c   XXX this appears to be incorrect.  Will calculate melt runoff if
c       irrigation has occured on a day without rainfall in the middle
c       of the summer.  06-22-94 04:49pm  sjl
c       however there is probably a flag for frozen soil
c       that i do not know about, i added following condition for my work
c
c
c    ...if 5 day avg temp less than freezing count runoff as melt runoff
c    otherwise it will be calculated as irrigation runoff06-27-94 10:49am  sjl
c
c XXX   The following causes problems with the water balance, because
c       melt runoff events on days in which average temp is greater
c       than 0 degrees Centigrade are not added in.  Change this so that
c       it checks melt values (wmelt(iplane)) -     dcf  7/6/94
