WhatsApp: +86 18221755073[3] The angle of repose is an empirical friction parameter that is essential in models of numerous phenomena involving granular material, most of them actually at slopes much lower than the angle of repose. The angle of repose is therefore relevant for many geomorphological phenomena which is illustrated with the following examples. [4] 1. Subaerial …
