Delay (Return Flow) Table - Monthly (*.urm)

The monthly unit response table file contains coefficients to lag return flows. If the variable interv of the control file is a positive value, then interv values are expected for every pattern. If variable interv of the control file is a -1, then the number of values are specified for each pattern. Note a daily model (control file variable iday = 1) requires a variable number of return values be provided (variable interv must be negative). This file is read by subroutine MDAINP.

Row-data Variable Description
Control Data
1 Format (free)
1-1 idly Delay table ID
1-2 ndly(1) Number of entries in delay table idly
Include only if variable interv of the control file is equal to -1
Delay Data
1-3 dlyrat(j,1) Delay factor for time period j
Include as a percent if variable interv of the control file is positive or equal to -1
Include as a decimal if variable interv of the control file is equal to -100
Include ndly or interv delay entries
Repeat for the number of delay tables used in the diversion station file
