Waves and vortices in the inverse cascade regime of stratified turbulence with or without rotation

, 2015
We study the partition of energy between waves and vortices in stratified turbulence, with or without rotation, for a variety of parameters, focusing on the behavior of the waves and vortices in the inverse cascade of energy towards the large scales.

How Managed Realignment Modifies Salt Intrusion in Short Estuaries

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract The global loss of intertidal habitats undermines ecosystem services. To restore ecological value and enhance flood protection, managed realignment sites (MRSs) are increasingly implemented along estuaries worldwide. At the same time, estuarine salt intrusion intensifies due to climate change and anthropogenic impacts.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...

Effects of the Application of a Stern Foil on Ship Resistance: A Case Study of an Orela Crew Boat

International Journal of Technology, 2017
The effects of the application of a stern hydrofoil on ship resistance were studied numerically using computational fluid dynamics (CFD) and were verified using data from model tests. A 40 m planing-hull Orela crew boat, with target top speed of 28 knots

A Numerical Study of the Effects of Density Contrast on Flow, Turbulence, and Mixing at the Negro/Solimoes Confluence, Brazil

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

Flow Processes in a Diffluence‐Confluence Unit on a Large‐Shallow River Under Different Discharges

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Understanding the hydrodynamics of bifurcation and confluence zones is essential for effective river management. This study investigated the complex flow structure in a large diffluence‐confluence unit (width‐depth ratio >100) of the Middle Yangtze River, utilizing systematic field observations of three‐dimensional velocities under low to high
