Abstract

The purpose of this code is to identify periods of three-, four-, and 10-year extreme low natural flow at Lee Ferry. The code also identifies when the rolling sum of ten consecutive values sums to less than 75 million acre-feet (maf). These values are pulled out from the traces and ensembles in the HydrologyScenarios.xlsx file (Salehabadi, 2024). The results of this code are used to create scenarios of extreme low inflow to Lake Mead.

Description of Contents
1.HydrologyScenarios.xlsx is the input for all three codes. This workbook comes from Salehabadi et al, 2024).
2. MinimumHydrologyScenarios - Folder contains the Python code (MinimumHydrologyScenarios.py) used to find 3-, 4-, and 10-year minimum flows.
3. Old - Folder with older versions of Python code.
4. MinimumHydrologyScenarios/Results - Subfolder that contains results in Excel files, e.g., 3yearsMinimumHydrologyResults.xlsx.

The README.md file below shows an in-depth description of the contents and reproducibility.
