A fluid flow device for determining fluid flow rates in soils includes a conduit for receiving a fluid. The conduit has a reduced channel portion to form a reduced channel portion which amplifies the fluid flow rate of the fluid. A sensor device is coupled in sensing relation relative to the conduit and configured for measuring the amplified fluid flow rate as the fluid flows through the reduced channel portion.

The present invention is an apparatus and method for calibrating a downward viewing image acquisition system. The apparatus comprises a calibration panel with calibrative material of known reflectivity. The calibrative material coats the panel surface or is pulled across its surface or pulled across its frame so as to maintain a consistent reflectivity and/or emissivity. A housing is provided which protects the calibration panel from the deteriorative effects of natural elements. The housing alternately exposes the calibration panel to the downward viewing image acquisition system as a calibration exposure and covers the calibration panel after the calibration exposure.

Oil is detected in the presence of water by placing a translucent, porous body of hydrophobic material in contact with the oil and water and detecting the amount by which light incident on the body is attenuated on propagation through the body.
