Freshwater Pearl Mussel (Margaritifera Margaritifera) Host Choice and Behavioural Responses to Changes in Flow Regime [PDF]

, 2016
The endangered freshwater pearl mussel (Margaritifera margaritifera), one of the longest-lived invertebrates, are threatened globally. Scotland, UK, remains a stronghold, however even here the population is declining due to factors such as habitat ...

Theoretical and experimental evidence of non-symmetric doubly localized rogue waves

, 2014
We present determinant expressions for vector rogue wave solutions of the Manakov system, a two-component coupled nonlinear Schr\"odinger equation. As special case, we generate a family of exact and non-symmetric rogue wave solutions of the nonlinear ...

Estimating Discharge From Undular Hydraulic Jumps: Feasibility Assessment Based on Flume Experiments

Water Resources Research
Rapids are common in steep rivers, often forming where flow transitions from supercritical (Froude number, Fr > 1) to subcritical (Fr

Densely distributed and real-time scour hole monitoring using piezoelectric rod sensors [PDF]

, 2019
This study aims to validate a piezoelectric driven-rod scour monitoring system that can sense changes in scour depth along the entire rod at its instrumented location.

Longitudinal Dispersion and Hyporheic Exchange of Neutrally Buoyant Microplastics in the Presence of Waves and Currents

Microplastics
An experimental study was conducted to identify the behaviour of neutrally buoyant microplastics (specific density, 0.94) in different hydrodynamic conditions while focusing on combined wave–current conditions and the mixing across the hyporheic zone ...

Effects of Benthic Burrows on Hyporheic Exchange

Water Resources Research
Macrobenthic invertebrates are widely distributed on sediments, and the micro‐morphology such as burrows and sand mounds due to their bioturbation activities can cause substantial changes in hyporheic exchange (HE).

Groundwater sapping channels: Summary of effects of experiments with varied stratigraphy [PDF]

Experiments in the recirculating flume sapping box have modeled valley formation by groundwater sapping processes in a number of settings. The effects of the following parameters on sapping channel morphology were examined: surface slope; stratigraphic ...

Look At That Bump [PDF]

In this activity, students focus on the physical and chemical processes associated with the Charleston Bump, a series of rocky scarps, mounds, overhangs, and flat pavements that rise from more than 700 m at the surface of the Blake Plateau to within 400 ...

Experimental and Numerical Investigation on the Impact of Emergent Vegetation on the Hyporheic Exchange

Water Resources Research
Hyporheic exchange leads to the transfer of gases, solutes, and fine particles across the sediment‐water interface, playing a critical role in biogeochemical cycles and pollutant transport in aquatic environments.
