When it comes to soil and water, predictability is important—but difficult. Soil scientists have struggled with accurately measuring water flow through soil for years. Even the smallest soil details ...

Interestingly, preferential flow occurrence was more frequent in downslope areas than upslope, due to the spatial variation in soil hydraulic properties. In slopes with thicker soil, a negative ...

Preferential water flow denotes the rapid and non-uniform movement of water through discrete pathways in the soil, bypassing the finer pore network of the soil matrix. These pathways include ...

The two major flow mechanisms in the vadose zone are uniform flow and preferential flow. Both types of flow occur often simultaneously, but have considerably different consequences for water flow and ...
