Shown is a portion of the river valley for Mud Creek in Jefferson County, Kansas. DEM (shown in shaded relief) 2 Terrain Processing: Flow Direction Each pixel is colored based on its flow direction. Navigating by flow direction, every pixel has a single exit path out of the image. Flow direction map (gradient direction approximation) 3 Terrain Processing: Stream Delineation The Mud Creek streamline is identified (shown in blue) using an appropriate flow accumulation threshold. “Synthetic Stream Network” 4 Terrain Processing: Floodplain Mapping The 10-m floodplain was computed for Mud Creek using the FLDPLN model. FLDPLN is a static, 2D hydrologic model that requires only DEM data as input. Using simple surface flow properties, FLDPLN identifies the depth-varying floodplain in reference to the input stream network (floodwater source). 10-m Floodplain (DTF Map) 5 Amazon River in Brazil (1700 km). 90-m SRTM South DEM data were used.
