Storm Water Runoff Analysis Using Python
• Purpose
•
Use Python scripting to derive storm water runoff characteristics, then delineate all
local sub-watersheds and attach the runoff data
• Primary Objectives
•
•
•
Define Sub-watersheds
Quantify Runoff
Host as Web Map (Basic API)
• Spatial / GIS Questions
•
•
•
Where are all of the storm drain inlets in Elma, IA?
How much water drains to each drainage inlet?
What areas have the highest runoff concentrations?

•
First Flush
90% of Storms
WQv = C * P * A
C = Runoff Coefficient
•
•
0.05 + 0.009(x)
X = % imperviousness
• P = Storm Value (1.25”)
• A = Area
• Rational Method
•

•
Urban Setting
Homogenized Areas
Q =C * I *A
C = Runoff Coefficient
I = Intensity (in/hr)
•
Volume (Watershed In.)
• A = Area
