Sensitivity of Seismic Attenuation and Phase Velocity to Intrinsic Background Anisotropy in Fractured Porous Rocks: A Numerical Study
(Blackwell Publishing, 2017-10-09)
Many researchers have analyzed seismic attenuation and velocity dispersion due to wave-induced fluid flow (WIFF) related to the presence of fluid-saturated fractures embedded in an isotropic porous background. Most fractured ...
Finite-element harmonic experiments to model fractured induced anisotropy in poroelastic media
(Elsevier, 2015-01)
Fractures in a fluid-saturated poroelastic-Biot-medium can be modeled as very thin highly permeable and compliant layers within a porous background. A Biot medium containing a dense set of aligned fractures behaves as an ...
Large-scale ecological restoration of high-diversity tropical forests in SE Brazil
(ELSEVIER SCIENCE BV, 2011)
The complex interactions among endangered ecosystems, landowners` interests, and different models of land tenure and use, constitute an important series of challenges for those seeking to maintain and restore biodiversity ...
Modeling Forced Imbibition Processes and the Associated Seismic Attenuation in Heterogeneous Porous Rocks
(Blackwell Publishing, 2017-11)
Quantifying seismic attenuation during laboratory imbibition experiments can provide useful information toward the use of seismic waves for monitoring injection and extraction of fluids in the Earth's crust. However, a ...
A functional–structural plant model that simulates whole- canopy gas exchange of grapevine plants (Vitis vinifera L.) under different training systems
(Oxford University Press, 2020-09)
Background and Aims: Scaling from single-leaf to whole-canopy photosynthesis faces several complexities related to variations in light interception and leaf properties. To evaluate the impact of canopy strucuture on gas ...
Saturation hysteresis effects on the seismic signatures ofpartially saturated heterogeneous porous rocks
(Blackwell Publishing Ltd, 2019-09-13)
Experimental evidence indicates that the spatial distribution of immiscible pore fluids in partially saturated media depends on the flow history and, thus, exhibits hysteresis effects. To date, most works concerned with ...
