Knickpoints and knickzones can be semiautomatically extracted from Digital Elevation Models in Geographic Information System software (i.e. ArcGIS). The problem with most of existing methods is that they are frequently subjective and require time-consuming data processing. A solution for these problems is a tool designed for ArcGIS, called Knickzone Extraction Tool (KET) which vastly automates the extraction process.
