ArcCN runoff script unit conversion

[MERVEOZEREN]

Hello!

I have a question on unit conversion while using ArcCN runoff script. I am using metric measurements. My area data for landuse and soil maps are in squaremeters. Precipitation data is in mm. In original artical writers use inches for precipitation data but they have squaremeter unit for area data as I understood. Should I enter inches parameter for precipitation value or can I use mm parameter as I wanted to take runoff volume result in cubicmeters?

Any ideas there?

Thanks anyway.

Mr. José Luis hello back!

I also read that the model works in ArcGIS 8.3 and 9.0 but I desperately needed this script so I decided to try to load it inspite of having a 10.3.1. version of ArcGIS. I had no idea about how to do it because I am pretty new to GIS world so I found this video on youtube:

https://www.youtube.com/watch?v=EVPzPGW7qVo,  Add DLL to ArcMap - YouTube https://www.youtube.com/watch?v=EVPzPGW7qVo

Followed the procedure and it worked.

Sorry, I have no knowledge about coding with Phyton...

Actually, I also have a question; does the interface of ArcCN Runoff look the same in your version of ArcGIS? Does Precipitation box have a unit statement as it has in original article? Because as I understand something is wrong with my results.

Best regards.

Hello Mr. MERVE:

Thanks for your prompt response. I have seen the video-tutorial but I am not quite sure if it will work in ArcGIS 9.3.1, I tried something similar and it did not. In any case, I'll try again!

Concerning the question you asked, I was not able to integrate that panel into ArcGIS, in fact that is what I am trying to solve at first instance. As soon as I achieve it, I'll provide you feedback.

Bests,

JL

Hello again!

I finally achieved the integration of the interface into ArcGIS 10.2 but, as you experienced, some words and sentences look incomplete. I suppose this inconvenient is related to the version of the model, I mean that ArcGIS 10 is able to read the .dll file but it does not show all commands correctly. In any case, by analising the original paper and comparing the information with what I can see in the interface I understand that precipitation must be implemented in "inches" as a number, as it has been indicated by the author.

Hope this helps!

Hello Mr. José Luis,

It's been a while, forgive me pls. Yes, you are totally right. I inverted the value into mm later on and the problem's been solved. Anyway, I have to implement slope factor to the original formula, so this script is not useful anymore.

Thank you again for your comment...
