Protecting or restoring aquatic ecosystems in the face of growing anthropogenic pressures
requires an understanding of hydrological and biogeochemical functioning across multiple …

Headwater catchments are the fundamental units that connect the land to the ocean.
Hydrological flow and biogeochemical processes are intricately coupled, yet their respective …

Spatially explicit knowledge of the origins of water resources for ecosystems and rivers is
challenging when using tracer data alone. We use simulations from a spatially distributed …

Environmental flows assessment science focuses largely on defining how modified flow
regimes (from water infrastructure and direct water abstraction) can be managed to conserve …

The science and practice of environmental flows have advanced significantly over the last
several decades. Most environmental flow approaches require quantifying the relationships …

Catchment science plays a critical role in the protection of water resources in the face of
ongoing changes in climate, long‐range transport of air pollutants, and land use. Addressing …

Nature‐based solutions for water‐resource challenges require advances in the science of
ecohydrology. Current understanding is limited by a shortage of observations and theories …

Landscapes receive water from precipitation and then transport, store, mix, and release it,
both downward to streams and upward to vegetation. How they do this shapes floods …

The science of hydrology is on the threshold of major advances, driven by new hydrologic
measurements, new methods for analyzing hydrologic data, and new approaches to …

Globally, many different kinds of water resources management issues call for policy-and
infrastructure-based responses. Yet responsible decision-making about water resources …
