Resumen de Cálculo hidrometeorológico de caudales de avenida para la subcuenca de El Burguillo (río Alberche, Cuenca del Tajo).

Andrés Díez Herrero, Javier de Pedraza Gilsanz

• A hydrometeorological study of flood discharges has been carried out in the El Burguillo subbasin (Alberche River, Tajo Basin, Central Spain), using the Temez's modification of the rational method arid the Sherman's unit-hydrograph method. The maximum precipitation data of 75 meteorological stations were analyzed through statistical and rainfall-flow models, appling additional technics such as geographical information systems (GIS). The results show us that the curve number (CN) is the most important factor for defining the rainfall-stream model. The SCS methodology to obtain it needs the application of a regional multiplicative factor from the empirical calibrating with results of the statistical analysis of flow discharges.
