Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges
River Research and Applications, EarlyView.ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

River Research and Applications, EarlyView.ABSTRACT Invasive species such as grass carp (Ctenopharyngodon idella) pose substantial ecological threats to North American freshwater ecosystems. Understanding their early life stage behavior is critical for management efforts. From spawning to hatching, invasive carp eggs must remain suspended in the water column while drifting downstream for the ...

Science Education, EarlyView.ABSTRACT Students' diverse levels of knowledge and competence—shaped by individual interests and educational debts, including structural, systemic, and institutional barriers—create substantial cognitive heterogeneity in instructional settings. Adequately addressing this heterogeneity is challenging.

The behaviour of fluids can be described by the well-known mathematical model known as the Navier-Stokes equations. The original equations include formulations for the conservation of momentum, energy and mass, therefore leading to three momentum equations, one energy equation and one continuity equation. The form presented below is a simplification of

At high Reynolds number the fluid velocity is exponentially sensitive to perturbations of the problem data. This sensitivity, however, is not uniform. The large structures (large eddies) evolve deterministically and are thus not sensitive [BFG02]. The small eddies are sensitive because they have a random character.
