Design flow studies for specific return periods are sometimes desired for hydraulic and hydrology researches. This project was focusing on automatic design flow calculations for a given USGS gaging station with code written in Python. The code was created with the help of the Jupyter Notebook with Anaconda 5.1 from Mygeohub. Ev1 distribution was applied for flow calculation. Peak flow data was downloaded from USGS by its URL.

Notes for reproducing this project:

USGS 03335500 was selected as a sample gaging station.

All recorded peak flows from URL were used for design flow calculations.

10, 25, 50, 100, and 500 year return periods were used in this project, more return periods could be applied.
