Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Laboratory calibration of pressure transducer-tensiometer system for hydraulic studies

, 1994
Pressure transducer-tensiometer (PTT) systems can be used to continuously monitor soil pore water pressure and the hydraulic gradient distribution in a field, and under laboratory conditions over relatively short time intervals.

Biosurfactant‐assisted recovery and remediation of hydrocarbons from oily sludge using a mobile aerated washing system

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The oil industry generates oily sludge, the accumulation of which poses a serious environmental problem. Conventional methods require high costs, specialized equipment, and qualified personnel. This waste can be treated using biosurfactants.

Micellar and Solubilization Properties of Biological Surfactant Surfactin

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.

A MICROFLUIDIC TENSIOMETER

, 2020
Recent theoretical predictions indicate that a shift in surfactant transport mechanism from diffusion controlled to kinetically controlled occurs at highly curved interfaces where the length scale is on the same order as feature sizes in microfluidic ...

Calibration of a high-suction tensiometer [PDF]

, 2008
High-suction tensiometers are able to measure suctions up to 2 MPa. Direct calibration at such high suctions requires the imposition of negative water pressures, which are difficult to achieve using facilities commonly available in soil mechanics ...
