Multicompartment and multiscale long-term observation and research are important
prerequisites to tackling the scientific challenges resulting from climate and global change …

The hydraulic conductivity (K) of the streambed is an important variable influencing water
and solute exchange between streams and surrounding groundwater systems. However …

This paper presents results on the spatiotemporal dynamics of the coupled water flux (v) and
nitrogen fluxes (fN= v [N], where [N] is the concentration of a dissolved N species) through a …

The hydrologic sciences must play a major role in improving our understanding of the
transport and fate of the vast amount of reactive nitrogen that is being added to the …

Underlying questions that are central to field studies of the groundwater–surface water
interaction are the extent of error in means and spatial distributions of streambed attributes …

Water is essential to life for humans and their food crops, and for ecosystems. Effective water
management requires tracking the inflow, outflow, quantity and quality of ground-water and …

The increasing expression of human activity, climate variability, and climate change on
humid, terrestrial hydrologic systems has made the integrated nature of large river basins …

Despite a long history of synergy, current techniques for integrating Geographic Information
System (GIS) software with hydrologic simulation models do not fully utilize the potential of …

The analytic-element method (AEM) is an appealing technique for modeling steady-state
groundwater flow at the supraregional scale (defined here as> 10,000 km 2) because the …

The wealth of publicly available hydrologic data from observation networks, satellite-based
sensors, global-scale modeling efforts, and digitized paper maps provide an excellent base …
