hydrological models require fine resolution rainfall inputs, enhancing the
practical interest of space-time rainfall models, capable of generating
through numerical simulation realistic space-time rainfall intensity
fields. Among different mathematical approaches, those based on point
processes and built upon a convenient analytical description of the
raincell as the fundamental unit, have shown to be particularly suitable
and well adapted when extreme rainfall events of convective nature are
considered. Starting from previous formulations, some analytical
refinements have been considered, allowing practical generation of
space-time rainfall intensity fields for that type of rainstorm events.
Special attention is placed on the analytical description of the spatial
and temporal evolution of the rainfall intensities produced by the
raincells. After deriving the necessary analytical results, the seven
parameters of the model have been estimated by the method of moments, for
each of the 30 selected rainfall events in the Jucar River Basin (ValenciaSpain)
– period 1991 to 2000, using 5-min aggregated rainfall data series from
an automatic raingauge network. |
