Water Seepage. Water seepage refers to the process of groundwater flowing and infiltrating into estuarine and coastal regions, providing nutrients to these areas. This source of nutrients has become increasingly important due to contamination from human activities, such as municipal and agricultural runoff.
2023年11月1日 · With water scarcity and diminishing water quality more acute than ever, canal seepage is drawing increased attention. The primary concern about canal seepage is reduced flow conveyance efficiency (ratio of the flow delivered by the canal to the flow diverted into the canal) – water meant for equitable and timely irrigation to meet crop demands is diminished because of seepage.
2023年1月1日 · Groundwater flow through fractured rocks plays an important role in many geological hazards and engineering failures, ranging from landslides to damage in foundation structures, and to water inrush in tunnels and underground caverns (Li et al., 2014; Zhou et al, ).
2013年5月29日 · Water seepage of the Lake Nam Co is also evidenced by the relatively lower salinity, compared to other lakes in the vicinity. The salinity values for Lake Nam Co have been reported to be 1.7 gl −1 (Guan et al., 1984), 2.9 gl −1 (Williams, 1991), 2.0 gl −1 and 0.9
2024年7月1日 · Structural seepage problems are triggered around the tunnel when the pore water pressure is greater than the contact stress, leading to a decrease in contact stress and seepage pressure. In this case study, the numerical simulation results show that there is a potential risk of water leakage occurring in the lower part of the tunnel.
2021年5月1日 · If the water level rises, this geological structure could play a negative role and lead to essential leakage. Therefore, before constructing the Changlongshan Hydropower Station reservoir, corresponding anti-seepage treatment should be done.
SY3 was selected for carving and labeled J2-1∼J2-5. Distilled water and sodium sulfate solutions with mass fractions of 0 %, 3 %, 5 %, 7 %, and 9 % were used as osmosis solutions. The seepage pressure was set at 0.5 MPa, and the confining pressure was.
2024年6月1日 · Fig. 21 illustrates the numerical infiltration process of water at different seepage time steps at seepage pressure of 7 MPa. The permeability is recorded every 50,000 steps. From Fig. 21 a, after the 7 MPa seepage pressure is applied, the seepage water gradually migrates from the top side through the flow channel.
2015年1月1日 · Among various effecting factors, water is commonly known as one of the major triggers for landslide failures. In this paper, a coupling model of water-seepage and stability analysis has been developed for analyzing the effect of water on the stability of slopes. A combination of spline curves and genetic algorithm is used to locate the critical ...
2017年4月1日 · In order to control the seepage velocity and concentrated leakage, a master valve is installed on the main water pipe, and three valves are installed on the distributed water pipes respectively. In addition, three flow meters are installed on the distributed water pipes.
