FEL4 – Soil Moisture Suction Sand Table

Primarily for the derivation of soil moisture characteristic curves, the FEL4 helps in understanding the principle of water retentivity and its relationship with soil moisture levels.

Description

Primarily for the derivation of soil moisture characteristic curves, the FEL4 helps in understanding the principle of water retentivity and its relationship with soil moisture levels.

The equipment consists of a freestanding circular tank filled with saturated sand (not supplied).

Equilibrated soil samples placed on the sand are then subjected to a known variable suction range of 0-800mm of water.

The suction is applied by means of a buried porous pipe and an associated sliding control chamber. In order to maintain the suction an uninterrupted low volume water supply is required.

A lightweight cover is provided to prevent evaporative water loss during experiments and the table is large enough to permit the simultaneous evaluation of several samples.
