<strong>Abstract:</strong> The present study investigates the effects of side, vertical, and a combination of both side and vertical suction seepage on the flow patterns in a laboratory flume. To examine streamwise, transverse, and vertical components, an Acoustic Doppler Velocimeter (ADV) is used to analyze the complete velocity readings. The results demonstrate that near-bed velocity is relatively higher under suction seepage conditions than in other conditions. The impact of side suction seepage is primarily in the lower area next to the side wall. The vertical and transverse components of

Abstract:

Seepage velocity is a very important criterion in infrastructure construction. The planning of numerous large infrastructure projects requires the mapping of seepage velocity at a large scale. To date, however, no reliable approach exists to determine seepage velocity at such a scale. This paper presents a tool within ArcMap/Geographic Information System (GIS) software that can be used to map the seepage velocity at a large scale. The resultant maps include both direction and magnitude mapping of the seepage velocity. To verify the GIS tool, this study considered two types of aquifer condition

Abstract:

Unlike conventional single-phase seepage monitoring methods, monitoring multiphase flow in porous media is more complex. This paper addresses this complexity by analyzing the heat transfer in porous media models under multiphase seepage conditions. It introduces a set of theories, methods, and devices to effectively monitor the flow velocity in multiphase seepage processes. Utilizing a self-developed single-point self-heating temperature-sensing device combined with saturation testing at monitoring points, we establish a method to determine the relationship between different saturation and res

There is little information on velocity field of seepage flows. The formation of seepage flow is significant for aquatic habitat including spawning of aquatic animals in river. To create spawning fields in river, the stability of a heaped-up gravels during floods is required for its artificial formation. The velocity measurement of seepage flows is also necessary. This paper presents velocity fields of seepage flows in a heaped-up gravels.

In order to study the creep characteristics and mechanism of red-bed soft rock under the water–rock interaction, fluid–structure coupling triaxial compression tests and creep tests under stepwise loading were carried out.

According to the experimental results, the influence of seepage on the creep of soft rock cannot be ignored.

Abstract:

The seepage underground is rather complicated in the low permeability reservoir and the heavy oil reservoir. One important point to note is that the seepage in these reservoirs does not follow Darcy's law, which brings difficulty to the development of oil field. Study on low velocity non-Darcy percolation theory, the impact on oil production index is analyzed. The key is the summary of the application in order to provide theoretical references for the rational exploitation of the relevant oil fields.

Abstract:

Microbial-induced carbonate precipitation (MICP) is an eco-friendly soil stabilization technique. This study explores the synergistic effects of incorporating hydroxypropyl methylcellulose (HPMC) into the MICP process to enhance the disintegration and seepage resistance of loess. A series of disintegration, seepage, scanning electron microscopy (SEM), and mercury intrusion porosimetry (MIP) tests were conducted. The results show that HPMC forms protective membranes around calcium carbonate crystals produced by MICP and soil aggregates, which enhance cementation, reduce soluble salt dissolution

In this paper, the slurry seepage dynamics model is established, the critical conditions for instability of the seepage dynamics model are discussed, and the effects of power index, effective mobility and non-Darcian flow factors on the seepage velocity are analyzed. The results show that in the two-dimensional logarithmic parameter space, the boundary between the stability zone and the instability zone of seepage is a straight line, and the absolute value of the slope of the straight line decreases with the increase of the power index.

Abstract:

The present study focuses on multi-scale statistical characterization of scour depth at tandem piers and migrating dune-like bedforms forming behind the piers in downward seepage affected alluvial channel, using an experimental approach. Experiments were conducted using two circular piers arranged in a tandem manner for no seepage, 10% seepage, and 15% seepage condition. The erosive capacity of reversal flow is hindered with downward seepage, which results in reducing velocity and Reynolds stress near the bed at upstream of piers in case of seepage runs.

A split grouting-reinforced body (SGRB) is the new surrounding rock that forms after split grouting reinforcement in tunnels and underground engineering, and its shear-seepage behavior is one of the critical factors affecting tunnel stability. The effects of seepage pressure, confining pressure, and the roughness of the soil–slurry interface on the shear-seepage characteristics of SGRB specimens were investigated using a modified triaxial shear-seepage coupling test system. The failure mechanism for the SGRB was analyzed taking into account its seepage behavior and mechanical characteristics.

To study the lateral seepage field in the tension saturated zone (TSZ), an experiment with no evaporation and precipitation infiltration was carried out in a self-made seepage tank filled up with fine sand. Based on the data and plots obtained, the lateral seepage field distribution features in the TSZ can be divided into three area for discussion: ascending area, descending area, and the nearly horizontal flow area. In the ascending and descending area, the total water potential gradient diminished from the recharge area to the discharge area and the seepage velocity was faster. In the nearly
