New: add a new boundary group. When the user select New, a form will appears as shown in Figure 4. Put a BC ID and click OK button. Then a form of boundary type allows the user to assign to the boundary group. There are eight boundary types (Figure 655), the user just enter the number corresponding to boundary type ( e.g if the boundary type is flow, just enter 1) then click OK button.

Import HSPF Data

The Import HSPF button provides access to the import function for the Hydrologic Simulation Program in Fortran (HSPF) (Bicknell et al., 2001). This is a hydrologic watershed modeling tool that is commonly used to predict flows and some water quality parameters. If this tool is used to predict the flows in a basin/watershed in which the EFDC model is being applied, then these results can be imported as boundary conditions for EFDC.
