| Sumario: | [EN] Nowadays a large number of mathematical models for complex hydraulic flood studies are made, often without the support of a worth full process for the calibration and the validation. Circumstance often justified on the basis of the absence of data, tending to oversizing in order to stay in the best side of safety, but nevertheless with great uncertainty regarding the validity of the results obtained from simulation. Thus the aim of this work is to establish a methodology for hydraulic mathematical modelling calibration, applied to the case of the flood of Valencia in October 14, 1957. Methodology that highlight the relevance of: non-systematic information additions, complementary non-mathematical scientific tools, such the paleohidrology, hydrogeomorphology, or geoarcheoology , and others for support such GIS, remote sensing and photo interpretation, to proceed to the conceptualization of hydraulic behaviour scheme, previously to hydraulic mathematical modeling strictly. These processes of calibration and validation are essential and acquire high significance for the historic character of the special episode, and its transcendence in what it can contribute as recent extreme flash flood for understanding the hydrological and hydraulic processes in the lower Turia River basin. It therefore aims on the one hand try to estimate the order of magnitude of the flood and the phenomena that contributed to its gestation. And moreover determine the error of the fit between the modeling and the fact observed through the traces of the flood taken following the discovery of certain unpublished materials from the flood. On the one hand research conducted allows us to try to establish the order of magnitude of the event, the validation of the then estimated hydrograph, and the phenomena that contributed to its gestation. And moreover allows to determine the error of fit between modelling and fact observed through flood fingerprints extracted from the analysis of large amount of non-systematic information, and in particular of certain unpublished materials of the flood with great value arising in the process of documentary research. These processes of calibration and validation intrinsically linked, are essential and acquire maximum significance for the historical character of the extraordinary episode analysed, and its importance in what it can contribute as a recent extreme flood, for understanding the recent geomorphological, hydrologic and hydraulic processes of the river course at the lower Turia River basin.
