2. What is the most typical way to attenuate storm water runoff today?
Static Control Structure
3. Description/Capabilities:
• Fixed opening;
• Attenuate the peak flow rate;
• Discharge is proportional to depth of water;
• Attenuate single or multiple design storms;
• Discharge by reservoir routing equations.
Limitations:
• Do not control the volume of runoff;
• Naturally delay basin peak time;
• Discharge higher flow rates during the trailing end
of the storm;
• Can contribute to downstream erosion;

5. So what is Flood-Con?
1. Patented automated flood control
device;
2. Composed of a rain gauge, depth
sensor and uses program logic to
emulate (re-create) pre-developed
storm water runoff from a site
development.
6. Description/Capabilities:
• Provides downstream channel protection by replicating the
natural pre-developed flow rate;
• Attenuates actual storm events in real time for any rain event;
• Prevents downstream flooding resulting from delayed peak flow
time;
• Replicates pre-developed developed peak flow time(s);
• Variable orifice openings;
• Follows the pre-developed hydrograph;
• Discharge is independent of depth of water;
