Hydrology, Hydraulics, Climate and Wetland Resources

Notice – The following spreadsheets, computer programs and supporting documentation are tools to assist with typical hydrologic or hydraulic calculations or wetland hydrologic evaluations.  The engineering practitioner must understand the assumptions and calculations contained in these tools and is responsible for their appropriate use.  Some of the spreadsheets contain macros. 

Many additional engineering spreadsheets are available in the Wisconsin Engineering Spreadsheets section.
