Design considerations of suction caisson foundations for offshore wind turbines in Southern China
(Peer reviewed; Journal article, 2020)Suction caisson foundations are increasingly considered as a foundation solution for offshore wind farm development in China. This paper outlines the design considerations for developing a suction caisson supported jacket ... -
Design criteria and location of snow fences
(Journal article, 1985)The paper describes experience gained in Norway regarding the design criteria and use in practice of snow fences . The paper is based on theoretical studies on drifting snow, model experiments and experience accumulated ... -
Design criteria for cylindrical masts exposed to snow creep forces.
(NGI Publication;203, Chapter, 1998)Based on 23 years of measurements of snow creep forces on cylindrical masts, a relation between the pressure and snow parameters as snow depth, density and temperature, has been established. The long observation period has ... -
The design of avalanche protection dams : Recent practical and theoretical developments
(EUR;23339, Research report, 2009)This book discusses the design of dams and other protective measures in the run-out zones of wet- and dry-snow avalanches. It summarises recent theoretical developments and the results of field and laboratory studies, ... -
The design of avalanche protection dams. Recent practical and theoretical developments
(Lecture, 2008)Recent experimental and theoretical studies of the flow of avalanches against obstructions have been used, in combination with traditional design guidelines, to formulate recommendations for the design of dams and other ... -
Design of snow avalanche deflecting dams
(Chapter, 2000)Extensive effort has been put into improved understanding of avalanche deflection over the last two years. This paper discusses construction of deflecting dams in steep terrain, and gives an in-depth description of the ... -
Designing and Performance Evaluation of Biochar Production in a Top-Lit Updraft Upscaled Gasifier
(Journal article, 2015)The Original Belonio Rice Husk Gasifier (OBRHG), initially of height of 0.6 m, diameter of 0.15 m and thickness of 0.025 m was tested for biochar production through air gasification of rice husk (RH) and the design was ... -

Determinación de la velocidad de avalanchas de nieve mediante datos sísmicos
(Chapter, 2006)Seismic instrumentation has proved to be a reliable tool for snow avalanche detection. In this approach, besides the detection skills of our system we pretend to go one step further. We aim to infer a physical parameter ... -
Determination of cyclic soil parameters for offshore foundation design from an existing data base
(Peer reviewed; Journal article, 2022) -
Developing a relationship between static Young’s modulus and seismic parameters
(Journal article, 2022-07-19)Mechanical properties of petroleum reservoirs can be determined via static techniques based on laboratory triaxial tests under reservoir conditions. Dynamic approaches represent an alternative in cases where such static ... -
Development of an enhanced CPT system for Dogger Bank
(Chapter, 2022)An enhanced seafloor CPT system has been developed to support completion of the soil investigation campaign for Dogger Bank. This enhanced system has a demonstrable and significant performance increase over standard seafloor ... -

Differentiating reefal ridges from relict coastal ridges: Lessons from the seismic geomorphologic study of buried Miocene buildups (North West Shelf, Australia)
(Peer reviewed; Journal article, 2023)Linear buildups formed in tropical carbonate environments are often interpreted as bioconstructed reefs. Nevertheless, coastal processes can also form extensive sedimentary ridges exhibiting buildup morphologies. This study ... -
The differentiation of thaws in connection with slushflow occurrences.
(NGI Publication;203, Chapter, 1998)Classification of meteorological conditions accompanying slushflow occurrences is attempted. Days with mean daily air temperature above O°C have been chosen for the analysis. Each day has been described with a set of ... -
Digital Drill Core Models: Structure-from-Motion as a Tool for the Characterisation, Orientation, and Digital Archiving of Drill Core Samples
(Peer reviewed; Journal article, 2020)Structure-from-motion (SfM) photogrammetry enables the cost-effective digital characterisation of seismic- to sub-decimetre-scale geoscientific samples. The technique is commonly used for the characterisation of outcrops, ... -
Direct Simple Shear Tests on Snow and their Relation to Slab Avalanche Formation
(Journal article, 1977)Many slab avalanches can be attributed to shear failure in a weak, thin basal layer at the slab base. A reasonable starting point for evaluation of the conditions prior to fracture is, therefore, an investigation of shear ... -
Direction Estimates for Short‐Period P‐Waves on Three‐Component Stations and Arrays
(Peer reviewed; Journal article, 2023)P‐arrival backazimuth estimates can be crucial in locating poorly constrained seismic events. Correlating short windows of the vertical waveform with corresponding windows of the radial rotation for different backazimuths ...
