Special Issue Information

Dear Colleagues,

Understanding the dynamics of water flow and its interactions with sediments, soils, and engineered structures is fundamental to sustainable water resource management, environmental protection, and the resilience of hydraulic infrastructure. Recent advances in field observation, laboratory testing, and numerical modeling have greatly enhanced our ability to describe, predict, and manage these complex processes. Yet, many challenges remain in linking physical mechanisms with practical engineering and environmental applications.

The goal of this Special Issue, “Fluid Dynamics and Hydrological Processes”, is to present innovative studies and multidisciplinary approaches that advance our understanding of fluid motion, sediment transport, bed evolution, and pollutant migration in both natural and engineered systems. This topic lies at the core of Geosciences, bridging fundamental hydrodynamics with applied environmental and civil engineering research.

This Special Issue welcomes contributions on, but not limited to, the following themes:

  • Flow structure, turbulence, and velocity field characterization in open channels and coastal zones;
  • Sediment transport, erosion, deposition, and bed deformation processes;
  • Scour and local bed response around hydraulic and coastal structures such as bridges, pipelines, levees, and breakwaters;
  • Water and soil contamination, pollutant transport mechanisms, and their coupling with hydrological processes;
  • Advanced monitoring, remote sensing, and data-driven methods for flow, sediment, and environmental assessment.

We invite original research articles, reviews, and technical notes that provide new insights into hydrodynamics, morphodynamics, and hydro-environmental interactions, supporting the development of sustainable and resilient water and environmental management strategies.

A wave-resource characterization along the coast of Vietnam was performed based on the 12-year period from 2007 to 2018, using the structured-grid Simulating WAves Nearshore (SWAN) model with a ~2.3 km spatial resolution. Extensive model validations were performed using an observed nearshore dataset and ERA5 offshore datasets. The wave parameters, significant wave height, wave period, total wave energy and omnidirectional wave power varied both spatially and temporally, with a strong seasonal pattern influenced by the northeast and southwest monsoons, with the impact of the northeast monsoon being stronger. Wave energy resources were highest in winter and lowest in summer, making the southcentral coast of Vietnam a prime location for wave energy harvesting. However, further feasibility and design studies are needed before wave farms can be established. The Gulf of Tonkin and the Gulf of Thailand had lower wave energy due to wind distribution, shadowing effects and changes in water depth. This study also noted the impact of ENSO phases on wave conditions. Year-round, El Niño generally weakened winds, leading to smaller waves and reduced wave energy, while La Niña had the opposite effect. Additionally, tropical cyclones can further amplify significant wave height, especially during both ENSO phases in July, thereby increasing wave energy. Full article
