Earth–rock dams are typical soil–rock mixtures with high heterogeneity. Mastering the effect of dam heterogeneity on seismic wavefields is premise accurately detecting hidden risks in dams. In this paper, based mixture characteristics actual dams, a model that can reflect established through local segmentation and reassignment random disturbances. The influence area size described. wavefield nu...

The Mesopotamian spiny eel, Mastacembelus mastacembelus, an endemic freshwater fish restricted to the Euphrates and Tigris river drainages of Mesopotamian, its related taxa in Afrotropica South Asia present suitable elements for studies evolutionary history mastacembelids across these heterogeneous areas. To understand clarify geographic variation eel from Persian Gulf basin, we investigated mo...

The Benínar Dam, located in Southeastern Spain, is an earth-fill dam that has experienced filtration issues since its construction 1985. Despite the installation of various monitoring systems, data collected are sparse and inadequate for dam’s lifetime. present research integrates Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) modeling to validate this dam, opening way enhan...

the main role ofcore in earth dams is to reduce and control the seepage flow through the dam. in order to achieve this purpose, the core material is usually selected from pure or mixed clays.due to very small coefficient of permeability, the clay cores can prevent water leakageeasily. however, pore water pressures developed inside the core during construction, can not be dissipated quickly. as ...

The parameters of the constitutive model, the creep model, and the wetting model of materials of the Nuozhadu high earth-rockfill dam were back-analyzed together based on field monitoring displacement data by employing an intelligent back-analysis method. In this method, an artificial neural network is used as a substitute for time-consuming finite element analysis, and an evolutionary algorith...

30 Abstract—The blessings of hyperspectral remote sensing are manifold and it has enabled researchers to locate, map and identify different materials on the surface of Earth. Hyperspectral remote sensing play a key role in mineral mapping activities and it can be a much powerful and cost effective tool for mineral development activities in a developing country like Pakistan where there are rich...

This paper introduces an accurate, fast, and applicable method for optimization of slip surfaces in earth slopes. Using Genetic Algorithm (GA), which is one of the modern and non-classic optimization methods, in conjunction with the well -known Bishop applied method, the optimum slip surface in an earth slope is investigated and its corresponding lowest safety factor is determined. Investigati...
