Formulas for Irrigation Audit

 

 

AC = Average Catch

= (1c + 2c + 3c + 4c + 5c + 6c + 7c + 8c) /. 8

 

ALC = Average Low Catch

= (whichever two collectors are lowest ie 1,2) = (1c + 2c) /. 2

 

 

AD = Average Deviation

= ( ‌|1c AC| + |2c AC| + |3c AC| + |4c AC| + |5c AC| +

|6c AC| + |7c AC| + |8c AC|) /. 8

 

DU = Distribution Uniformity

= ALC /. AC

 

CU = Coefficient of Uniformity

= (1 AD) /. AC

 

SC = Scheduling Coefficient

= AC /. ALC
