WebbAlthough it is generally well known that water repellent soils have distinct preferential flow patterns, the physics of this phenomenon is not well understood. In this chapter, we show that water repellency affects the soil water contact angle and this, in turn, has a distinct effect on the constitutive relationships during imbibing.

WebbWhen soil moisture is above a critical value (which is different for every soil), the water repellency effect is temporarily eliminated. When it falls below this critical value, the soil returns to a hydrophobic condition. The time taken for water to infiltrate increases for repellent soils. It takes as little as 3 to 6 % hydrophobic
