Effects of CO2 Injection on the Seismic Velocity of Sandstone Saturated with Saline Water
Biot-Gassmann Theory CO2 Geological Sequestration
2013/3/11
Geological sequestration (GS) of carbon dioxide (CO2) is considered as one of the most promising technologies to reduce the amount of anthropogenic CO2 emission in the atmosphere. To ensure success of...
Exploring Trends in Microcrack Properties of Sedimentary Rocks: An Audit of Dry and Water Saturated Sandstone Core Velocity–Stress Measurements
Compliance Ratio Microcrack Properties Saturated Stress Dependent Velocities Ultrasonic
2013/3/11
Stress dependent rock physics models are being used more routinely to link mechanical deformation and stress perturbations to changes in seismic velocities and seismic anisotropy. In this paper, we in...
EnKF assimilation of simulated spaceborne Doppler observations of vertical velocity: impact on the simulation of a supercell thunderstorm and implications for model-based retrievals
EnKF velocity
2010/1/27
Recently, a number of investigations have been made that point to the robust effectiveness of the Ensemble Kalman Filter (EnKF) in convective-scale data assimilation. These studies have focused on the...
Variations of phase velocity and gradient values of ULF geomagnetic disturbances connected with the Izu strong earthquakes
phase velocity gradient values ULF geomagnetic disturbances Izu strong earthquakes
2009/12/11
Results of study of anomaly behavior of amplitudes, phase velocities and gradients of ULF electromagnetic disturbances (F = 0.002 – 0.5 Hz) before and during a seismic active period are presented. Inv...
Is flow velocity a significant parameter in flood damage modelling?
flow velocity significant parameter flood damage modelling
2009/12/8
Flow velocity is generally presumed to influence flood damage. However, this influence is hardly quantified and virtually no damage models take it into account. Therefore, the influences of flow veloc...
Near surface shear wave velocity in Bucharest,Romania
Near surface shear wave velocity Bucharest
2010/1/4
Bucharest, the capital of Romania with nearly 2 1/2 million inhabitants, is endangered by the strong earthquakes in the Vrancea seismic zone. To obtain information on the near surface shear-wave veloc...
On the effects of vertical air velocity on winter precipitation types
effects vertical air velocity winter precipitation types
2009/12/30
The various precipitation types formed within winter storms (such as snow, wet snow and freezing rain) often lead to very hazardous weather conditions. These types of precipitation often occur during ...
Flow velocity in rivers has a major impact on residence time of water and thus on high and low water as well as on water quality. For global scale hydrological modeling only very limited information i...
Measurements of debris flow velocity through cross-correlation of instrumentation data
Measurements debris flow velocity cross-correlation instrumentation data
2009/12/25
Detection of debris flow occurrence can be efficiently obtained through different types of sensors. A pair of ultrasonic sensors placed at a known distance from each other along a torrent have been us...
