A methodological framework to determine optimum durations for the construction of soil water characteristic curves using centrifugation

Irish Journal of Agricultural and Food Research, 2016
During laboratory assessment of the soil water characteristic curve (SWCC), determining equilibrium at various pressures is challenging. This study establishes a methodological framework to identify appropriate experimental duration at each pressure step

An Electrowetting Pump

Advanced Functional Materials, EarlyView.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

One-stage Bayesian experimental design optimization for measuring soil-water characteristic curve

Yantu gongcheng xuebao, 2023
The direct measurements of soil-water characteristic curve (SWCC) are often costly and time-consuming. Therefore, only a limited number of test data can be obtained from a single SWCC test, based on which the estimated SWCC inevitably produces ...

A Simple Model for Estimating the Hydraulic Conductivity of Unsaturated Soil

Applied Sciences
Describing the hydraulic conductivity of unsaturated soil is very important in predicting water transport. Most current models have complex forms and generally need to be calibrated by the measured unsaturated hydraulic conductivity curve. A simple model,

Soil-Water Characteristic Curve Model Based on Particle Size Distribution and Pellicular Water [PDF]

长江科学院院报
Traditional models for predicting soil-water characteristic curve (SWCC) based on particle size distribution curve require segmentation of the curve when calculating water content and often neglect the pellicular water (also known as film water) content ...
