  • Download USBRWeir.xls, version 1.0 - After a long time of calling this "beta" software, I have taken the beta tag off and made a few minor aesthetic improvements. The most notable is that discharge equations now use the traditional "h" and "Q" variables to represent head and discharge, rather than "x" and "y", which were the Excel defaults for curve-fitting.
