Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Translating Across Boundaries: The Process of Integrating Forestry Into the German National Water Strategy

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Participatory processes are increasingly recognized as essential components of modern environmental governance. While much scholarly attention has been devoted to the design and implementation of such processes, less is known about the critical phase between participatory processes and final policy outputs.

The effect of using different time steps in a soil water balance model to estimate groundwater recharge in the dry zone of Sri Lanka [PDF]

open access: yes, 2010
Importance of groundwater as a natural, renewable resource is well documented. The rate of replenishment of water table (or rate of groundwater recharge) is a key issue central to sustainable development of this valuable resource.

Fracture Development Mechanism of Water‐Isolating Soil Layers During Downward Mining of Shallow‐Buried Coal Seam Groups

open access: yesEnergy Science &Engineering, EarlyView.
This study systematically investigates the fracture development mechanisms of water‐isolating soil layers under the coupled effects of repeated mining and groundwater seepage during the downward mining of shallow‐buried coal seams. The findings provide a theoretical basis for evaluating stratum stability and preventing roof water inrush.

Spatial variability of groundwater recharge - II. Factors affecting variability and taking account of it in estimating recharge [PDF]

open access: yes, 2004
The accompanying paper provided evidence to suggest that spatial variability of groundwater recharge is ‘true’ variability. This paper attempts to determine the major causes of such variability even at small distances, if there appear to be a frequency ...

Green water, wetlands, and atmospheric moisture recycling ‐ An emerging new paradigm for grassland science

open access: yesGrassland Research, EarlyView.
The importance of green water in water resource management. Conceptual classification of terrestrial water components highlighting the central role of green water in land‐atmosphere interactions. This schematic distinguishes green water (soil moisture available for plant uptake and evapotranspiration) from blue water (surface water, groundwater, and ...

Transforming Agricultural Water Management Through the Water–Energy–Food Nexus: Trends, Opportunities, Barriers and Solutions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Agricultural water management (AWM) is increasingly transitioning towards transformative thinking, where interconnected sectors, including water, energy and food, are managed holistically. Trends point towards cross‐sectoral and harmonised strategies to optimise water use efficiency and productivity, integrate renewable energy, promote ...

Recharge to the chalk aquifer beneath thick till deposits in East Anglia [PDF]

open access: yes, 2004
This report describes the results of a project to investigate the Chalk-till groundwater system in East Anglia and to estimate rates of recharge through thick till (boulder clay) deposits. The project has involved drilling two cored boreholes, monitoring

Isogeochemical Characterization of Mountain System Recharge Processes in the Sierra Nevada, California

open access: yesWater Resources Research
Mountain System Recharge processes are significant natural recharge pathways in many arid and semi‐arid mountainous regions. However, Mountain System Recharge processes are often poorly understood and characterized in hydrologic models. Mountains are the
