[HSPF] Ability to provide multiple SCHEMATIC Blocks for multiple years

[mishranurag]

If a user wants to simulate the effect of land use change in an HSPF model, it can be accomplished by using SPEC-ACTIONS. It might be easier to perform the land use change if a modeler can provide multiple schematic blocks for different years to simulate the land use change. These schematic blocks can reside in different files. In this case, the usual schematic block will contain a date range and the name of the schematic block file to use.

Something like the following.

SCHEMATIC
***Date Range & File Name
START 1996/01/01 00:00 END 1999/12/31 24:00 SCHEMATIC1.SCM
***Date Range & File Name
START 2000/01/01 00:00 END 2004/12/31 24:00 SCHEMATIC2.SCM
END SCHEMATIC
