Special Issue Information

Dear Colleagues,

Coastal regions face evolving challenges due to natural processes and human activities. The interaction of waves, currents, tides, and coastal structures requires a solid understanding of hydrodynamic processes to design effective protection strategies and promote sustainable coastal management.

This Special Issue, “Coastal Hydrodynamics, Conservation and Restoration: Numerical Investigation, Experimental Research and Technical Application,” aims at collecting high-quality contributions that advance knowledge and practice in Coastal Hydrodynamics. Combining different approaches, from computational modeling and laboratory experiments to field applications, this collection seeks to provide a comprehensive overview of recent advancements.

The goal of this Special Issue is to encourage a deeper understanding of coastal processes and promote the development of innovative, resilient and sustainable solutions for the protection of coastal environments and communities worldwide, offering new insights, methodologies, and case studies that can support effective coastal engineering practices.

We welcome studies presenting new methodologies, insights, and case studies that can inform effective coastal engineering practices (e.g., numerical simulations addressing nearshore hydrodynamics and coastal processes; experimental research validating theoretical models and informing engineering design; technical applications that transfer research outcomes into practical solutions).

Dam-break flows over erodible beds represent a complex fluid–solid interaction problem characterized by extreme turbulence and rapid morphological changes. This study investigates the dynamics of such flows over inclined granular beds by integrating an advanced Moving Particle Semi-implicit (MPS) method. To accurately resolve the transition between static and kinetic granular regimes, I introduce a state-dependent tangential friction model that explicitly distinguishes between sticking and sliding conditions based on local force balance. Furthermore, the momentum exchange between the fluid and solid phases is rigorously modeled using the porosity-dependent drag formulation. The numerical results demonstrate a distinct regime shift in energy dissipation: while low-inclination beds (0–4%) promote distributed sediment transport, steep-inclination beds (8–12%) trigger a localized “Shielding Effect”. In this regime, the surge’s horizontal kinetic energy is rapidly converted into vertical potential energy and frictional work, forming a deep sacrificial scour hole that acts as a topographical energy sink. This mechanism effectively mitigates the destructive potential of the surge in downstream areas. The proposed method provides a robust tool for predicting morphological feedback and designing topographical countermeasures for disaster mitigation in hydraulic and coastal environments.
