A balanced hydrograph analysis can be started in two ways, either by right clicking on the Balanced Hydrograph Analysis folder in the study explorer and selecting New, or by going to the Analysis menu and selecting New and then Balanced Hydrograph Analysis. When a new Balanced Hydrograph Analysis is selected, the user is required to first enter a Name for the analysis, enter an optional Description, and select a data set from the available data sets stored in the current study DSS file (see chapter 4 for importing data into the study). The Balanced Hydrograph Analysis editor will not allow further edits by the user until the name is defined and the data set is selected. The list of data that can be selected for a balanced hydrograph analysis will only include those data that have a regular interval, like 15MIN, 1HOUR, or 1DAY (E-Part pathname). This data set could be comprised of daily measurements or those of a shorter duration. Generally speaking, shorter duration datasets (such as 1HOUR or 15MIN) should be used in lieu of daily durations. Once a Name is entered, the DSS File Name and Report File will automatically be filled out. The DSS filename is by default a DSS file with the same name as the analysis. The report file is given the same name as the analysis with the extension ".rpt". The Balanced Hydrograph Analysis Editor is shown in the figure below.
