RORA: The recession-curve-displacement method for estimating recharge
This web site includes information about the use of the RORA computer program for analyzing a streamflow record. The version at this site will read streamflow data in the format that is available from USGS web sites.
The computer program RORA estimates groundwater recharge using the recession-curve-displacement method. The method is based on the change in total potential groundwater discharge that is caused by each recharge event.
The user's manual does not include complete explanation of the computer program; the program user is referred to the documentation report (first item below). Additional information is provided below.
