ALLGEMEINE BESCHREIBUNG

The Demonstration Infiltration Unit, “PEDI”, is a small scale unit designed to demonstrate infiltration processes and to understand the effects of soil texture and structure on infiltration and the effects of existing moisture conditions of the soil on infiltration.

This unit comprises three transparent graduated cylinders in which soil samples are placed. Water poured onto the soil surface can then be observed as it infiltrates the sample. Each cylinder features a graduated scale so that observations may be quantified. The cylinders have a permeable perforated plate at the bottom that retains the soil samples while allowing the water to drain through and facilitates drainage without undue soil loss.

Placed under the cylinders, there is a tank to collect the water and the smaller soil particles under study.

Water is poured onto the soil surface into each cylinder and its progress through the samples can be observed.
