... Previously, abrupt changes in bedding, grading and pumice concentration have been used to distinguish deposits of discrete pyroclastic currents, or ‘flow-units’ (e.g. Sparks et al., 1973). More recently it has ... See full document

... Particle-laden density currents deposit and/or erode the surface over which they travel. This means that the suspended mass changes with time, i.e. they are non- conservative. They have the potential to ... See full document

... Conditional on whether or not we want to solve for squirmer surface tractions, we may not necessarily choose the double layer representation for the squirmer. There is no straightforward way to develop a second-kind ... See full document
