<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

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. The experimental study yields that the heaped-up gravels are stabilized by installing the consecutively assembled boulders on the gravels. Also, small mean

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. Furthermore, the influences of seepage pressure and stress on creep deformation, long-term strength, Poisson’s ratio, and seepage velocity were analyzed. According to the experimental results, the influence of seepage on the creep of soft rock cannot be ignored. The results show that the seepage leads to a decrease in triaxial strength and long-term strength, and an increase
