Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Degradation of Seasonally Frozen Ground in the Three–River Source Region and Its Correlation Impact Within Precipitation–Runoff Process

International Journal of Climatology, EarlyView.
This study reveals how climate change alters the water cycle in the Three Rivers Source region by degrading its important ‘solid groundwater’ (seasonally frozen ground). We found that runoff response varies by watershed and the role of permafrost decreases sharply, making water supply more dependent on rainfall and becoming increasingly vulnerable ...

Solute Evidence for Hydrological Connectivity of Geographically Isolated Wetlands

, 2018
Hydrological connectivity describes the water‐mediated transfer of mass, energy, and organisms between landscape elements and is the foundation for understanding how individual elements such as wetlands and streams integrate to support ecosystem services

Temporal variability of nitrate transport through hydrological response during flood events within a large agricultural catchment in south-west France [PDF]

, 2010
The temporal variability of nitrate transport was monitored continuously in a large agricultural catchment, the 1110 km2 Save catchment in south-west France, from January 2007 to June 2009.

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

Journal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

Deterministic influences exceed dispersal effects on hydrologically‐connected microbiomes [PDF]

Environmental Microbiology, 2016
Summary Subsurface groundwater‐surface water mixing zones (hyporheic zones) have enhanced biogeochemical activity, but assembly processes governing subsurface microbiomes remain a critical uncertainty in understanding hyporheic biogeochemistry.

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

Journal of Quaternary Science, EarlyView.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape
