 These Excel spreadsheets calculate the flow rate over a V-notch weir with a 90 degree notch angle (either fully contracted or partially contracted).  A worksheet is also available for fully contracted flow through a notch angle of 20 to 100 degrees.  Flow calculations are based on input for weir and channel dimensions, the head over the weir, and the notch angle if it is other than 90 degrees. A check on fully contracted flow conditions is included for flow over non-90 degree notches. Calculations are in U.S. units.

 These Excel spreadsheets calculate the flow rate over a V-notch weir with a 90 degree notch angle (either fully contracted or partially contracted).  A worksheet is also available for flow over a fully contracted notch angle between 20 and 100 degrees.  Flow calculations are based on input for weir and channel dimensions, the head over the weir, and the notch angle, if it is other than 90 degrees.  Checks on the "fully contracted" requirements are included.  Calculations are in S.I. units.

 This Excel spreadsheet will calculate flow rate through a Parshall flume based on head measurement(s) for both free flow and submerged flow.  Calculations are in U.S. units.

 This Excel spreadsheet calculates flow rate through a Parshall flume for either free flow or submerged flow, based on head measurement(s).  Calculations are in S.I. units.

 This Excel spreadsheet includes calculation of flow rate for flow over a sharp crested rectangular weir, either a suppressed rectangular weir or a contracted rectangular weir.  Calculations are included for the simpler form of the equations for both the suppressed and contracted weirs as well as the use of the Kinsvater Carter equation for all rectangular, sharp crested weir configurations.  This spreadsheet uses S.I. units.

A Sutro weir, also known as a proportional weir, produces flow over the weir that is proportional to the head over the weir.  This spreadsheet carries out Sutro weir design calculations and calculates flow rate over a sutro weir for a specified sutro weir.  Calculations are in U.S. units.

A Sutro weir, also known as a proportional weir, produces flow over the weir that is proportional to the head over the weir.  This spreadsheet carries out Sutro weir design calculations and calculates flow rate over a sutro weir for a specified sutro weir.  Calculations are in metric units.

This Excel Spreadsheet calculates the flow rate over a broad-crested weir for either free flow or submerged flow for user specified values for weir length, weir height, weir coefficient, upstream depth of flow, and downstream depth of flow for the submerged flow calculation.  Also the minimum required upstream head is calculated for free flow and for submerged flow.  Calculations are in U.S. units
