Quick Civil was designed to provide fast results for common civil engineering calculations. The program currently includes open channel flow, weir, orifice and time of concentration calculations. Various Manning’s n tables are also included.All calculations can be performed in English or SI units.Please email me at [email protected] with feedback or bug reports.
