Public Release

Tools in this repository were developed by Dewberry in its role as part of STARR II, a FEMA Production and Technical Services provider, to facilitate the automation of hydrologic computations for probabilistic flood risk studies.

Computational approaches were developed in coordination with engineers at COMPASS, and guidance from engineers and scientists at FEMA, USACE, USGS, and NOAA.

PrecipTable (Notebook)

• Download gridded data from NOAA Atlas 14 PFDS:
• User provides a vector polygon for Area of Interest (AOI)
• User provides selected storm durations
• Calculate average values within an AOI for:
• Mean precipitation
• Upper & lower confidence limits

EventsTable (Notebook)

• Execute random event sampling using normal and lognormal distributions
• Randomly pair precipitation totals (volume) with temporal distributions (shape) to create a suite of events
• Performs convolution calculations to group like events based on volume and shape relationships
• Develop probabilities for paired events
• Write intermediate and metadata files to disk

Core - Codebase for operations performed in notebooks.
