This study provides experimental evidence of Forchheimer flow and the transition between different flow regimes from the perspective of the pore size of permeable stone. We first carry out seepage experiments on four kinds of permeable stones with mesh sizes of 24, 46, 60 and 80, corresponding to mean particle sizes (50 % by weight) of 0.71, 0.36,...
Article
Heavy metals with high average background values in soils from karst regions of China have been reported previously. However, the accumulation mechanism of heavy metals in karst soils derived from different parent materials related to the molecular soil chemistry is still unclear. In this study, six soil cores (0–100 cm) from three locations were c...

The contaminant transport processes in karst water systems have a direct impact on the quality and utilization of karst water resources. The storage and release of contaminants or conservative solutes during the solute transport process is a common phenomenon in karst aquifers. The impact of the storage and release is more prevalent after focused r...
Article
An Intermittent karst spring is a particular type of groundwater discharge with periodic groundwater flow processes, but a systematic understanding of its hydrological cycle process is lacking. This study considers the Chaoshuidong Spring (CSD), an intermittent karst spring in China, as an example. Integrated water chemistry and isotope methods wer...

Herein, we conducted a study of the Zhangsanxi karst groundwater system in Zhangjiajie, Hunan Province, China, and used the results to develop a method for identifying the aquifer medium and its structural characteristics. To begin, rainfall, underground river flow dynamics, and groundwater level dynamics in the Zhangsanxi karst groundwater system...

This study provides experimental evidence of Forchheimer flow and transition between different flow regimes from the perspective of pore size of permeable stone. We have firstly carried out the seepage experiments of permeable stones with four different mesh sizes, including 24 mesh size, 46 mesh size, 60 mesh size, and 80 mesh size, which correspo...
Article
Well testing in double-porosity fractured aquifers or oil and gas reservoirs is one of the long-lasting research problems in subsurface hydrology and petroleum engineering, where the double-porosity implies that the media of concern can be approximated as a two interrelated continuum (fracture network and rock matrix) with two distinctively differe...
Article
Full-text available
It is a challenge to describe the hydrogeological characteristics of karst aquifers due to the complex structure with extremely high heterogeneity. As the response of karst aquifers to rainfall events, spring discharge variations after precipitation can be used to identify the internal structure of karst systems. In this study, responses of spring...

Terrestrial subsurface acts as a buffer in regulating land surface water and energy processes. In integrated modeling with land surface models, the regulating capacity of the subsurface is largely determined by the bottom boundary condition placement (BBCP). Considering increased human activities nowadays, numerical experiments by integrated hydrol...
Article
This study provides experimental evidence of Forchheimer flow and transition between flow regimes from the perspective of particle uniformity coefficient. We have designed two series of experiments to investigate the particle size control on Forchheimer flow, including two kinds of quartz sands with mixed particle sizes according to different mass...

The arsenic concentration in groundwater varies significantly with time and space in groundwater-surface water exchange zones. Various processes have been identified that control arsenic concentration distribution and mobility in laboratory systems. However, it is still challenging to identify important processes controlling arsenic concentration d...
Article
This work aims to investigate the effects of particle size on flow regimes and validation of Darcy law. Experiments were conducted in sand columns with five different particle sizes of silica sand in mean diameter 1.075 mm, 1.475 mm, 1.85 mm, 2.5 mm and 3.17 mm. Both pre-Darcy flow and post Darcy flow were identified but no obvious linear flow was...
Article
The shared understanding of law on movement of groundwater is that linear Darcy's law is the most basic equation of groundwater seepage. All the mathematical problems of groundwater flow can be derived based on Darcy's law if the the Reynolds number is less than a certain value between 1 and 10 (Re<(1-10)). The experimental data obtained by Darcy a...
Article
Full-text available
One-dimensional uniform flow in homogeneous porous media was experimentally investigated. Head drop experiments were conducted in four test tubes with cubic arrays of spheres in diameter 3 mm, 5 mm, 8 mm and 10 mm. The experimental results indicate that Darcy’s law should be an approximate expression by neglecting the inertial term for flow at low...

It's important to study the relationship between water content and shear strength of unsaturated soils for engineering practice. On the basis of concluding the previous tests results, direct shear tests of undisturbed soil and remolded soils of which the water contents are controlled by two different ways are conducted, choosing the unconsolidated...
