Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Measuring avalanches to manage risk
| Description | The new radar has a better performance than the old version. In particular, we can resolve the lateral movement of the avalanche more effectively. Hence, the developmental aspects have been achieved. We have also been working on data processing algorithms and analysing the data obtained to elucidate the flow physics to a greater extent. |
| Exploitation Route | When we have synthesised the data, we will be able to provide information on the avalanche flow physics that can be used for engineering modelling developmental work. This will then feed into applied work such as risk zoning in Alpine terrain. We are exploring extending the radar's domain of application to pyroclastic flows in volcanic regions. |

| Description | Our findings from this project have resulted in new radar designs for the measurement of geophysical mass movement flows. Citations to our work indicate that there will be societal impacts as a consequence in the medium term (better avalanche models;better risk analysis for alpine areas). |

| Title | Gradual Wavelet Reconstruction |
| Description | This method permits controlled randomisation of time series for studying their nonlinear characteristics, or for modelling data by including given nonlinear characteristics. It is wavelet-based and extends previous Fourier-based methods. |
| Type Of Material | Data analysis technique |
| Year Produced | 2010 |
| Provided To Others? | Yes |
| Impact | There have now been applications of this method in hydrology and fluid mechanics, with more being developed in neuroscience. It is supporting the analysis of the data in the funded research projects (e.g. analysing avalanche radar data). |
| Description | PhD collaboration on avalanche dynamics and signal processing |
| Organisation | National Research Institute of Science and Technology for Environment and Agriculture |
| Country | France |
| Sector | Public |
| PI Contribution | Supervising the second half of the PhD and providing expertise on wavelet data processing. |
| Collaborator Contribution | Provided funds to support the first half of the PhD via a EU research project. |
| Impact | We have a paper in review and the PhD thesis is about to be submitted. |
| Start Year | 2014 |
| Description | SLF collaboration |
| Organisation | Swiss Federal Institute for Forest, Snow and Landscape Research |
| Department | WSL Institute for Snow and Avalanche Research SLF |
| Country | Switzerland |
| Sector | Academic/University |
| PI Contribution | We have developed and tested the radar for measuring snow avalanche dynamics. We have travelled to the site to make measurements. |
| Collaborator Contribution | Swiss colleagues have helped install the instruments on their site (which is difficult to access) and helped install appropriate power and data recording facilities |
| Impact | We have published papers together (reported elsewhere) and developed a stand for the Royal Society Summer Science Exhibition. |
