On September 1st, 2014 Teledyne-ISCO released their 7th edition of the Teledyne ISCO Open Channel Flow Measurement Handbook.

Originally published in 1979, the handbook has been updated multiple times over the years and has become an invaluable resource for those in the field of water / wastewater flow measurement.

Sections included in the Handbook:

Introduction to Open Channel Flow Measurement
Weirs
Flumes
Selecting a Primary Device
The Manning Formula
Area Velocity
Flow Measurement System Installations
Discharge Tables*^†
- V-Notch Weirs
- Rectangular Weirs (with and without End Contractions)
- Cipolletti Weirs
- Parshall Flumes

* Introduced in the 6th edition of the Handbook, the flow tables presented in the 7th edition of the Teledyne ISCO Flow Measurement Handbook erroneous run the tables to zero head. Laboratory investigations have repeatedly shown that are minimum heads below flow is not accurately modeled by the standard discharge equation for the primary device.

† Although convenient, Openchannelflow flow recommends the use of its published discharge tables as they provide not only the standardized flow tables but also the discharge equations, source material, and a graphical representation of the correct point of measurement.
