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.

Optimising the Detection of Southern Toadlets (Pseudophryne semimarmorata): A Comparative Study of eDNA and Conventional Survey Methods

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT Accurate and reliable monitoring of amphibians is essential for informing their conservation. Pseudophryne semimarmorata (southern toadlet) is a species of endangered brood frog with a largely terrestrial life history that has experienced widespread decline across southern Australia.

Human Stem Cell Transplantation, Immunosuppression, and Noninvasive In vivo Cell Tracking in the Mouse Brain

Current Protocols, Volume 6, Issue 8, August 2026.
Abstract Stem cell therapies have emerged as potential therapeutics of interest for many central nervous system diseases, including stroke, epilepsy, neurodegenerative diseases, and traumatic brain injury. Preclinical models are required to evaluate the migration of transplanted stem cells to various areas of the brain, monitor graft survival to ...

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Stayin' alive: Strategies to reduce predation on target species are context dependent

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Restoration and conservation efforts often aim to reduce predation, particularly by reducing interactions with nonnative predators in heavily disturbed and invaded ecosystems. For Chinook salmon Oncorhynchus tshawytscha, a highly valued but declining fishery, potentially useful freshwater rearing habitat restoration strategies may include ...

Flume experiments on macro‐roughness elements: Hydraulic response and potential influences on flood risk and habitat diversity

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Physical modelling of macro‐roughness elements for river restoration showed that backwater rise depends mostly on the relative structure width and approaching flow Froude number, with only minor differences among designs. Internal geometry modulated turbulent kinetic energy and flow partition between gap and wake.

How many tagged stones are needed to estimate the mean travel distance of sediment from tracer experiments in gravel‐bed rivers?

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
We propose a statistical model to analyse the impact of tracer sample size and tracer loss on the representativeness of samples in tracer studies in gravel‐bed rivers. Abstract Tagged particles (painted, with inserted magnets, RFID labelled) used as tracers have often been deployed in field experiments focused on tracking the displacement of river ...
