways, back receiving bodies poorly understood but may be substantial given that are a known source fecal contamination. In this study, we (a) documented temporal variation in concentrations
Abstract Developed barrier systems (barrier islands and spits) are lowering narrowing with sea‐level rise (SLR) such that habitation will eventually become infeasible or prohibitively expensive for most communities in its current form. Before reaching this state, choices be made to modify the natural built environment reduce relatively short‐term risk. These likely vary substantially even along same developed system as these landscapes rarely uniformly managed alongshore. Building on results...
Hurricanes threaten the petroleum industry in United States and are expected to be influenced by climate change. This study presents an integrated framework for hurricane risk assessment of infrastructure under changing climatic conditions, calculating terms monetary loss. Variants two synthetic probabilistic storms one historical storm (Hurricane Ike) simulated using SWAN+ADCIRC model, representing a range potential scenarios impacts on forward speed sea-level rise given uncertainties...
Infragravity (IG) waves are expected to contribute significantly coastal flooding and sediment transport during hurricane overwash, yet the dynamics of these low-frequency impact remain poorly documented understood. This paper utilizes hydrodynamic measurements collected Hurricane Harvey (2017) across a low-lying barrier-island cut (Texas, U.S.A.) sea-to-bay directed flow (i.e., overwash). IG were observed propagate island for period five hours, superimposed on depth modulated by very-low...
Abstract Meteotsunami waves can be triggered by atmospheric disturbances accompanying tropical cyclone rainbands (TCRs) before, during, and long after a (TC) makes landfall. Due to paucity of high‐resolution field data along open coasts during TCs, relatively little is known about the forcing that generate resonantly amplify these ocean waves, nor their coastal impact. This study links measurements sea level air pressure from Hurricane Harvey (2017) with numerical model assess potential for...
Developed barrier systems (barrier islands and spits) are lowering narrowing with sea-level rise (SLR) such that habitation will eventually become infeasible or prohibitively expensive in its current form. Before reaching this state, communities make choices to modify the natural built environment reduce relatively short-term risk. Simulations conducted using a new coupled modeling framework show that, over decades centuries, measures protect roadways alter physical characteristics of ways...
Few datasets exist of high-frequency, in situ measurements storm overwash, an essential mechanism for the subaerial maintenance barrier islands and spits. Here we describe a new sensor platform measuring bed-level change estimating overwash inundation depths. Our MeOw (Measuring Overwash) stations consist two ultrasonic distance sensors, microprocessor board, camera are capable withstanding impacts large events, can be left unattended to collect data months years, relatively inexpensive....
