JZhang_LCondon_CONUS_Topography_Sep2020

This is a national topographic dataset that can support physically based hydrologic simulations at 1km and 250m spatial resolution over contiguous United States. A R package PriorityFlow (https://github.com/lecondon/PriorityFlow) is used to process the national topographic dataset. The processed dataset has been evaluated nationally using reported drainage areas from the USGS stream gage network and runoff simulations with a physical hydrologic model (ParFlow). The dataset along with all the processing scripts are freely to be downloaded and applied in hydrologic models.
