This state-of-the-art covers advances in the constitutive modelling, experimental
investigation and field measurement of suction for unsaturated soils. It consists of three …

Forest wildfires leave vast areas with burned topsoil that is water repellent, susceptible to
erosion by surface runoff and a potential source of debris flow. To mitigate post‐fire debris …

The discharge of untreated oily wastewater into the environment has serious impacts on
human health, living nature, and ecosystems and leads to significant economic losses. Many …

In an ideal unsaturated soil model, the contact angle (CA) is often determined by the sessile
drop method (SDM), or assumed without any test. However, both approaches can lead to …

Hydrophobised soils found in the superficial region of earthen infrastructure can affect the
hydrological processes of these structures. The hysteretic water-retention curve (WRC) …

Separation of oil and water is an effective technique to treat oily wastewater. For examining
the applicability of porous grains coated with hydrophobic agents (HA) as low-cost and …
