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 conditions in two regions in Iraq: silty clayey (Babylon province) and sandy (Dibdibba in Karbala province). The results indicate that, for Babylon province, the groundwater flows from the northwest to southeast with a seepage velocity no more than 0.19 m/d; for the Dibdibba region, the groundwater flows from the west to the east with a seepage velocity not exceeding 0.27 m/d. The effectiveness of the presented tool in depicting the seepage velocity was thus demonstrated. The accuracy of the resultant maps depends on the resolution of the four essential maps (groundwater elevation head, effective porosity, saturated thickness, and transmissivity) and locations of wells that are used to collect the data.

Since every potential failure scenario might result in significant losses in both lives and property, the construction of dams needs extensive research to ensure the safety and feasibility of these large engineering structures. In this article, the Analyses should be performed upon specifically to evaluate seepage, slope stability, and soil liquefaction of significant earthen dam. A numerical technique employing the finite element method (FEM) was used in this article. Finite element software (GEO-STUDIO 2022) was used to carry out both steady-state and transient seepage analyses and pseudo-static ground motion That deals with the present work behavior of the Narasimharaya Sagar (Gorakallu Balancing Reservoir) earthen dam which is in the earthquake prone area of Zone II (as per IS 1893-2002).Geostudio 2022’s SLOPE/W, SEEP/W, and QUAKE/W tools examine the stability characteristics slope, seepage, and earthquake (finite element modelling based software). The model with the reservoir at full capacity is initially examined using SEEP/W to identify the piezometric line, which serves as the foundation for SLOPE/W to determine slope stability. Afterwards, it is exposed to a 0.1 peak ground acceleration earthquake motion using QUAKE/W to know its dynamic stability.

“…Geo-Studio is one the advanced software that has been developed based on the finite element methods to analyze different seepage and slope stability problems. Specifically, SEEP/W model, which is one of the Geo-Studio models, has been an effective tool to determine the flow lines, quantity of seepage, pore water pressure, and hydraulic gradient of flow [11][12][13][14][15].…”

One of the main concerns for engineers, during operation of dams, is uncontrolled seepage though the foundations of dams and hydraulic structures which is mainly resulted from poor geological conditions and lead to undermine erosion or piping that may endanger the safety of dam. In this study, numerical models were utilized to evaluate the excessive seepage problem underneath the spillway of Horan 2 Dam in Iraq as the seepage have led to dissipate storge and malfunction the dam. Two treatment methods were proposed to reduce the quantity of seepage by using a cutoff wall and a clay blanket. The results of the models indicated that the foundation of the spillway was unsafe against piping, as the calculated factor of safety was less than the allowable value. A clay blanket of 6 m long is recommended to sufficiently reduce the quantity of seepage and maintain the factor of safety within the allowable limits. As the cut off wall and clay blanket were used, the quantity of seepage decreased up to 73% and 96%, respectively, and the safety factor increased up to 100% and 110%, respectively. As discussed herein, using a clay blanket is the most cost-effective method comparing to using a cutoff wall.
