Groundwater use for irrigation - a global inventory [PDF]

, 2010
Irrigation is the most important water use sector accounting for about 70% of the global freshwater withdrawals and 90% of consumptive water uses. While the extent of irrigation and related water uses are reported in statistical databases or estimated by

Surface‐Mounted Metal‐Organic Framework for the Adsorption and Sensing of Monoaromatic Pollutants in Water Using Quartz Crystal Microbalance

Advanced Materials Technologies, EarlyView.
A hydrophobic metal‐organic framework (UHMOF‐100) is grown on a quartz crystal microbalance sensor for the first time. The device enables real‐time, selective detection of monoaromatic BTEX pollutants in water, demonstrating a new strategy for creating robust chemical sensors for challenging environmental monitoring applications. Abstract Environmental

Efficient Model Calibration Using Submodels

Water Resources Research
Groundwater models tend to become increasingly detailed to accommodate increasing data availability and higher accuracy demands from stakeholders. As runtimes increase almost quadratically with the number of model cells, this makes the models ever more ...

Molecular Simulation of Functionalized Covalent Organic Framework Membranes for Inorganic Salt Separation

Advanced Theory and Simulations, EarlyView.
Six functionalized TpPa‐based covalent organic frameworks (COFs) are characterized using nonequilibrium molecular dynamics simulations to assess water permeance and salt rejection. The TpPa‐SO3H COF membrane achieves the highest sodium sulfate rejection (>98%) while maintaining relatively high water permeance compared to commercial nanofiltration ...

Global Evidence of the Unimodal Response of Ecosystem Respiration to Soil Moisture

Advanced Science, EarlyView.
Using global eddy covariance observations and a field experiment, this paper provides compelling evidence for the widespread unimodal relationship between soil moisture and ecosystem respiration and its water adaptation. Such knowledge facilitates understanding of soil moisture in affecting respiratory carbon emissions and has the potential to improve ...
