Webreach (in HSPF), or may be assumed to leave the system (i.e. a diversion out of the watershed). While HSPF can model two or more reservoir outflows separately (e.g. gate and spillway) and still route them to the same downstream reach, WinHSPF currently is capable of displaying a watershed schematic showing only one exit from each reach. WebHSPF is a measure of the efficiency of a system and the units are the same to that of the SEER. HSPF, however, measures the efficiency of the system in heating mode, not in cooling mode.
