Irrigation/Fertilization Application Error

[Matthew Lombardo]

Hello everyone,

I am irrigating three HRU's in my model to simulate diverting runoff into a detention pond to these HRU's. Previously, my management schedules only included the irrigation operations and it worked like how I wanted it to. Now, I added in fertilizer with the irrigation to simulate the nitrogen concentration that is present in the runoff, and now there neither irrigation nor fertilization being added to my model. I checked this by looking at the hru_wb_day.csv and hru_nb_day.csv. Can someone help me figure out what is going on? At first I had the year of irrigation for all operations set to 1. This didn't work so I changed the year of operation to 2 for all of the fertilizer operations, but this didn't fix the problem. I added screenshots of one of my management operations and the chemical application I made to apply the fertilizer. In my chemical application, I messed with the parameters and didn't see any change in the results. 

Thank you,

Matt Lombardo

Hello all,

I realized that I did not attach my txtinout folder, so I have included it here. I changed the year of operations all back to 1 for all operations.

Thank you,

Matt

Hello all, 

I did not realize there is a new format for reporting issues, so here it is

SWAT+ Issue Report Template

1. Primary Issue Location

• Component: (e.g., QSWAT+, SWAT+ Editor, SWAT+ Executable, or Model Functionality)
• Area of impact: (Model output, specifically irrigation and fertn in hru_wb_day and hru_nb_day)

2. Software Versions

• SWAT+ Editor 3.2.0 / SWAT+ rev. 61.0.2

3. Project Characteristics

• Watershed Details: (Size, discretization settings/HRU thresholds, and location)
• Modeling Aim: (Denitrification modeling by applying irrigation and fertilizer to simulate diverting runoff from a detention basin to a catchment)

4. Description of Issue

• The Problem: I am simulating diverting runoff from a detention basin to a catchement by irrigating and fertilizing three different HRU's that are next to each other, HRU 662, 663, and 672. I am doing this by simulating what would happen if I applied the runoff all of one day or split between 2, 3, 4, or 5 days. This means I have 15 different management schedules. I am doing this for a 1-yr, 2-yr, 5-yr, and 10-yr storm so each management schedule has an irrigation depth and fertilizer load corresponding to the runoff volume of each storm. I am applying these operations on specific days when those storms occur. At first, I only included the irrigation operations in my management schedules and the model successfully applied the irrigation, but when I added in the fertilizer operations the model did not successfully apply the fertilizer and it no longer applied the irrigation. Can someone help me figure out why the management schedules aren't working?
• Step to Reproduce: There is no actual error in the model, but the irrigation and fertilizer is not being applied. The management scedules can be seen in my txtinout folder. 

5. Supporting Data (Optional)

• Link to TxtInOut folder: The link to the folder is in the previous email.
