`EF = ( RFH ) / ( A * RFA )`

Enter a value for all fields

The Efficiency of Catchment calculator computes the effectively of a catchment in collecting rain water.

INSTRUCTIONS: Choose units and enter the following:

(A) Catchment Surface Area
(RFA) Rainfall Amount
(RFH) Rainfall Harvest (amount actually captured)

Efficiency of Catchment (EF): The calculator returns the efficiency as a percent and the volume of potential rain captured (harvest potential) in liters.
