Many geomorphic phenomena such as bank failures, landslide dams, riffle-pool sequences and knickpoints can be modelled spatial point processes. However, the locations of these are constrained to lie on or alongside rivers, their analysis must account for geometry topology river networks. Here, we introduce a new numeric class in TopoToolbox called Point Pattern Stream networks (PPS), which supp...
