Heavy vibratory plate compaction is an efficient technique for improvement of granular soils. However, its practical application limited by insufficient knowledge about the process and optimum procedure execution. In this study, tests were conducted in field with a 40.5-ton heavy compactor. The site consisted partially saturated, overconsolidated medium-dense silty sand sandy silt. Such conditi...

This study investigated the efficiency of two types of media, namely, gravels and sand for their nutrient removal capabilities from wastewater. Different levels of sand depths were also experimented for their removal efficiencies. And for this purpose three laboratory scale vertical upflow constructed wetlands (S1, S2, S3) were established at PHE Laboratory, MNIT, Jaipur. S1was filled with two ...

Loess and loess-like soil formations are distributed in 3 regions across Mongolia. The lower part of the Orkhon Selenge river basin North Mongolia is main loess area another two located east Mongolia, Onon Ulz basins Khalka Gol area. Loess-like covers a total 109,000 sq.km or 6.95 per cent territory country. properties have been studied on basis 8 sections 83 samples. Fine sand fraction predomi...

The results of fishery investigations are used to estimate the catch size, times fish are caught, and future stocks in the fish culture industry. In Tokoro, Japan, scallop farms for fisheries are found on gravel and sand seabeds. The seabed images are used for fishery investigations, which are absolutely necessary to visually estimate the amount of scallops. However, there is no automatic techn...

Light penetration through a Drummer silty clay loam and a Broomfield sand was measured spectrophotometrically and biologically. The spectrophotometric measurements showed that less than 1% of the incident light penetrated 2.2 millimeters at any wavelength between 350 and 780 nanometers for ped sizes up to 1 millimeter. Biological measurements with light-sensitive lettuce (Lactuca sativa) seeds ...

Magnetic Resonance Imaging (MRI) can be used for 3D analysis of small-scale porous media structure and internal flow-related processes. It offers notable advantages over traditional sediment sampling (e.g. cores or surface-based scanning) as it is capable of high spatio-temporal resolution of the full 3D volume, including the sub-surface. Similarly, compared to X-Ray tomography, the extensive c...

Groundwater is an important factor of slope stability, and 90% of slope failures are related to the influence of groundwater. In the past, free surface calculations and the prediction of water inflow were based on Darcy's law. However, Darcy's law for steady fluid flow is a special case of non-Darcy flow, and many types of non-Darcy flows occur in practical engineering applications. In this pap...

Most of the public roads that are being built and reconstructed in Uzbekistan today involve using a cement-treated or reinforced crushed stone-gravel-sand mixture for upper base layer.In process quality control construction work, several difficulties arise with assessing this material's strength.The article deals issue determining model predicting tensile strength during bending treated cement ...

conventional investigations on the behavior of reinforced and unreinforced soils are often investigated at the failure point. in this paper, a new concept of comparison of the behavior of reinforced and unreinforced soil by estimating the strength and strength ratio (deviatoric stress of reinforced sample to unreinforced sample) at various strain levels is proposed. a comprehensive set of labor...
