Preferential flow is often thought of as a spatially and temporally highly variable and random
process and, as such, essentially unpredictable. This chapter discusses the experimental …

Persistence of subsoil compaction was investigated in a field experiment in southern
Sweden. The investigation compared two treatments (control and compaction by four passes …

The aims of this study were to develop a method to determine the spatial and temporal
characteristics of agricultural non-point source (ANPS) pollution loads at the basin scale …

Preferential infiltration occurs widely in loess deposits and has a major impact on water
movement and redistribution. However, preferential infiltration is a complex process, and …

Salt dissolved in soil water is transported upward to the soil surface through capillary rise
from shallow groundwater, leading to salt accumulation near the surface and salinization of …

The objectives of this study were to examine applicability of the iodine–starch method to
visualize heterogenous soil water flow and to investigate relationships between soil water …

Preferential flow in natural unsaturated soils is common, but difficult to characterize and
predict. The major objective of this research is to investigate the preferential flow patterns …

Distributed/semi-distributed hydrological models are often associated with geographic
information systems (GIS) to identify non-point source (NPS) priority management areas …

The quality of surface water and groundwater is closely related to flow paths in the vadose
zone. Therefore, dye tracer studies are often carried out to visualise flow patterns in soils …

Study region The study region is a typical desert oasis ecotone of the Hexi Corridor,
Northwest China. Study focus Based on four years of in situ observational data of soil water …
