Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,

Morphodynamics of a mesotidal, exposed, low tide terrace beach (Faro, southern Portugal)
A field assessment of microtopographic changes and disturbance depth was carried out during a tidal cycle at Faro beach, southern Portugal. This mesotidal beach presents a well developed low tide terrace, wide and flat (tan ß = 0.02), and an important ...

Extremes in dune preservation: controls on the completeness of fluvial deposits [PDF]
Understanding sedimentary preservation underpins our ability to interpret the ancient sedimentary record and reconstruct palaeoenvironments and palaeoclimates.

Abstract This study examined the spatiotemporal variability in geotechnical properties of beach cusp sediments on a sandy beach and tested if such variability can be used for cusp monitoring from satellite imagery. Specifically, sediment properties (including moisture content (w), relative density (Dr), sediment strength (QSBC) and friction angle (ϕ ...

Experimental distributive fluvial systems: Bridging the gap between river and rock record
A debate has called into question as to which fluvial channel patterns are most widely represented in the stratigraphic record, with some advocating that distributive fluvial systems (DFS) predominate and others that a broad diversity of fluvial styles ...

Abstract Tides play a key role in regulating shelf‐sea environments, influencing sediment dynamics, habitat distribution, long‐term carbon burial, coastal hazards, and water quality, with important socio‐economic consequences. Yet the long‐term evolution of shelf sea tides in response to sea‐level change remains poorly understood. We have developed the

Graphical Abstract Abstract Effective sediment management in reservoir–river coupled systems remains a global challenge due to the conflicting objectives of sediment evacuation from reservoirs and deposition reduction in downstream reaches. This study proposed a physics‐based modeling framework oriented to a reservoir–river coupled system, which ...

Effects of tropical cyclone Jasper at Low Island, northern Great Barrier Reef
Tropical cyclones (TC) can produce waves and water levels that markedly reshape sand cay shorelines. TC Jasper (December 2023) passed near Low Island (Low Isles, Northern Great Barrier Reef [GBF]) as a category 2 storm.

The analysis of aerial photographs (of several missions) coupled with the study of heavy minerals made it possible to show the shoreline changes, to reconstitute the dynamics of the various sedimentary environments of the Saïdia littoral and to underline

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream
Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...
