Abstract text:
This paper aims to highlight the relationship between soil particles morphology (shape, size and surface area) and hydraulic properties (hydraulic conductivity (saturated and unsaturated) and soil suction). Determination of morphological characteristics of soil particles was achieved by: a) size analysis and b) SEM microscopic analysis type. Determination of soil hydraulic properties was performed by laboratory methods: for hydraulic conductivity was used the constant-head method and the falling head method and suction was determined using the sandbox, sand/kaolin box and pressure membrane apparatus.
Key Words:
hydraulic conductivity; suction; particle size analysis; micro-scopic analysis.
