Hi Parem,
You get cumulative soil evaporative fluxes in the T_Level.out file (parameter name: sum(Evap)).

Dear Hydrus-1D community I hope my email finds you doing well. Presently, I’m using Hydrus-1D to simulate snowmelt effect on soil water conditions. My soil profile is just 1m thick and I have depth integrated observations for 0-10 cm and 10-30 cm depths below ground surface. My models show that once...

Thanks for the information, Jirka. I'm wondering if there are any updates to Hydrus-1D program (that is freely available to anyone) that includes the items you mentioned in the last message (e.g., NPD=10000). Would you please let me know?

Sincerely,

Hi Jirka,
I hope you are doing well. Would you please let me know if the version 5 of Hydrus-1D is already released?
Sincerely,

Thank you, Jirka.

Thank you, Jirka. I see that there is a column called Volumn in T_Level.out file that provides water volume information for the whole soil profile. I agree with you (thank you for considering my request) that a layer-by-layer water volume information in this file, if included, will be very useful to...

Thank you, Jirka. If you don’t mind, would you please let me know if I may suggest another potential item to include in any new version of Hydrus-1D? If yes, at present the code has option to print out head, vol. water content, flux at node-based observation points (when considering only water flow ...

Hi Jirka, I don't have license to that software. Would you please let me know if I may request for a favor? If yes, would you please let me know if I may request a Hydrus1D executable with NPD set to 2000? I'd really appreciate this favor.
Thanks,
Ravindra

Hi Jirka, Thanks for your reply. I'm still having the same issue. I tried using the GNU fortran 77 compiler (v. 1999), but it gave me several error messages. Some of these messages are listed below. Is there any possibility to request your help with compiling the updated source code (I only changed ...

Dear all, I hope my email finds you well. I have a question. For a project, I need to increase the parameter NPD (number of printing time to 2000 from the default setting of 1000). From the Hydrus 1D source code, I noted I can do this by changing NPD to 2000 on lines 54 in the file HYDRUS.FOR. Howev...

Thank you, Jirka. I noted the issue now. It is not related to input from the snowmelt model, which seems working fine. I found the issue was related to evaporative water loss from the model under snow covered conditions.
Thank you for your help.
Sincerely,

Thank you, Jirka. The reason I didn't include the snow hydrology module with the existing model set up is that I used an external snow model to obtain the daily melt rates and also to account for canopy sublimation processes. I used the resultant daily melt rates from that model as precipitation inp...

Thanks Jirka. I also noted that (through Hydrus-1D simulation) vapor flow has only minor impact on my results. In any case, the increase in theta is related to snowmelt timing at my site.
Sincerely,

Dear all, I’m presently trying to simulate soil moisture dynamics at a location with no vegetation cover using Hydrus-1D. I plan to use this model to understand impact of vegetation on groundwater recharge. The observed data that I have are volumetric soil moisture content (theta) at 10 and 30 cm de...

Thank you for your suggestion, Jirka. After reviewing some of the pre-installed inverse solution examples for 1D case and the Chapter 9 in Hydrus 1D v 4.17 (especially pages 137 and 138), I'm still not sure how to specify sublayer-based averaged moisture content (defined as: volume of water in a lay...
