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…

I´d like to know how many m3 water gets through to the other side of a wall during a certain period of time. I have an embankment with a retaining wall and i´m doing a groundwater flow analysis. I have nice results regarding groundwater head, pore pressure…

Hello, I've noticed an unreasonable difference of the maximum value and minimum value of groundwater flow when changing between the shadings and arrows views as presented below (0.7910 vs 0.9002). Is it because one is showing the value for a stress point…

Hi all, In the flow analysis, the cross-section is cut through (2,11) and (5,11) for qy and iy as shown below. This is the homogeneous soil with kx=ky=0.6221 m/day. here q=ki and left side of flow qleft = iyleft * k = 0.2063 * 0.6221 = 0.12834…

Hi all, I modeled a drain with a normal behavior (starting from y=15m to y=12m). I provided the groundwater head of the drain as h=12m. I did the steady state flow analysis and thought the groundwater would be drawdown to h=12m from h=15m. But in the…

Hi all, I need to provide the diameter, length and distance of the weep hole in the retaining wall. For that reason I used flow analysis by providing a retaining wall and drain but water flow around the retaining wall not through the drain, Can anyone…

Hi guys, I have an issue with PlaxFlow (Plaxis 2D). I have a model with a fully coupled flow deformation. It is a time-dependent analysis of deformation and pore water pressures. So soil permeabilities are required. In my current model, I need to…

Hi, I modeled and embedded beam row in plaxis and simulated groundwater drawdown using steady State flow analysis and setting ground water heads at the extreme boundary and excavation level. I noticed that I was getting a little bit of heave behind…

Hi, How can I obtain he x/y coordinates of the calculated phreatic surface (i.e. zero pressure line)? I can view the phreatic surface but don't know how to obtain the x/y coordinates of the zero pressure line. Thank you

Good morning, I'm trying to define the global stability of an embankment supported by a gravity wall. In this case, I would like to perform an analysis in which the water level must be divided into two segments: one behind the wall at a height equal to…

Hi I want to discuss with you two topics, regarding a dewatering with wells of an excavation using 2D Plaxis Steady state Groundwater flow analysis. Left boundary is Closed due to the half-symmetrical modelling. First: How do we determine the necessary…

Hi I am modelling a dewatering of an excavation, using 2D Plaxis V21 in the "steady state ground water flow" analysis. For me it is not clear how I should set the global water level or what kind of influence this water level does have. I made three…

Hi all, When we model the trial trenches in Plaxis (to find the utilities inside the ground, so can't provide embedded depths), how to draw the GWT to get the full water effect? If I used the groundwater flow and the head pore water pressure provided…
