Poultry manure (PM) has become a serious environmental problem due to large scale of
industrial production and unsustainable management, causing emissions of greenhouse …

Abstract The Prediction in Ungauged Basins (PUB) initiative of the International Association
of Hydrological Sciences (IAHS), launched in 2003 and concluded by the PUB Symposium …

The original review of macropores and water flow in soils by Beven and Germann is now 30
years old and has become one of the most highly cited papers in hydrology. This paper …

Continental precipitation not routed to the oceans as runoff returns to the atmosphere as
evapotranspiration. Partitioning this evapotranspiration flux into interception, transpiration …

Europe has experienced a series of major floods in the past years which suggests that flood
magnitudes may have increased. Land degradation due to soil compaction from crop …

Headwater, or first-order, catchments are the building blocks of drainage basins. They
contribute up to half of the mean water volume and nitrogen fluxes for fourth-order and …

Research on the coupling of soil, vegetation, and hydrological processes is not only a
research hotspot in disciplines such as pedology, ecohydrology and Earth system science …

Core Ideas Understanding of preferential flow is improving, stimulated partly by new
technologies. Empirical process understanding has outstripped the capability of models to …

Field studies in watershed hydrology continue to characterize and catalogue the enormous
heterogeneity and complexity of rainfall runoff processes in more and more watersheds, in …

Preferential flow (PF) processes are governed by subsurface soil structures at various
scales. Still, model validation and mechanistic understanding of PF are very lacking. We …
