Need help in classifying different types of curvatures in ArcGIS

Hello everyone. I need help regarding the classification of curvatures types. In my recent project, I am working on modelling by using GIS. For that, I need a type of curvature which is Planform, Profile and Standard.

I tried looking for articles and studies which can help me out but I couldn’t find any. Can any of you help me in understanding the steps of curvature classification? You can also suggest an article or so in case you know of some.

Thank you so much in advance.

Dear Hamid, thank you for the link. I tried doing it and classified the curvatures; however, it is not as distinct as it should have been. If you can suggest something else or have any advice, then it will be really appreciated. Thank you so much again.

Dolma, computing the second derivative of the surface can help you in calculating the curvature. Also, the planform curvature basically helps in influencing the convergence and divergence of flow.
