Groundwater use for irrigation - a global inventory [PDF]

open access: yes, 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

Too hot for comfort: Elevated temperatures influence gene expression and exceed thermal tolerance of bigmouth shiners, Ericymba dorsalis

open access: yesJournal of Fish Biology, EarlyView.
Abstract Environmental and associated ecosystem change may affect the persistence of fish species based on their ability to adapt to changing conditions, including decreasing flows and rising water temperatures. Exceeding the thermal tolerances of stream fish will likely result in a loss of ability to maintain metabolic processes.

Effects of low‐tech, process‐based restoration on riparian plant communities and soil moisture of streams in the Northern Great Plains (NGP) of the United States

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Process‐based restoration is novel in livestock production systems of the Northern Great Plains (NGP), and limited region‐specific evidence can impede adoption. We investigated the effects of methods such as beaver dam analogs (BDAs) on NGP plant communities.

Sustainable Groundwater Exploitation under Natural Conditions in Southwest Ghana [PDF]

open access: yes, 2005
Groundwater has been recognised as the most cost-effective option of safe water supply to rural communities in Ghana. The demand for potable water has led to the drilling of a large number of boreholes in many parts of the country.

Review of Water Supply, Treatment and Distribution: Overcoming Challenges for Sustainable Management

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT Water management faces increasing challenges driven by population growth, accelerated urbanization and climate change, demanding integrated and sustainable approaches to ensure the preservation of water resources. Water scarcity and rising demand intensify the vulnerability of various regions, threatening both water supply and environmental ...

Estimation of aquifer lower layer hydraulic conductivity values through base flow hydrograph rising limb analysis [PDF]

open access: yes, 2010
The estimation of catchment-averaged aquifer hydraulic conductivity values is usually performed through a base flow recession analysis. Relationships between the first time derivatives of the base flow and the base flow values themselves, derived for ...

PFAS Vadose Zone Mass Discharge at an AFFF‐Impacted Site: 1. Validation Based on a Multiple Lines‐of‐Evidence Approach

open access: yesRemediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Questions have recently been raised about the suitability of using porewater samples collected with suction lysimeters to estimate per‐ and polyfluoroalkyl substances (PFAS) mass discharge in the vadose zone. Multiple lines of evidence were evaluated to determine if porewater samples collected during a data gaps investigation in the former ...
