An increase in the flow velocity in flowthrough large porous media and deflection of flow regime from Darcy law causes a nonlinear relationship between hydraulic gradient and pore velocity of media. So many investigations have done previously in such Medias. One of the most important subjects in flowthrough large porous media is relationship between friction coefficient and flow characteristics...

Computational modeling plays a significant role in the design of rockfill dams. Various constitutive soil parameters are used to such models, which often involve high uncertainties due complex structure dams comprising various zones different parameters. This study performs an uncertainty analysis and global sensitivity assess effect on behavior dam. A Finite Element code (Plaxis) is utilized f...

The establishment of relationships between the shear wave velocity (V s ) and other geotechnical parameters rockfills under large strains (e.g., oedometer-constrained modulus, M oedo , tangent elastic E t is a significant step toward precise modeling earth structure stress–strain behavior. In this study, four specimens reconstituted from rockfill used for Romaine-2 dam construction were investi...

Dams and ponds as engineering structures pose various risks during design, construction operation. Deformation in dams, slope stability problems or excessive pore pressure can cause serious damage that cannot be prevented. It is critical to position these areas correctly evaluate the potential quantitatively. In rockfill work needs done planning project phase, especially on infiltration safety....

Stress relaxation properties have a significant impact on the performance of polyvinyl chloride (PVC) geomembranes (GMBs) at peripheral joints membrane faced rockfill dam (MFRD). This paper presents fractional order viscoelastic model (FOVM) to measure stress as function time. Model parameters were obtained by best fit results from wide-width strip tensile tests conducted three rates and initia...

Infrastructures play an important role in urbanization and economic activities but are vulnerable. Due to unavailability of accurate subsurface infrastructure maps, ensuring the sustainability resilience often poorly recognized. In current paper a 3D topographical predictive model using distributed geospatial data incorporated with evolutionary gene expression programming (GEP) was developed ap...
