| Sumario: | The DIT rainfall prediction model estimates the Rainfall intensity-duration-return period (i-d-T)relationships from pluviographics maximum series with Log-normal distribution. The DIT model is based onan algebraic estimate of the normal frequency factor. DIT incorporates the duration of the rainfall in ananalytical way, giving conceptual meaning to its parameters and allowing their transposition to pluviometricraingage stations (daily rainfall depths records). The i-d-T logarithmic expression has four parameters: A, B,C, q. This paper analyzes the regional behavior of each parameter of the DIT model in two stages: a)Calibration of the four DIT parameters, on i-d-T matrices generated from empirical i-d-T functions availableat several locations, and b) Spatial interpolation of the parameters in a Geographical Information system(GIS), using different methods. The results consist of maps of isolines for each parameter, showing thespatial evolution in central and northern Argentina. The proposed methodology is acceptable regionalizingthe DIT model parameters. |
