Granular Flow Experiments for Validation of Numerical Flow Models

25 Jun 2016 | Contributor(s): Amy Webb, Marcus I Bursik

Many types of geophysical flows such as debris avalanches and pyroclastic flows pose significant danger to both people and property. Understanding granular avalanche behavior and particle interaction during the course of a flow is very important in the development of granular flow models. Since...

Maar-diatremes - a course module

13 Jun 2016 | Contributor(s): Greg A Valentine, Alison Graettinger

Maar-diatremes are one of the most common volcanic landforms on Earth, and represent an end-member type of volcano whose eruptions are dominated by explosive, subsurface magma-water interaction.  Thus they should form an important component of volcanology courses.  The recent decade has...
