Figure 3.14: The CRWR-PrePro Menu Bar

CRWR-PrePro conducts a raster-based terrain analysis that includes burning-in streams, filling sinks, and calculating the flow direction (using the 8- Direction Point Pour Method as described earlier) and flow accumulation grids.

Following a raster-based terrain analysis (Fill Sinks, Flow Direction, and Flow Accumulation commands), a raster-based sub-basin and reach network analysis creates stream definition grids based on threshold (Stream Definition), stream segmentation grids (Stream Segmentation), an outlet grid (Outlets from Links), and delineated watershed grid (Sub-Watershed Delineation). Finally sub- basins and reach segments are vectorized (Vectorize Streams and Watersheds).
