• Positive and Negative value (SEEP/W)

    Dear all, I am curious about the positive and negative values when plotting the evapotranspiration and percolation graphs. Regarding the evapotranspiration graph, does a negative value mean water leaving the soil surface? (Based on the rainfall graph…

  • Reduction of soil suction limit (Psiunsat) leads to slower groundwater flow in unsaturated slope

    I am simulating the process of pipe burst induced groundwater flow in an unsaturated slope (see simplified sketch in Figure 1 below). According to the according to the k-function curve, a lower limit of soil suction will make the soil more permeable at…

  • How to guess seepage line in a slope

    Hi, I have to do seepage analysis in a mine waste dump slope, where I have no data of seepage flow. I have only ground water level data not any other water level data. So, how can draw the seepage line or in PLAXIS 2D there is any way to assume the…

  • Steady state flow analysis through a earthrn embankment in plaxis 2D advanced

    Hello I'm doing a steady state seepage analysis of water seepage in Plaxis 2D advanced edition. Could anyone kindly help me out? Thank you

  • How do I do the seepage analysis of an earthen embankment wall?

    Hi, I'm a beginner in plaxis and I want to analyze the seepage characteristics of an embankment dam made out of soil. I want to analyze both drained and undrained cases. Kindly help me out.

  • Embankment reinforced with car tyre

    Hello How do I create a normal soil embankment that is reinforced with car tires? I'm a beginner in plaxis modeling, kindly help me out.

  • Flow only analysis and fully coupled flow deformation calculation type

    Hi, according to the manual the calculation type Flow only can be only used to perform a groundwater flow analysis in both un/saturated soils and no stresses shall be obtained from such an analysis, while on the other hand the calculation type Plastic…

  • cut off wall- earth dam

    Hi, I am having difficulties modelling the seepage in an earth dam enhanced with a cut off wall using Plaxis 2D. The cut off wall is made of plastic concrete and was introduced later as part of a maintenance procedure in order to prevent any potential…

  • Seepage Analysis (Steady State)-Slurry Trench

    I can perform a steady state seepage analysis by defining a non porous element (plate) on a low permeability soil. But If I define non poros element as a lower permeability soil layer (solid), plaxis does not perform the analysis. How can I solve this…

  • Zero water pressure but Permeable

    [PLAXIS 2D] To set zero water pressure, i apply 'dry' of water condition. However, 'dry' option will make no seepage. I want to apply zero water pressure for a certain soil layer and make the layer permeable to consider seepage as well. What can…

    Application PLAXIS LE Version CONNECT Edition V21 Date created 25 January 2021 Date modified 25 January 2021 Spatial variability is of particular concern in performing seepage modeling because there is often uncertainty…

  • Convergence Issues with semi-permeable interface in dam 2d seepage analysis using PlaxFlow

    Dear all, I'm performing a 2D seepage analysis of a tailings dam using the 'PlaxFlow' module. Our design includes a geomembrane in the upstream face of the dam, we are currently modelling it as as an impervious interface element for. As a part of a…

  • Plaxis2D Max Step

    Hello, I'm currently working with Plaxis2D V20, in particular with the 'PlaxFlow' module, to perform a steady state seepage analysis for a tailings dam, without deformation analysis (Calculation type 'flow only'). The dam has a low permeability clay…

  • How can spatial variability help me? [SOILVISION]

    Spatial variability is of particular concern in performing seepage modeling because there is often uncertainty regarding the ability to measure the hydraulic conductivity (both saturated and unsaturated) of the material at the site. It is possible that…
