thank you for the information regarding the previous query i wanted to check the potential infiltration and recharge from a 12m diamter and 40 m deep circular pit with axis symetric domain type. i applied constant head at bottom 40 and equilibrium B.C from lowest located in sides with same 40 m. sim...

hello sir, Glass, J., J. Šimůnek, and C. Stefan, Scaling factors in HYDRUS to simulate a reduction in hydraulic conductivity during infiltration from recharge wells and infiltration basins, Vadose Zone Journal, 19, e20027, 19 p., doi: 10.1002/vzj2.20027, 2020. with reference to above paper i am simu...

sir, thank you for the quick response, 1) input is the same except for the initial conditions. for inverse solution i used my pressure head values say -27.796 and -114.849 (region 1 and region 2 but same material) obtained from converting water content 0.396 and 0.32 using van Genchten relation (for...

hello sir, 1)after optimizing the water flow parameters (theta r, theta s, alpha, n , ks except l) if i use these optimized parameters for forward simulation then model should give same values as fitted pressure for different time but i am getting slightly different pressure values than fitted durin...

sir, i run the model for pressure initial conditions by changing after each run still the same water content change problem. when i run the model for constant water content below well bottom (0.396 in R2) and linear distribution with depth from well bottom to surface (R1= 0.396 to 0.32), i got the e...

hello sir, i run model for inverse simulation for drywell or pit with 2 regions (R1 well bottom to top surface and R2 below well bottom), my initial volumetric water content in R1 is 0.32 and R2 is 0.396 ,i used this water contents for getting pressure head values by Van Genucheten relationship and ...

Sir , i have simulated water loss from well for the axis-symmetric domain but i need to design geometry in a 3D Soil block installed with well. 1) is it possible to design 3d well in soil block and can we apply reserviour BC for this? if yes pls give me steps to design a small well of diameter 100 c...

thank you sir, 1) i used initial parameters from neural network prediction by known sand , silt , clay % values and average bulk density ((well top + well Bottom)/2), , and i want to optimize these values with inverse solution for the falling head, the problem with these initial value is that after ...

sir , note: i am using 3D profesional licensed version 3.xx i am applying seepage face Boundary condition first and then after in reservoir boundary condition window i am applying initial water level in the well and well bottom level (i mean Z coordinates respectively), radius of the well. 1) my que...

sir, sorry for the trouble, initially i practiced the project without considering stone chips (Gravel) filled around the slotted pvc pipe (The project that u sent back after correcting Reservoir BC). after that i run the model for considering the stone chips filled around the pvc pipe (30 cm Diamete...

sir, i run model for inverse solution with two material (1 sand to compensate gravel porosity & sandy clay loam) . after running the model why there is no correlation matrix and why its showing observed cumulative water loss depth only but not fitted cumulative water loss (instead showing depth of w...

sir, thanks a lot for clarifying errors in the boundary condition selection in previous. in the image attached you have given diameter instead of radius of pit i think (Reservoir) and further i run the model with radius of pit 32.5 cm as per my case dimensions. my another question is that, 1) Now i ...

sir, i used hydrus 3d version 3.04 (Licensed version)to simulate infiltration from the small pit having dimensions of 85 cm deep and 65 cm diameter in 2D Domain . initially pit was filled upto 82 cm and water in the pit was noted for different time period. i run the model to optimize the hydraulic p...

dear sir,
herewith i am attaching project file, please find the error that is causing no fitted values in results. i am beginner in hydrus model study i could not able to understand the issue.

dear sir, i am simulating flow through pit using hydrus 2d/3d professional licensed version by inverse method to estimate soil hydrualic properties. with a pit dimensions of 65 cm wide and 85 cm deep, i applied bottom and sides boundary condition for axis symmetric flow as variable head 1 with initi...
