### infiltration problem

Hi I'm working with Hydrus 1D on drip irrigation problem i'm trying to calculate the water balance , in fact the total irrigation and rainfall input are equal to 1342 mm however in the out-put file cumulative infiltration is equal to 1700 mm I do not Understand the difference between them. It should...

### Re: axially symmetric domain

sorry for the confusion No the emitter is not a circular drip line with a radius of 1.5m the emitter is rectanglaire (15cm *10cm) and it is far from the trunc 1.5m I worked with a symmetry domain based on the trunc (because roots are symetric around the trunc ) in the field there is two emiiter at t...

### axially symmetric domain

Hi jirka I'm working with hydrus 2D/3D for water flow and solute transport under subsurface irrigation The geometry of my domain was considered as an axially symmetric domain based on crop roots symmetry distribution around the trunk. so in my case The domain was set as a rectangle (in a radial dire...

### root zone pressure head interpretation

I'm always working with Hydrus 2D/3D to simulate the root water uptake under farmer irrigation (inedequate irrigation monitoring) (date palm as crop) the root water uptake parameters used are : P2H= -5m /P2L =-8m ( deciduous Fruit in hydrus catalogue) In the results I found that the root water uptak...

### water balance

Dear Jirka I'm using Hydrus 2D/3D version 3.02 I'm modelling water flow and solute transport under irrigation . the simulation periode is 271 day , the irrigation is a rotation between a flood irrigation and subsurface irrigation for this end I selected VARflux2 for subsurface irrigation and c2 for ...

### BC. options in Hydrus 2D/3D version 1.10

Dear Jirka I'm working with Hydrus 2D/3D version 1.10 I'm solving water flow problem under surface irrigation (like flood irrigation ) the irrigation is applied two time per week , so during irrigation I have atmosperic BC and variable flux BC at the same time my question : Should I work with variab...

### Re: Solute transport and sub-surface irrigation

thank you for your response it was very helpful and I solved the problem however now I'm facing a new problem I'm using Hydrus 2D/3D to simulate water flow and solute transport problem under irrigation. the irrigation method used in this work is subsurface drip irrigation and surface submersion irri...

### Re: Solute transport and sub-surface irrigation

thank you for your response , yes in my case I have an atmospheric BC in fact the irrigation monitoring was done based on "farmer field scheduling" and they use alternative irrigation ( once they irrigate with traditional method " flood irrigation" and once they use subsurface drip irrigation). So i...

### Solute transport and sub-surface irrigation

Hi I'm working with Hydrus 2D/3D , I want to simulate water flow and solute transport under sub-surface irrigation for data palm trees. my question is about the solute concentration I worked with VarFlux1 for irrigation ( since it is subsurface irrigation) and for solute concentration shoud I put it...
