From Wikipedia

A presentation style developed by a

Japanese architecture firm in which 20 slides

are shown for 20 seconds each. The formatkeeps presentations concise and fast-

paced

Knowledge is like money: to be of value

it must circulate and in circulating it can

increase in quantity and hopefully in

value.

Inflow

Rain or Surface Water that Finds Direct

Entrance by Way of Downspouts, Sump

Pumps, Manholes, and Catch Basins

Infiltration

Groundwater that Enters through

Defective Pipes, Manholes, or Building

Connections

Hydraulic Model Calibration?

Billing?

Basin Selection Tactical Basin Sizes of 10,000 lf to 40,000 lf

Strategic Basin Sizes of 80,000 lf to 120,000 lf

Data Collector

Calculating & Measuring Flow Flow Meters Dont Measure Flow Flow Meters

Measure Depth and Velocity

Using Depth, We Calculate Area

Using Area and Velocity

We Calculate Flow Q = Flow = A*V

With No Velocity, We Can

Approximate with Manning, But

NO DEPTH, NO DATA

D

V

Depth Varies Exponentially (r2)

Velocity is 1:1

Must have Depth to Calculate Q

Installation

Proper Installation prevents debris buildup and extends

the life of the installation and equipment

duration of any metering period!
