Prediction of Maximum Scour Depth Using Scaled Down Bridge Model in a Laboratory

, 2019
Recently, United States faced catastrophic flooding in West Virginia, Texas, Louisiana, Oklahoma, Arkansas, and the flooding resulted in several bridge failures. Among them, bridge scour is one of the main causes behind many bridge failures and financial losses as well as loss of life.

Task‐Evoked Functional Activation and Coupling With CSF Flow Detected in the Human Brain With Ultrashort Echo Time fMRI at 7 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Ultrashort and zero echo time (UTE and ZTE) MRI techniques generate functional contrast through inflow effects, making them suitable for studying cerebral blood flow and cerebrospinal fluid (CSF) dynamics. In a 7‐T study of 13 participants performing a visual task, we demonstrate that UTE produced robust, reproducible activations with group‐level ...

Enabling effective urban green space stewardship through planning: A qualitative comparative analysis in Southwest England

People and Nature, Volume 8, Issue 8, Page 2559-2575, August 2026.
Abstract Amid increasing urbanisation and biodiversity decline, ‘effective stewardship’ of urban green space (UGS) is a complex but critical nature‐based solution for long‐term environmental, social and economic gain. Combining stewardship and sense‐of‐place frameworks with European nature‐based solutions guidance, we investigate which social and ...

Spatial Heterogeneity and Nonlinear Influencing Mechanisms of Vegetation Carbon Sequestration Capacity in the Southwest China Karst Region

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Understanding of the spatiotemporal dynamics of vegetation carbon sequestration capacity (VCSC) in Southwest China's contiguous karst region is critical for regional carbon cycling. Using MOD17A3 data from 2001 to 2023, we analyzed spatial heterogeneity in vegetation net primary productivity (NPP) and applied Geodetector to evaluate nonlinear ...

Redistribution of Sediment and Particulate Mercury Within Upstream Reaches of Galveston Bay in Response to Hurricane Harvey

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Extreme storms and flooding can remobilize legacy contaminants stored in the sediment bed; however, event‐scale models that resolve the transport of these materials remain underdeveloped. This study developed a numerical model of contaminated sediment transport during Hurricane Harvey (August 2017), which struck the upstream reaches of ...

Flood‐Scale Bedload Transport Dynamics From Acoustic Monitoring Compared With 2D Hydro‐Sedimentary Modeling

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Accurate estimation of bedload fluxes is critical to understanding sediment transport processes and associated channel evolution in gravel‐bed rivers, however, traditional direct measurements using samplers are time‐consuming and complex. To overcome these limitations, new indirect methods have been developed to estimate fluxes from bedload ...

A Robust, Low‐Cost Conductance Sensor for High Resolution Real‐Time Monitoring of Streambed Pore Water Dynamics

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The groundwater—surface‐water interface is an important regulator of many biogeochemical processes along river corridors. One of the main drivers of these processes is the pore water travel time along hyporheic flow paths. However, our understanding and ability to predict the spatial‐temporal dynamics of subsurface travel times are limited ...
