Estimation of soil permeability

Estimation of Soil Permeability using Soil Index Properties

Permeability is a very important engineering property of soils and finds utility in a number of soil engineering problems such as yield of wells and seepage through and below the earth structures. It controls the hydraulic stability of soil masses. The permeability of soils is also required in the design of filters required to prevent piping in hydraulic structures. However, the determination o...

Effect of Persulfate Formulations on Soil Permeability

by MIAO YU, M.S. Washington State University August 2010 Chair: Richard J. Watts In situ chemical oxidation (ISCO) using persulfate is a promising technique for the remediation of soil and groundwater contaminants. Persulfate activated by iron (III)-EDTA or sodium hydroxide can accelerate the degradation of contaminants. However, in previous studies of ISCO remediation processes, the applicatio...

Graphical Estimation of Permeability Using RST&NFIS

This paper pursues some applications of Rough Set Theory (RST) and neural-fuzzy model to analysis of "lugeon data". In the manner, using Self Organizing Map (SOM) as a pre-processing the data are scaled and then the dominant rules by RST, are elicited. Based on these rules variations of permeability in the different levels of Shivashan dam, Iran has been highlighted. Then, via using a combining...

Permeability of Natural Clay Liners: Effect of Accelerated Permeability Testing on Soil Structure

A variety of clay specimens (Kaolin, Belfast Upper Boulder Clay and Belfast Sleech) were subjected to British Standards Triaxial Permeability Tests and Accelerated Permeability Tests in order to examine how the permeability predicted (under uniform effective stresses and conditions) varied depending on the testing method adopted. The specimens were then freeze-dried to preserve their post-test ...
