Underwater Photogrammetry Application for Coral Reef Mapping and Monitoring

International Journal on Advanced Science, Engineering and Information Technology, 2020
Underwater 3D reconstruction techniques such as underwater photogrammetry are the latest trend in low cost survey techniques. This article explains how the data acquisition process is up to the process of producing an underwater photo map.  Automatic data processing for coral reef objects from the initial data acquisition stage to building 3D models ...

Underwater 3D Scanning System for Cultural Heritage Documentation

Remote Sensing, 2023
Three-dimensional capturing of underwater archeological sites or sunken shipwrecks can support important documentation purposes. In this study, a novel 3D scanning system based on structured illumination is introduced, which supports cultural heritage ...

Quantifying Decadal‐Scale Impacts of Flow and Sediment Regulation on an Alpine Gravel‐Bed River and Consequences for Fish Habitat: The Buëch River, France

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Predicting long‐term effects of dam operation and restoration strategies on channel morphology remains a complex but essential challenge for maintaining fish habitat through effective reservoir management. We address this challenge by integrating a one‐dimensional morphodynamic model and a generalized fish habitat model using one‐dimensional ...

UNDERWATER PHOTOGRAMMETRY METHODS FOR A PECULIAR CASE-STUDY: SAN DOMENICO (PRATO-ITALY) [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Abstract. San Domenico Church (Prato, Tuscan, Italy) is a very peculiar case of terrestrial archaeology surveyed with underwater archaeological photogrammetric approach. The vault of the choir was completely filled by a very important numbers of potteries, which is very interesting building technique.

Refinement of a Framework for Moving Aircraft River Velocimetry (MARV) and Application to Particle Tracking Along Alaskan Rivers

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

Linking Remotely Sensed Hydromorphological Conditions With Biological Observations to Estimate Salmon Spawning Capacity

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Performing ecohydraulic assessments of salmon habitat is essential for planning and evaluating management actions. Current in situ and modelling approaches, although accurate, can be time‐consuming and expensive, which limits the areal extent of the study.

MONITORING CORAL GROWTH – THE DICHOTOMY BETWEEN UNDERWATER PHOTOGRAMMETRY AND GEODETIC CONTROL NETWORK [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Abstract. Creating 3-dimensional (3D) models of underwater scenes has become a common approach for monitoring coral reef changes and its structural complexity. Also in underwater archeology, 3D models are often created using underwater optical imagery.
