WebBackground and History • The Manning equation was developed by Robert Manning in the late 19th century. It is interesting to note that Manning had no formal training in fluid mechanics or engineering. His background was in accounting, which caused him to search for the simplest solution that best fit the data. • The Manning equation is an ...
