Sampling Strategies to Improve Passive Optical Remote Sensing of River Bathymetry

Remote Sensing, 2018
Passive optical remote sensing of river bathymetry involves establishing a relation between depth and reflectance that can be applied throughout an image to produce a depth map. Building upon the Optimal Band Ratio Analysis (OBRA) framework, we introduce

Comparisons between sediment transport models and observations made in wave and current flows above plane beds [PDF]

, 1997
As a part of the MAST2 G8-M Coastal Morphodynamics project, the predictions of four sediment transport models have been compared with detailed laboratory data sets obtained in the bottom boundary layer beneath regular waves, asymmetrical waves, and ...

Grain-size characteristics and net transport patterns of surficial sediments in the Zhejiang nearshore area, East China Sea

Oceanologia, 2020
Summary: Spatial variations in grain-size parameters can reflect sediment transport patterns and depositional dynamic environments. Therefore, 616 surficial sediment samples taken from the Zhejiang nearshore area in the East China Sea were analyzed to ...

A model for fluvial bedrock incision by impacting suspended and bed load sediment [PDF]

, 2008
A mechanistic model is derived for the rate of fluvial erosion into bedrock by abrasion from uniform size particles that impact the bed during transport in both bed and suspended load.

Paleogeographic numerical modeling of marginal seas for the Holocene – an exemplary study of the Baltic Sea [PDF]

Earth System Dynamics
The sustainable management of marginal seas is based on a thorough understanding of their evolutionary trends in the past. The paleogeographic evolution of marginal seas is controlled not only by global and regional driving forces (eustatic sea-level ...

Wave simulation for the design of an innovative quay wall: the case of Vlorë Harbour [PDF]

Natural Hazards and Earth System Sciences, 2017
Sea states and environmental conditions are basic data for the design of marine structures. Hindcasted wave data have been applied here with the aim of identifying the proper design conditions for an innovative quay wall concept.

Sediment transport trend and its influencing factors in coastal bedrock island sea areas-a case study of Chudao island, China

Frontiers in Marine Science, 2023
Coastal bedrock islands sea areas have a unique natural environment, frequent human activities, and complex sedimentary dynamic processes. In this paper, we select the Chudao Island sea area off the coast of Shandong Peninsula, China, as a typical ...

Effects of temperature on in vitro sediment reworking processes by a gallery biodiffusor, the polychaete Neanthes virens [PDF]

, 2004
Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern ...

Numerical Simulation of Slope–Gully–Stream Sediment Transport Process with Water and Gravity Erosion

Frontiers in Earth Science, 2022
Soil erosion has become a global problem with serious consequences. It is the source of sediment in rivers, and the subsequent sediment transport is important.
