Increased Utilization of Storm Surge Barriers: A Research Agenda …
WEBMar 27, 2023 · The fixed infrastructure of a storm surge barrier system when gates are open typically causes several long-term physical effects. These include locally enhanced water velocities around the open gates (Figure 2; Ralston, 2022), and reductions in velocities and tide amplitudes inside an estuary.
The impact of storm surge barriers on estuaries and ecosystems
WEBAug 22, 2023 · Surge barriers can be an efficient approach to minimize flooding, property damage and loss of life. Yet because of interfering with the flow of water in and out of an estuary, these barriers can cause major changes to saltwater intrusion, affect sediment flows and negatively impact water quality.
Wave and storm surge evolutions in the Pearl River Estuary with …
WEBApr 1, 2023 · The wave and storm characteristics, and their responses to 1990–2020 land reclamations in the Pearl River Estuary (PRE) were investigated by a storm surge model. Besides, the impacts of increasing typhoon intensity (TI) on the changes of waves and storm surges caused by reclamations were also illustrated under the background of …

WEBJul 28, 2021 · This study explored the effects of interactions between waves and current on storm surge in the Pearl River Estuary (PRE) using a fully coupled wave–current model. The model was validated based on in situ observations …
WEB17 Gated storm surge barriers have been constructed or proposed in many estuaries worldwide for 18 coastal flood risk reduction. Past studies have shown that, even when open, a barrier system’s 19 fixed infrastructure can increase estuary stratification and salt intrusion, potentially affecting 20 water quality and ecological processes ...
WEBOur results show that storm surge generally gets larger when channels are dredged and deepened; the largest amplification is observed for fast-moving storms with a short time scale, within estuaries that are highly frictional.
Increased utilization of storm surge barriers: A research agenda …
WEBMar 27, 2023 · Rising coastal flood risk and recent disasters are driving interest in the construction of gated storm surge barriers worldwide, with current studies recommending barriers for at least 11 estuaries in the United States alone.
Sensitivity of Estuaries to Compound Flooding
WEBOct 13, 2021 · The Effect of Increased Storm Surge. An increase in surge height was shown to be a key driver of increased flood depths, compared with an increase in fluvial discharge—for both estuary types (runs H13, H14, D13 and D14 in Table 3). A similar result was shown by Maskell et al. for an idealised estuary.
Changes in Estuarine Sediment Dynamics with a Storm Surge Barrier
WEBFeb 8, 2023 · This modeling study of a storm surge barrier near the mouth of the Hudson River estuary examines potential impacts of the alterations to flow on sediment dynamics in the system. Within about a tidal excursion of the barrier, increased bottom stresses result in erosion and coarsening of the bed.
