Hydrologic modeling just got smarter. Stream network delineation has traditionally relied on arbitrary thresholds, often leading to inconsistent or misleading results across different landscapes. This article introduces two new Arc Hydro tools that bring scientific rigor to the process by incorporating real-world runoff data. Learn how you can now generate stream networks based on actual flow rates, improving the accuracy and consistency of hydrologic analysis across diverse terrains.

The Flood Impact Analysis Solution (FIAS) is a workflow allowing users to visualize high peak flow events and quantify the impacts. The workflow assumes that the user posses predefined flood depth rasters for their area of interest; however, a common question amongst users is how to derive this data. Consider this document as the prequel to FIAS as it will assist users in generating the necessary input depth rasters.
