The time that water takes to travel through the terrestrial hydrological cycle and the critical
zone is of great interest in Earth system sciences with broad implications for water quality …

While the concept of connectivity has gained popularity in fields like hydrology and ecology,
little agreement exists on its definition, which hinders its use in both scientific and legal …

The shallow and deep hypothesis suggests that stream concentration‐discharge (CQ)
relationships are shaped by distinct source waters from different depths. Under this …

Groundwater levels are typically measured at only a limited number of points in a catchment.
Thus, upscaling these point measurements to the catchment scale is necessary to determine …

The role of landscape topography in mediating subsurface water availability and ultimately
tree transpiration is still poorly understood. To assess how hillslope position affects tree …

Catchment response to precipitation is often investigated using two-component isotope-
based hydrograph separation, which quantifies the contribution of precipitation (ie, event …

Hillslope-stream connectivity significantly affects streamflow and water quality responses
during rainfall and snowmelt events, but is difficult to quantify. One approach to quantify …

Abstract Study region Beijing Plain, China Study focus The traditional zoning of groundwater
systems relies on lithological characteristics and hydraulic connections. However, the …

It is generally assumed that, in humid climates, the groundwater table is a subdued copy of
the surface topography. However, the general groundwater table is unlikely to be affected by …

Subsurface runoff represents the main pathway of nitrate transport in hilly catchments. The
magnitude of nitrate export from a source area is closely related to subsurface hydrological …
