These tools help you model the flow of water across a surface.
Fills sinks in a surface raster to remove small imperfections in the data.
Creates a raster of accumulated flow into each cell.
Calculates the direction of flow from each cell to its downslope neighbor(s) using D8, D-Infinity (DINF) or Multiple Flow Direction (MFD) methods.
Computes, for each cell, the horizontal or vertical component of minimum downslope distance, following the flow path(s), to cell(s) on a stream into which they flow.
Assigns unique values to sections of a raster linear network between intersections.
Determines the contributing area above a set of cells in a raster.
