Display Name: Trace Downstream Nov 2024

Description: Using flow accumulation and flow direction grids and a 2km buffer around an input point, create a downstream flow path within the buffered area. Find the distance to the intersected wetlands and nearest impaired water. Find the land use along the downstream path. Uses NLCD 2021 data and NWI scored wetlands processed in 2024 Only for use in WetCAT app. This script is written for ArcPro 2.9
