# Stormwater storage screening
# Scope: Rectangular storm pulse with constant outlet rate; no hydrograph routing.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

inflow = 20 L/s
outflow = 5 L/s
duration = 15 min

storage := max(0 L/s,inflow-outflow)*duration [m^3]

check storage capacity budget: storage <= 15 m^3

scenario alternative: inflow = 16 L/s
