So the executable were abbreviated to “SPL” As time passed, utilities were added that were once part of the model. I.e. precipitation and temperature distribution functions were separated from the model and became stand-alone executables (late 1970’s) . The whole system is called WATFLOOD (1990) and its various components have their own names. The hydrological and routing model is now called CHARM (Canadian Hydrological And Routing Model) (2006) .  \nWATFLOOD programs now read only Green Kenue format files. Old file formats are no longer supported. A program called trns.exe can convert old formats to the Green Kenue formats.

WATFLOOD / CHARM User’s Manual | 1-2  \nWATFLOOD/CHARM-with Grouped Response Units  \nWATFLOOD is an integrated set of computer programs to forecast flood flows or do simulations for watersheds having response times ranging from one hour to several weeks. Continuous long term simulation can be carried out by chaining events. The emphasis of the WATFLOOD system is on making optimal use of remotely sensed land cover data, digital elevation models and numerical weather data. These distributed data can thus be directly incorporated in the hydrologic modeling without loss of their inherent detail..  \nCHARM is the first hydrological model to preserve the distributed nature of a watershed's hydrologic and meteorological variability without sacrificing computational efficiency. This has been accomplished through the use of Grouped Response Units, in which process parameters are tied to land cover and land cover mixes can vary from basin cell to basin cell.
