Adaptive Determination of the Flow Accumulation Threshold for Extracting Drainage Networks from DEMs

Adaptive Determination of the Flow Accumulation Threshold for Extracting Drainage Networks from DEMs

Selecting the flow accumulation threshold (FAT) plays a central role in extracting drainage networks from Digital Elevation Models (DEMs). This work presents the MR-AP (Multiple Regression and Adaptive Power) method for choosing suitable FAT when extracting drainage from DEMs. This work employs 36 s...
