These interactive spreadsheets will help you to further explore some of the hydrological problems and equations discussed in the textbook. Each spreadsheet is related to a specific section in the chapter. Read the section, then open the spreadsheet and change the variable values (in the yellow cells) to affect the outcome(s) (the cells with the blue characters). Some spreadsheets contain additional sheets showing graphs, which will also change depending on the values entered (in the yellow cells).
