Process-based hydrological models have a long history dating back to the 1960s. Criticized
by some as over-parameterized, overly complex, and difficult to use, a more nuanced view is …

In spite of trying to understand processes in the same spatial domain, the catchment
hydrology and water quality scientific communities are relatively disconnected and so are …

Integrated, process‐based numerical models in hydrology are rapidly evolving, spurred by
novel theories in mathematical physics, advances in computational methods, insights from …

There are a growing number of large‐scale, complex hydrologic models that are capable of
simulating integrated surface and subsurface flow. Many are coupled to land‐surface energy …

Surface flow and subsurface flow constitute a naturally linked hydrologic continuum that has
not traditionally been simulated in an integrated fashion. Recognizing the interactions …

In arid regions, water resources are under immense pressure and multiple stresses.
Excessive use of water resources without proper management occurs in the present …

In arid and semi-arid areas where agriculture competes keenly with ecosystem for water,
integrated management of both surface water (SW) and groundwater (GW) resources at a …

Integrated surface water‐groundwater modeling can provide a comprehensive and coherent
understanding on basin‐scale water cycle, but its high computational cost has impeded its …

The structural and hydrological complexity of hard rock systems (HRSs) affects dynamics of
surface–groundwater interactions. These complexities are not well described or understood …

Water transit times and flow pathways are crucial elements in characterizing catchment
hydrologic response. Understanding their variability in space and time sheds light on the link …
