Jet Scour in Cohesive and Non-Cohesive Soil
, 2022 A safe design of hydraulic structures depends on reliable estimations of the scour generated by the interaction between flow, structure, and bed sediments. Non-cohesive and cohesive soils are characterized by very different scour processes. Consequently, the behavior of the two soil types under scour has usually been studied separately.

Construction and testing of self-drilled soil nails [PDF]
, 2016 Current standards and best practice guidance recognise that testing of self-drilled hollow bar soil nails can be problematic as conventional packers and debonded lengths cannot be constructed.

Modelling the brightness increase signature due to asteroid collisions
, 2015 We have developed a model to predict the post-collision brightness increase of sub-catastrophic collisions between asteroids and to evaluate the likelihood of a survey detecting these events.
