El Museo del Puerto Fluvial de Caesaraugusta [PDF]

Boletín del Museo Arqueológico Nacional, 2017
El Museo de sitio, gestionado por el Ayuntamiento de Zaragoza, fue inaugurado en el año 2000. Alberga un conjunto monumental, fechado entre finales del siglo I a. C. y el siglo I d. C., que daba continuidad al trazado de los pórticos del foro, perfilando

Facies and the Architecture of Estuarine Tidal Bar in the Lower Cretaceous Mcmurray Formation, Central Athabasca Oil Sands, Alberta, Canada

Energies, 2019
In this study, data obtained from the Lower Cretaceous McMurray Formation in the central Athabasca Oil Sands, northeastern Alberta, Canada, are examined and used to establish the architecture of stacked fluvial and estuarine tidal bar deposits.

Paleohydrology and Machine-Assisted Estimation of Paleogeomorphology of Fluvial Channels of the Lower Middle Pennsylvanian Allegheny Formation, Birch River, WV

Frontiers in Earth Science, 2020
Rivers transport sediments in a source to sink system while responding to allogenic controls of the depositional system. Stacked fluvial sandstones of the Middle Pennsylvanian (Desmoinesian Stage, ∼310–306 Ma) Allegheny Formation (MPAF) exposed at Birch ...

Hydrodynamic Modelling of Wave Overtopping over a Block-Covered Flood Defence

Journal of Marine Science and Engineering, 2022
Wave overtopping can cause erosion on the landward slope due to high flow velocities and turbulence that cause high stresses on the cover. Innovative block revetments such as Grassblocks protect the subsoil of the dike against erosion.

Past hydrological extreme events in a changing climate [PDF]

, 2015
Fluvial records contain evidence of past hydrological changes in terms of water/sediment fluxes and extreme hydrological events (floods), which can be linked to Earth's climate variability.

Depth Estimation of Submerged Aquatic Vegetation in Clear Water Streams Using Low-Altitude Optical Remote Sensing

Sensors, 2015
UAVs and other low-altitude remote sensing platforms are proving very useful tools for remote sensing of river systems. Currently consumer grade cameras are still the most commonly used sensors for this purpose.

Fluvial instabilities

The Physics of Fluids, 2020
Fluvial instabilities originate from an interplay between the carrier fluid and the erodible loose boundary at their interface, manifesting a variety of sedimentary architectures with length scales spanning from a few millimeters to hundreds of meters ...

Does deposition depth control the OSL bleaching of fluvial sediment?

, 2014
The Optically Stimulated Luminescence (OSL) signal from fluvial sediment often contains a remnant from the previous deposition cycle, leading to a partially bleached equivalent-dose distribution.

Quantifying Below-Water Fluvial Geomorphic Change: The Implications of Refraction Correction, Water Surface Elevations, and Spatially Variable Error

Remote Sensing, 2019
Much of the geomorphic work of rivers occurs underwater. As a result, high resolutionquantification of geomorphic change in these submerged areas is important.

Evaluation of Morphodynamic Controls on the Preservation of Fluvial Meander‐Belt Deposits

Geophysical Research Letters, 2021
The way river morphodynamics influence the preservation of point‐bar deposits at multiple scales is not fully understood. Employing time‐lapse trajectories of natural rivers, a numerical model is used here to simulate planform evolutions of meander‐belt ...
