Detecting sources of water leakage in fractured limestone: Case study in Mokattam District, Egypt

Water Science
The paper investigates the sources of water leakage in Mokattam, Cairo, Egypt. It is considered a high-risk zone for landslides due to the presence of problematic soil, topography, and water conditions. The objective is to mitigate the negative impact of

Correcting Apparent Priming Bias Unveils Fertilizer Nitrogen‐Risk Archetypes of Surplus and Depletion Across Asian Rice Systems

Advanced Science, EarlyView.
Correcting the apparent priming effect resolves systematic biases in Asian rice fertilizer nitrogen accounting. Net soil retention drops below 7%, while 48% of fertilizer escapes, inflicting US$98.53 billion in annual reactive‐nitrogen damages. High‐resolution mapping uncovers N‐risk archetypes across 42% of the rice area, delivering a spatially ...

A Coupled Hydro‐Mechanical Modeling Framework to Concurrently Simulate Coal Seam Gas Induced Subsidence and Groundwater Impacts

Water Resources Research
Land subsidence has been extensively studied and modeled in the context of conventional petroleum or water extraction. New challenges arise to model subsidence caused by coal seam gas (CSG) depressurization. CSG‐induced subsidence is a result of multiple

Reconciling contradictory narratives of landscape change using the adaptive cycle: a case study from southeastern Australia

Ecology and Society, 2016
This paper addresses the methodological challenge of exposing and reconciling contradictory narratives of change in a social-ecological system (SES). Our research occurred in the Ovens Valley in southeastern Australia.

Metagenomic Association Uncovers Host Genotype‐Structured Rhizobacterial Networks and Novel Taxa That Enhance Soybean Salt Tolerance

Advanced Science, EarlyView.
An STI‐guided metagenomic association framework links soybean salt‐tolerance phenotypes with rhizosphere microbiome composition and network organization in natural saline soils. The approach identifies candidate beneficial taxa, including Thalassospira xiamenensis, and provides an efficient strategy for mining stress‐protective microbes from native ...

Groundwater flood or groundwater-induced flood? [PDF]

Quarterly Journal of Engineering Geology and Hydrogeology, 2012
A number of ‘groundwater flood’ events have been recorded over the Chalk aquifer in southern England since the 1994 occurrence at Chichester, Sussex. Reporting of this event and subsequent groundwater floods indicates that there are two types of groundwater flood event. Type 1 is the true groundwater flood in which the water table elevation rises above

Nanowires Reinforce Oriented Macroporous Aerogels for Rapid Uranium Removal from Acidic Radioactive Wastewater

Advanced Science, EarlyView.
A “reinforced concrete” structural aerogel with directional microchannels is engineered for rapid uranium capture. The interconnected architecture enables ultrafast water permeation, and the nanowire reinforcement yields a 70‐fold increase in mechanical strength.
