Keywords: Groundwater seepage Pedotransfer function ROSETTA Seepage erosion Uncertainty analysis s u m m a r y Research has suggested that streambank seepage can be an important mechanism of bank instability; however, limited information is available on the level of soil characterization necessary to accurately predict seepage gradient forces and erosion. The objective of this research was to q...

OBJECTIVE The ethanol lock technique has shown great potential to eradicate organisms in biofilms and to treat or prevent central venous catheter related infections. Following instillation of ethanol lock solution, however, the inherent density gradient between blood and ethanol causes gravity induced seepage of ethanol out of the catheter and blood influx into the catheter. Plasma proteins so ...

For risk associated with storage of CO2 under the Earth's surface, the impervious cap is one of the most significant factors. Geological structures such as faults can provide conduits for CO2 to escape through the cap. When conductive faults intersect the storage formation and overlying permeable layers, CO2 leaks may exhibit three distinct behaviors: initial upward migration of fluids through ...

We present a constructive proof that anyonic magnetic charges with fluxes in a non-solvable finite group can perform universal quantum computations. The gates are built out of the elementary operations of braiding, fusion, and vacuum pair creation, supplemented by a reservoir of ancillas of known flux. Procedures for building the ancilla reservoir and for correcting leakage are also described. ...

Structural diseases are the main threats to safety and daily operation maintenance of cable channels. Through statistical analysis 255 channel structural nationwide, distribution characteristics were studied, seven types structures including cracks, seepage, displacement/deformation, material degradation, siltation, cavity damage revealed. The results show that water leakage, siltation cracks m...

The water conservancy project is an important infrastructure to ensure people’s living standards, which reflected in the protection of lives and property by effectively resisting floods. anti-seepage technology plays a significant role affecting construction quality projects. Under current strong supervision projects, relevant personnel should pay more attention application technology. From per...

Abstract One of the most important issues in earth dams is control rate seepage from foundation and dam bodies. Due to site dams, increase creep length reduce seepage, there are several methods for sealing reservoir that construction cut-off wall under clay core one effective methods. In this study, pore water pressure Eyvashan dam, comparison instrument results with numerical analysis and, fin...

Shale oil reservoirs are characterized by low porosity and ultra-low permeability, hydraulic fracturing technology is needed to realize industrial flow. The sand-filled fractures formed in the shale process bedding developed reservoir itself interact form a fracture network system, which main migration channel for production. Studies have shown that higher degree of development, stronger stress...

Seepage-face boundaries are common features of unconfined ground water flow. These boundaries exist at the intersection of an unconfined aquifer and a surface water body such as a lake, river, or wetland. The existence of a seepage-face boundary is necessary to provide a physical transition between the internal water-table boundary and the external equipotential boundary when an unconfined aqui...
