Popis: The uncertainty of the input data for infiltration systems (e.g. estimates of stormwater flow, pollution, terrain characteristics) favors the use of simple physically based models, such as the Green-Ampt method. The modification of the method, presented in this paper refers to the introduction of a time-changing ponding depth, which allows for continuous calculation of the position of the wetting front in the system, without changes in the boundary conditions at every time step (an analytical solution). Initial testing shows promising results for the infiltration basin, and future results will include testing of a biofiltration unit.
