Observations on water level fluctuations in snow due to rain and snowmelt
(Chapter, 1996)Meteorological parameters, snowpack conditions and water level fluctuations in snowpack due to rain and snowmelt, have been registered during 5 winters at two slushflow sites in Rana, North Norway. A noticeable rise of ... -
Offshore Wind Turbine Foundations State of the Art
(Chapter, 2019)The huge growth and intense development in the European offshore wind power sector over the last decade have created significant achievements within the wind turbine foundation technology. The state of the art focusing on ... -
On avalanche (front) velocity measurements at the Ryggfonn avalanche test site and comparison with observations from other locations
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Besides the runout distance of an avalanche, information on avalanche intensity along the path are often required for hazard zoning or planning of mitigation measures. The avalanche (front) velocity is a common measure as ... -
On avalanche measurements at the Norwegian full-scale test-site Ryggfonn.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)Avalanche measurements and observations, which were carried out at the Ryggfonn test-site, Norway, on 16 April 2005, are analyzed. The data include pulsed Doppler radar measurements, impact pressure readings from load cells ... -
On avalanche run-up heights on deflecting dams: Centre of mass computations compared to observations.
(NGI Publication;203, Chapter, 1998)This article reports on the observed run-up heights of avalanches in terrain formations that act as "natural deflecting dams" with oblique angle of incidence. To compensate for the deficiencies of today's methods, the ... -
On snow avalanche flow regimes: Inferences from observations and measurements.
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)Mixed dry-snow avalanches are commonly thought to consist of a dense core and a dilute suspension layer, even though observations and measurements from Canada and Russia have long indicated the presence of an intermediate-density ... -
Operational use of a snowpack model for the avalanche warning service in Switzerland : model development and first experiences
(NGI Publication;203, Chapter, 1998)The national Swiss avalanche warning service must provide high quality avalanche danger forecasts with an increasing spatial resolution. For this purpose, forecasters require objective tools to judge local and regional ... -
Opportunity of detailing avalanche forecasts
(NGI Publication;203, Chapter, 1998)The national Swiss avalanche warning service must provide high quality avalanche danger forecasts with an increasing spatial resolution. For this purpose, forecasters require objective tools to judge local and regional ... -
An overview of avalanche forecasting models and methods
(NGI Publication;203, Chapter, 1998)This overview resumes first the historical development of avalanche forecasting in different countries of the world. It yields the most basic definitions like "avalanche danger" and presents the major problems of avalanche ... -
An overview of natural hazard zoning with special reference to avalanches
(NGI Publication;203, Chapter, 1998)Natural hazards are increasingly a limiting factor in mountainous countries in connection with the growing population and economical development. People become more and more estranged to environmental conditions and are ... -

PANDALP : a new penetrometer for snow investigation
(NGI Publication;203, Chapter, 1998)This paper presents a new tool for snow investigation, issued from a portable dynamic penetrometer Panda with variable energy for soil investigation. After a brief presentation of this apparatus, a comparable study between ... -
Perception of risk in avalanche terrain
(The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2012)Although avalanche training and the risk minimization strategies have greatly evolved and are being widely taught to recreational and professional users, too many serious accidents continue to happen within the educated ... -
Piezoprobe test interpretation on soft clay
(Chapter, 2017)This paper describes and compares different methods to interpret dissipation tests on soft clays by using piezoprobe tests. Emphasis is given to estimate initial pore-water pressure (ui), in situ equilibrium pore-water ... -
Plenary: Progress of living with landslide risk in Europe
(Chapter, 2014)The need to protect people and property with a changing pattern of landslide hazard and risk caused by climate change and changes in demography, and the reality for societies in Europe to live with the risk associated with ... -
Pore pressure reduction and settlements induced by deep supported excavations in soft clay
(Chapter, 2016)As a part of the large research project, "LimitingDamage" (BegrensSkade), common causes of damage or unexpectedly large settlements connected to ground and foundations works have been investigated. It can be seen that ... -
The potential of sedimentology and stratigraphy in avalanche-hazard research
(NGI Publication;203, Chapter, 1998)Detailed sedimentology studies in cross sections and studies of recent processes on avalanche-dominated colluvial fans have been combined in order to evaluate the characteristic sedimentary facies of avalanche processes. ...
