Sinuous patterns traced by fluid flows are a ubiquitous feature of physical landscapes on Earth, Mars, the volcanic floodplains Moon and Venus, other planetary bodies. Typically discussed as consequence migration processes in meandering rivers, sinuosity is also expressed channel types that show little or no indication meandering. Sinuosity sometimes described “inherited” from preexisting morphology, which still does not explain where inherited came from. For phenomenon so universal...
The concept of resilience has taken root in the discourse environmental management, especially regarding Building with Nature strategies for embedding natural physical and ecological dynamics into engineered interventions developed coastal zones. Resilience is seen as a desirable quality, management policy practice are increasingly aimed at maximising it. Despite its ubiquity, remains ambiguous poorly defined contexts. What resilience? And what does it mean settings where have been...
Abstract Sea‐level rise along low‐lying coasts of the world's passive continental margins should, on average, drive net shoreline retreat over large spatial scales (>10 2 km). A variety natural physical factors can influence trends erosion and accretion, but in recent rates change U.S. Atlantic Coast reflect an especially puzzling increase not erosion. plausible explanation for apparent disconnect between environmental forcing response is application, since 1960s, beach nourishment as...
Stabilization of riverbanks by vegetation has long been considered necessary to sustain single-thread meandering rivers. However, observation active in modern barren landscapes challenges this assumption. Here, we investigate a globally distributed set rivers with varying riparian densities, using satellite imagery and statistical analyses meander-form descriptors migration rates. We show that enhances the coefficient proportionality between channel curvature rates at low curvatures, effect...
Tropical forests are the only forest biome to have experienced increased rates of loss during past decade because global demands for food and biofuels. The implications such extensive clearing on dynamics tropical river systems remain relatively unknown, despite significant progress in our understanding role trees riverbank stability. Here, we document deforestation corresponding average annual erosion along freely meandering Kinabatangan River Sabah, Malaysia, from Landsat satellite imagery...
Abstract Beach nourishment, a method for mitigating coastal storm damage or chronic erosion by deliberately replacing sand on an eroded beach, has been the leading form of protection in United States four decades. However, investment hazard can have unintended consequence encouraging development places especially vulnerable to damage. In comprehensive, parcel‐scale analysis all shorefront single‐family homes state Florida, we find that houses nourishing zones are significantly larger and...
Abstract Deliberate, real‐time human interventions into geomorphic processes are a phenomenon that no off‐the‐shelf numerical model of morphodynamics is built to capture. We suggest active, responsive affect sediment transport during major storm events be included in evolving efforts change.
Resilience is widely seen as an important attribute of coastal systems and, a concept, increasingly prominent in policy documents. However, there are conflicting ideas on what constitutes resilience and its operationalisation overarching principle management remains limited. In this paper, we show how to flood erosion hazard could be measured applied within processes, using England case study. We define pragmatically, integrating presently disparate set objectives for areas. Our definition...
Abstract Given the inevitability of sea-level rise, investigating processes human-altered coastlines at intermediate timescales years to decades can sometimes feel like an exercise in futility. Returning big picture and long view feedbacks, emergent dynamics, wider context, here we offer 10 existential questions for research into human–coastal coupled systems.
Abstract Sinuous channels wandering through coastal wetlands have been thought to lack lateral‐migration features like meander cutoffs and oxbows, spurring the broad interpretation that tidal fluvial meanders differ morphodynamically. Motivated by recent work showing similarities in planform dynamics between meandering channels, we analyzed neck from diverse environments worldwide, show are widespread. Their perceived paucity stems pronounced channel density hydrological connectivity...
Abstract. Developed coastal areas often exhibit a strong systemic coupling between shoreline dynamics and economic dynamics. "Beach nourishment", common erosion-control practice, involves mechanically depositing sediment from outside the local littoral system onto an actively eroding to alter morphology. Natural sediment-transport processes quickly rework newly engineered beach, causing further changes that in turn affect subsequent beach-nourishment decisions. To limited extent this...
Abstract Sinuous channel networks dissecting tidal wetlands are highly dynamic and often abandoned as a result of captures meander cutoffs. However, the effects dynamics on blue carbon fluxes remain unclear. Analyses channels in Venice Lagoon (Italy) demonstrate that they take up organic at significantly faster rates than neighboring marshes. This is because, despite slightly lower sediment density, yield higher vertical accretion owing to topographic accommodation reduced flow velocities,...
Using shoreline change measurements of two oceanside reaches the North Carolina Outer Banks, USA, we explore an existing premise that on a sandy coast is self‐affine signal, wherein patterns are scale invariant. Wavelet analysis confirms mean variance (spectral power) can be approximated by power law at alongshore scales from tens meters up to ∼4–8 km. However, possibility relationship does not necessarily reveal unifying, scale‐free, dominant process, and deviations scaling kilometers may...
A worldwide increase in large‐scale land acquisitions over the past decade has been described as a global rush for access to natural resources. ‘Land grabbing’ is dynamic of land‐use change that can enable especially rapid environmental transformations across vast spatial scales. New scholarship beginning address these deals terms their implications social and political systems, but exploitative uses also leave legacies physical landscapes. Historical precedents from around world, including...
Abstract Overwash is a physical process of coastal sediment transport driven by storm events and essential to landscape resilience in low‐lying barrier environments. This work establishes comprehensive set scaling laws for overwash morphology: unifying quantitative descriptions with which compare features their morphological attributes across case examples. Such also help relate other morphodynamic phenomena. Here morphometric data from experiment are compared natural examples features. The...
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...
Given incontrovertible evidence that humans are the most powerful agents of environmental change on planet, research has begun to acknowledge and integrate human presence activity into updated descriptions world’s biomes as “anthromes”. Thus far, a classification system for anthromes is limited terrestrial biosphere. Here, I present case consideration validity coastal anthromes. Every environment Earth subject direct indirect modification disturbance. Despite legacy, ubiquity, pervasiveness...
