As a beginner, I am very happy to receive your reply. Thank you very much for taking the time to respond to my questions. I don’t know how to get the relevant case code, so I have the following questions: (1) Go through the guidance manual, I can already easily analyze the area I am interested in. I have also tried to use the code area on the Blog archive to analyze, but I did not find out how the flowpathapp and streamproj function output is chi-elevation or distance-elevation (2) How to interactively select the specified river for slope-area fitting to obtain the Ksn value, so I would like to ask where can I find the relevant case code.
Here I wish you a Merry Christmas in advance.
