Tidal bores, catastrophic flooding in Bangladesh, and the potential usefulness of causeways [PDF]
, 2006 Through discussion of the worldwide devastation that tidal bores can cause, author Priyanka Joseph, examines the causes and the possible solutions to prevent these destructive waves.

Effect of a large bed roughness on positive surge propagation in canals [PDF]
, 2016 In open channels and water supply canals, the brusque operation of control valves and gates may induce large unsteady flow motions called surges. To date, the literature has focused on the propagation of surges in smooth canals, ignoring the effects of ...

Sedimentary signatures of tidal bores: a brief synthesis [PDF]
Geo-Marine Letters, 2016 This article aims at presenting a brief synthesis of sedimentary signatures assigned to tidal bore dynamics and impacts. According to the few studies published until now on tidal bore-induced facies within inner estuarine tidal channel infilling successions, only two major signatures can be reported: (1) soft sediment deformations (SSDs) due to ...

Characterisation of unsteady turbulence in breaking tidal bores including the effects of bed roughness [PDF]
, 2010 A tidal bore is an unsteady flow motion generated by the rapid water level rise at the river mouth during the early flood tide. With time, the leading edge of the tidal wave becomes steeper and steeper until it forms a wall of water that is the tidal ...

Journal of Quaternary Science, EarlyView.Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Environmental, ecological and cultural impacts of tidal bores, benaks, bonos and burros [PDF]
, 2009 A tidal bore is a series of waves propagating upstream as the tidal flow turns to rising. It forms during the spring tide conditions when the tidal range exceeds 4 to 6 m and the flood tide is confined to a narrow funnelled estuary with low freshwater ...

How I Do It: Middle Fossa Approach of Facial Nerve Decompression
The Laryngoscope, EarlyView.We present a reproducible, stepwise middle fossa approach for facial nerve decompression focused on the labyrinthine segment, geniculate ganglion, and meatal foramen, with consistent anatomical landmarks to preserve hearing. The article and video detail patient setup, safe corridor creation, and retrograde drilling with practical tips to avoid cochlear

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance
Limnology and Oceanography: Methods, EarlyView.Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...

Mixing and dispersion role of tidal bores [PDF]
, 2004 When a river mouth has a flat converging shape and when the tidal range exceeds 6 to 9 m, the river may experience a tidal bore. A tidal bore is basically a positive surge propagating upstream as the tidal flow turns to rising. The occurrence of a bore has a significant impact on estuarine systems.
