Partial Entrance Restriction as a Potential Tidal Flood Mitigation Strategy in a Large Urban Estuary

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Tidal flooding in estuaries is expected to worsen as sea‐level rise (SLR) continues to accelerate and increases storm surge height. Conventional structural defences are often unsustainable, while nature‐based solutions like managed realignment require extensive land to be repurposed.

Marine Habitat Mapping Incorporating Both Derivatives of LiDAR Data and Hydrodynamic Conditions

Journal of Marine Science and Engineering, 2015
Accurate and efficient species-based marine habitat assessment is in great demand for the marine environment. Remote sensing techniques including airborne light detection and ranging (LiDAR) derived bathymetry can now be used, in concert with suitable ...

A First Look at the Snow/Ice Penetration Effect of SWOT Observations on Water Level of Global Glacial Lakes

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission promises quasi‐global monitoring of glacial lakes, yet the elevation difference arising from its Ka‐band radar penetrating lake snow/ice cover remains unquantified. This poses a challenge to assessing their level changes.

Long-term Satellite-derived Bathymetry of Arctic Supraglacial Lake from ICESat-2 and Sentinel-2 [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The polar ice sheets serve as natural thermostats, regulating Earth’s temperatures. The Greenland Ice Sheet (GrIS), the second-largest ice sheet, is a critical indicator of climate change and global warming.

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Reshaping of San Jose Island, TX, USA, by Unconfined Washover and Channelized Washout During Hurricane Harvey

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
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,

Spaceborne active-passive optical fusion bathymetry in coastal waters: the implications of ICESat-2 photons

International Journal of Digital Earth
Up-to-date bathymetric data is essential for global coastal management and protection. Conventional surveying equipment is not only inefficient but also difficult to reach on remote island coasts.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream

Water Resources Research, Volume 62, Issue 5, May 2026.
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 ...

Forecasting of Volcanic–Flow Tsunamis Through Integrated Data From Laboratory Experiments and the 2019–2021 Stromboli Events, Italy

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Stromboli, Italy, is a unique volcano worldwide with near‐continuous eruptions monitored by a multi‐sensor network. Between 2019 and 2021, three events produced pyroclastic density currents along the Sciara del Fuoco that entered the sea and generated tsunamis, providing a unique data set linking flow dynamics to tsunami generation near the ...

Water level and volume estimations of the Albano and Nemi lakes (central Italy)

Annals of Geophysics, 2008
In April 2006 an airborne laser scanning (LIDAR) survey of the Albano and Nemi craters was carried out to obtain a high resolution digital terrain model (DTM) of the area.
