Characterisation and multiphase flow modelling of a rock avalanche turned into a supraglacial debris flow: Insights from Mt Job, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Photographs before (left) and after (right) the May 2023 landslide in Mt Job, Mount Meager Volcanic Complex, British Columbia, Canada. The initial rock avalanche impacted the glacier, producing a 4.5‐km‐long debris flow that ran over it and down the valley.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Microwave Remote Sensing of Soil Moisture [PDF]

, 1985
Because of the large contrast between the dielectric constant of liquid water and that of dry soil at microwave wavelength, there is a strong dependence of the thermal emission and radar backscatter from the soil on its moisture content.

Past Field Experiments of Solar Radiation Modification: A Review of the Scientific and Technical Aspects for Governance

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract As global warming intensifies, Solar Radiation Modification (SRM) has drawn increasing scientific and policy interest as a potential means to temporarily offset climate impacts. This review examines past SRM (or SRM‐like) field experiments, categorized into three primary techniques: Tropospheric and Stratospheric Aerosol Injection (SAI ...
