The objective of this study is to demonstrate how fault dynamics may naturally be placed in the context of incremental stress theory, rock textural evolution modeling and standard conservation laws. Casting the fault dynamics problem in this framework naturally introduces rock memory for failure, fluid pressure effects and the autonomous nature of fault evolution. Poroelasticity, nonlinear viscosity and gouge are combined in an incremental stress rheology approach to examine the effect of changes in particle size distribution on fluid pressure in fault zones.

Explicit representation of spatial heterogeneity in reactive transport models: application to bioirrigated sediments
Meile, C; Tuncay, Kağan; Van Cappellen, P (Elsevier BV, 2003-05-01)
Existing reactive transport models represent aquatic sediments as one-dimensional systems. These models account for the predominantly vertical chemical gradients recorded by traditional pore water and solid sediment sampling techniques (e.g., cores, dialysis samplers). However, advances in sampling techniques, including the rapid development of in situ microprofilers, are providing increasingly detailed data sets, which highlight the laterally heterogeneous nature of the water-sediment interface. In particu...
Assessment of Point-Source Stochastic Simulations Using Recently Derived Ground-Motion Prediction Equations
Akkar, Dede Sinan; Yenier, Emrah (Seismological Society of America (SSA), 2009-12-01)
The simplicity of the point-source stochastic simulation method makes it one of the most appealing tools for the quantification of ground motions for seismic hazard related studies. In this article, we scrutinize the limitations of this technique in terms of fundamental geophysical model parameters. To achieve this objective, we use the estimations of recent Next Generation Attenuation (NGA) and European empirical ground-motion models that are based on global strong-motion databases. The generated synthetic...
Estimation of Hardgrove grindability index of Turkish coals by neural networks
Ozbayoglu, Gulhan; ÖZBAYOĞLU, AHMET MURAT; Ozbayoglu, M. Evren (Elsevier BV, 2008-01-31)
In this research, different techniques for the estimation of coal HGI values are studied. Data from 163 sub-bituminous coals from Turkey are used by featuring I I coal parameters, which include proximate analysis, group maceral analysis and rank. Nonlinear regression and neural network techniques are used for predicting the HGI values for the specified coal parameters. Results indicate that a hybrid network which is a combination of 4 separate neural networks gave the most accurate HGI prediction and all of...
Sensitivity Study of Hydrodynamic Parameters During Numerical Simulations of Tsunami Inundation
Ozer, Ceren; Yalçıner, Ahmet Cevdet (Springer Science and Business Media LLC, 2011-11-01)
This paper describes the analysis of a parameter, "hydrodynamic demand,'' which can be used to represent the potential for tsunami drag force related damage to structures along coastlines. It is derived from the ratio of drag force to hydrostatic force caused by a tsunami on the structure. It varies according to the instantaneous values of the current velocities and flow depths during a tsunami inundation. To examine the effects of a tsunami in the present study, the analyses were performed using the tsunam...
Palaeomagnetic evolution of the Cankiri Basin (central Anatolia, Turkey): implications for oroclinal bending due to indentation
Kaymakcı, Nuretdin; Langereis, Cor; White, Stan; van Dijk, Paul (Cambridge University Press (CUP), 2003-05-01)
Palaeomagnetic data in combination with palaeostress data and anisotropy of magnetic susceptibility orientations are utilized to develop a tectonic evolutionary model for the Early Tertiary part of the Omega(omega)-shaped Cankiri Basin (Turkey). The results reveal clockwise rotations in the northeast and anticlockwise rotations in the west and southeastern corner of the basin. The magnetic inclinations indicate a northward drift of the Cankiri Basin and support an indentation model for the Kirsehir Block. I...
