What is Amoozemeter?

What is an Amoozemeter? The Compact Constant Head Permeameter, also known as the Amoozemeter, is a revolutionary piece of field equipment that provides the means to collect data for determining in-situ saturated hydraulic conductivity (Ksat) of the vadose (unsaturated) zone easily and conveniently.

How does a Permeameter work?

PERMEAMETER METHODS The soil sample is placed in a chamber that is usually cylindrical and outfitted with a porous plate at both ends, which allows only water to pass through the chamber. The soil sample is fully saturated with water that is deaerated to prevent entrapment of air in the pores.

How does a tension Infiltrometer work?

Tension infiltrometers are designed to measure the unsaturated hydraulic properties of soils. By maintaining a small negative pressure (or tension) on the soil as water is infiltrating, water will not enter the large cracks or wormholes as much, but will infiltrate through the soil matrix.

Why porous discs are used in permeameter?

What does high hydraulic conductivity mean?

DEFINITIONS OF HYDRAULIC CONDUCTIVITY In theoretical terms, hydraulic conductivity is a measure of how easily water can pass through soil or rock: high values indicate permeable material through which water can pass easily; low values indicate that the material is less permeable.

How do you calculate infiltration rate?

Compute infiltration rate (I) by dividing water depth (H) by elapsed time (t). I = H/t 5.

How does a permeameter work?

What does a permeameter measure?

The disc permeameter is a field instrument used for measuring water infiltration in the soil, which is characterized by in situ saturated and unsaturated soil hydraulic properties. It is mainly used to provide estimates of the hydraulic conductivity of the soil near saturation.

How do you read hydraulic conductivity?

Values to the right indicate saturated conductivity values. Values to the left indicate unsaturated values. The poorly structured clayey soil (lower line) has a saturated conductivity much lower than the sandy soil. This is because the clayey soil consists of small pores and the flow paths are more restricted.

How do you calculate hydraulic conductivity?

Some of the common methods for calculating Hydraulic Conductivity are described below: Hydraulic conductivity is the coefficient k in the Darcy’s law v = ki, where v is the velocity and i the hydraulic gradient. Hydraulic conductivity values can be determined in the laboratory using disturbed soil samples.
