Risk Assessments of Water Inrush from Coal Seam Floor during Deep Mining Using a Data Fusion Approach Based on Grey System Theory
Published 2020-01-01“…For the safety of coal mining, horizontal directional drilling and grouting techniques have been implemented to detect and plug the fractures and conduits that deliver high-pressure groundwater to coal mine. Taking the grouting engineering performed at Xingdong coal mine at 980 m below sea level as an example, we collected the data of grouting quantity, the loss of drilling fluid, gamma value, water temperature, average water absorption, distance between grouting loss points, water pressure on coal seam floor, and aquifuge thickness at 90 boreholes in the mine to conduct grey relational analysis, first. …”

Preferential flow in soils is key to the development of nebkhas in water limited regions
Published 2025-02-01“…However, water use strategies and infiltration characteristics of nebkhas change with their development stages in regions with low precipitation and deep groundwater, and those changes are not well known. Here, we investigated changes in soil properties and quantified preferential flow characteristics with a dye tracer experiment in nebkhas at different development stages including bare sand dunes (BD), and small (SN) and large nebkha (LN) in different precipitation conditions. …”

Analyzing water uptake of apple trees using isotopic techniques in the Shandong Peninsula, China
Published 2025-02-01“…Notably, the isotopic compositions of the xylem water leaned more towards signatures of soil water, rather than immediate irrigation water or groundwater. Given the irrigation water used to be the dominant water source recharging into soil, the weak contribution of irrigation water to plant would be attributed to the high soil evaporation rates during the growth phase, which strongly alter the isotopic composition of irrigation water in shallow soil layers. …”

Experimental Investigation of the Deformation Characteristics of Tianjin Clays under Coupled Dynamic Stress and Seepage Fields
Published 2019-01-01“…Soft soil ground not only bears the vibration load during operation and construction but also receives seepage effects caused by the bursting of pipelines and variations in groundwater levels. Under the coupling action of dynamic and seepage loads, large settlement can occur in soft soil since the deformation is related to both cyclic stress and seepage. …”

Mechanisms linking river flow regime and riparian hardwood establishment
Published 2025-01-01“…A more complete conceptual model of hardwood establishment considers that seeds need to be deposited where soil is moist long enough to develop roots but far enough from the water's edge to avoid mortality in flow fluctuations; for soil moisture to remain within reach of roots, which could require unusually steady flows, a high capillary fringe, or favorable groundwater gradients; and to avoid mortality due to scour or inundation in winter high flows. …”
