I am working with a large river network polyline shapefile. I am trying to calculate a dendritic connectivity index using a point shapefile representing locations.
The river network shapefile has a large number of rows/individual lines that I merged into one row/line. I want to split this river network into distinct segments where a dam intersects it, where I would be able to calculate the length of each of these segments (fragments). I have tried the "Split Line at Point" tool and this simply split the river network at each vertex, not each point despite it being a single feature.
