Mr. Patterson, Your students are really lucky to have you. Thank you for reminding what a thesis should means to me. I will keep that in my mind. I will also have a deeper look at the link you sent. Thank you again. m.

Hi there! I am trying to see the boundaries of my three rivers' watershed. I am having an issue on adjoint catchment processing. I attached a screen view of my map. I've read some of the posts related. I think I succeed on filling the sinks. But if you can tell me how can I test it I would appriciate it. Catchment grid seems OK this time to me. I rebooted my computer several times and emptied Temp folder. These don't solve the problem. I've already spent too much time making this analysis. Any suggestions will be appriciated. Thank you. Merve

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...

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.

Yes yes the dialog box seems so simple. What I see is attached. But sir, if the unit doesn't matter, how the result differs when I put P parameter in inches or in milimeters? And when I check the result and divide total runoff volume by total area, the result - I mean total runoff depth value -doesn't match with the auto-calculated value?

Thank you for your interest sir! Here is the link for the script. The file contains datas also. http://arcscripts.esri.com/details.asp?dbid=13311 And here is the original article by creators of the script: ArcCN-Runoff: an ArcGIS tool for generating curve number and runoff maps Actually this is the point, I couldn't be able to understood what units did they produce runoff in...Rrunoff volume is asked to be calculated in cubicmeters (as I needed). Area data is in squaremeters (may be I was wrong) but precipitation is in inches. To be sure I check the results; I look at the statistics for runoff volume column and area column. Division of total runoff volume value by total area value should give total runoff value (in m. or in mm.) as I know but it doesn't. I would appreciate if you could tell me where I am mistaking.

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.
