The objective of this paper is to provide a protocol for developing channelized debris flow (CDF) susceptibility maps that consistently categorize the potential for channelized debris flow into four categories: none-very low, low, moderate, or high. The datasets produced following this protocol include a CDF inventory, as well as future CDF initiation susceptibilities, transport susceptibilities, overall basin susceptibilities, and inundation susceptibilities. The protocol is intended for internal use at Oregon Department of Geology and Mineral Industries (DOGAMI), as well as for use by the larger scientific community. By following this protocol, users can produce standardized maps relatively quickly and consistently. These maps can improve awareness of CDF hazards, which will help communities to design strategies that can better mitigate their landslide risks.

The intended audiences for this paper include those in government, industry, and academia who are interested in producing standardized landslide hazard maps. In addition, others may be interested in understanding how DOGAMI CDF susceptibility maps are made.

Funding for this project was initially provided by the U.S. Geological Survey Landslide Program. Additional funding for this project was provided by FEMA through the Hazard Mitigation Grant Program, routed through Oregon Emergency Management (DR-4258-8-F).
