Code to support the "Freshwater Habitat Potential for Chinook Salmon in the Yukon and Kuskokwim River Basins, Alaska" project dataset. These Python notebooks and scripts process synthetic stream networks and DEMs to create unique reach contributing areas (uRCAs) and uRCA valley bottoms (uRCA VBs). The Python notebooks are designed to be run within ESRI ArcPro software and utilize the 'arcpy' module. The data were processed by region and in sections based on National Hydrography Dataset (NHD) Level 8 hydrologic units (HUC8) to reduce the computing workload, and therefore the scripts make use of a naming convention based on HUC8 codes within each regional geodatabase. See metadata records for individual data elements for a description of input sources, software environments, data quality, processing steps, and attribute information. ...
