A comparison study of streamflow data from the National Water Model to real-world data from local storm events

The National Water Model is a recently developed hydrologic model that simulates observed and forecast streamflow over the entire continental United States. The model uses an advanced system of inputs to produce three ranges of water models: short-range (18-hour forecast), medium-range (10 day forecast), and long-range (30 day forecast). In this study, short-range streamflow data from the NWM was compared to independent stream gage data gathered from 32 points within the city of Austin. A visual representation of the statistical comparison was prepared in ArcGIS pro.
