Waves and water level setup during storms can create overwashing flows across barrier islands. Overwashing cause erosion, breaching, inlet formation, but their sediments also be deposited form washover fans. These widely different outcomes remain difficult to predict. Here we suggest that a breach develops when the sediment volume transported by exceeds subaerial volume. We simple analytical th...

The Ganges–Brahmaputra–Meghna Delta (GBMD) located in the head of Bay Bengal is regularly affected by severe tropical cyclones frequently. GBMD covers Bangladesh coast, which one most vulnerable areas world due to cyclone-induced storm surges. More than 30% total country’s population lives on coast. Hence, it crucial understand underlying processes that modulate surge height GBMD. A barotropic ...

Sandy beaches are the result of a dynamic interaction among physical conditions, biological processes and anthropic impact (essentially linked to natural resource direct or indirect exploitation). Monitoring health state coastal areas is fundamental tool for land-use management. Moreover, integrated sedimentological studies with multidisciplinary methodologies increasingly needed. This study ai...

Hydropower is an important tool in the struggle for low-emission power production. In Nordic countries, hydropower operating conditions are expected to change and work more conjunction with intermittent This turn might increase amount of hydropeaking events reaches downstream plants. The current investigates influence highly flexible, high-frequency on hydrodynamics reach. By quantifying four d...

The existence of the Mississippi River (MR) and Tributaries’ levees in coastal Louisiana could block storm surge cause setup adjacent basins. In order to reduce amplification caused by these barriers, one possible solution is build “floodways” through mainstem MR allow during tropical events cross. primary purpose this study examine if floodways/openings can help Using Hurricane Isaac (2012) as...

The coastal sediment budget is an essential tool to understand erosion/accretion patterns along coastlines and predict future changes. This work one of the first approaches a study in cuspate shoreline covering whole embayment-spit system. Taking this into consideration, aims estimate main longshore transport propose conceptual model regional lagoon (Lagoa dos Patos-Brazil), while also analyzin...

Abstract This study investigates the sensitivity of Calcasieu Lake estuarine region to channel deepening in southwest Louisiana USA. We test hypothesis that depth increase a navigational an results amplification inland penetration storm surge, thereby increasing flood vulnerability region. run numerical experiments using Delft3D modeling suite (validated with observational data) different histo...
