Produktbeschreibung

Exploring the properties, behavior, and dynamics of particulate gravity currents

Particulate gravity currents involve the movement of mixtures of particles and fluid under the influence of gravity. Examples in the natural environment include snow avalanches, pyroclastic flows, and seafloor turbidity currents. Understanding how particles move, mix, stratify, and settle has applications such as hazard mitigation and pollution management.

Particulate Gravity Currents: Theory, Experiments, and Environmental Applications presents experimental, numerical, and field studies of particulate gravity currents, offering new insights into their properties, behavior, and dynamics.

Volume highlights include:

• Explorations of cohesive and non-cohesive sediment and transport
• Applications of theoretical understanding to real-world subaerial and subaqueous processes
• Studies using the latest techniques, including 3D numerical simulation
• Broader relevance beyond the natural environment to other types of particulate and non-particulate gravity currents
