Title
Pennsylvania 3m lidar flow accumulation 2019 [Pennsylvania] {2019}
Description
This dataset represents the upstream flow accumulation, or contributing drainage area, in units of square meters, calculated from the dataset "Pennsylvania 3m lidar digital elevation models 2019", organized by HUC8 watershed. Flow accumulation was calculated using the "carve" approach in TopoToolbox (Schwanghart and Scherler, 2014). Flow accumulation does not account for incoming flow from outside HUC8 regions, and so should be used with caution when interpreting large trunk streams that cross HUC 8 regions. This project was funded by the Pennsylvania Department of Environmental Protection (PADEP) through its Water Program. April 2025. Schwanghart, W., Scherler, D., 2014.
