WISTOO is an Integral distributed mathematical model used for (1) runoff hydrograph simulation at arbitrary valley cross-section, (2) spatial visualization of hydrological processes and (3) determination of influence of water reservoirs on runoff hydrograph from watershed. It is an Integral distributed model based on hydrodynamic equations describing processes: infiltration,
surface runoff, subsurface runoff and water transformation in river network. Interception and groundwater runoff are described by simplified formulas. Evapotranspiration process is solved
depending on meteorological input data, as Penman-Moteith equation, empirical function or tabular values. The optimal spatial scale varies between 10m x 10m and 25m x 25m for one cell (calculation element) whereas the basic calculation time step is 1 hour. For small watersheds 10 minute time step can be applied
