Reconnaissance‐Scale Methods for the Identification of Groundwater Discharge to Streams

Groundwater Monitoring &Remediation, EarlyView.
Abstract Identifying groundwater discharge locations is critical for understanding and monitoring groundwater contributions to streams in terms of water quantity and quality. Streams and rivers are under increasing strain from factors, including increased urbanization, agricultural land use, groundwater extraction, and climate change, which can alter ...

Higher-order internal modes of variability imprinted in year-to-year California streamflow changes

Communications Earth & Environment
Climate internal variability plays a crucial role in the hydroclimate system, and this study quantifies its predictability on streamflow in California using historical observations, climate simulations, and various machine learning (ML) models.

Water temperature and river discharge drive age‐dependent changes in brown trout (Salmo trutta) growth

Journal of Fish Biology, EarlyView.
Abstract Rivers and streams exhibit inherent variability in environmental conditions, particularly in water temperature and stream discharge. These factors can impact fish growth through both direct (i.e., physiological) and indirect (i.e., ecosystem productivity) mechanisms.

Hydro-Climatic Variability: A Characterisation and Trend Study of the Awash River Basin, Ethiopia

Hydrology, 2019
The objective of this study was to characterize, quantify and validate the variability and trends of hydro-climatic variables in the Awash River Basin (ARB) in Ethiopia using graphical and statistical methods. The rainfall and streamflow trends and their

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

Restoration Ecology, EarlyView.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

A Field Guide to Corralling the Chaos: A Planning Framework for Using Models to Guide Opportunistic Field Studies of Natural Disturbances

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Watersheds regulate biogeochemical processes and provide ecosystem services to human societies, but disturbances can fundamentally alter these processes across space and time. Determining when and where to sample to capture disturbance impacts in watersheds remains a central challenge.

Hydrologic Trends in the Upper Nueces River Basin of Texas—Implications for Water Resource Management and Ecological Health

Hydrology, 2019
Reliable water sources are central to human and environmental health. In south Texas, USA, the Nueces River Basin (NRB) directly or indirectly plays that important role for many counties.
