Table 1 Catchment areas with different center (blue) nodes and indicator values of (red) node under investigation in the selected catchment areas
Distance between red chosen node and blue center node m | Closeness centrality of the red chosen node | Average distance from all nodes to chosen node | Total number of nodes | Normalized closeness centrality | ||
|---|---|---|---|---|---|---|
C(v) | \(\sum_{n=1}^{N}S\left(v,n\right)/(N-1)\) | N | CN(v) | |||
