A New Algorithm for Calculating the Flow Path Curvature (<em>C</em>) from the Square-Grid Digital Elevation Model (DEM)

This paper proposes a flow-path-network-based (FPN-based) algorithm, constructed from a square-grid digital elevation model (DEM) to improve the simulation of the flow path curvature (<i>C</i>). First, the flow-path network model was utilized to obtain an FPN. Then, a flow-path-network-f...
