Aplicaciones cartográficas para la valoración de superficies de escorrentía. Riu Girona (Alicante)

Cartographic tools to evaluate surface runoffs. Girona river (Alicante) This article describes the methodology used in the cartography, which is used to evaluate the different surface runoffs in the basin. The geographic focus of this experiment is the Girona river, located in the north of Alacant Province. It was necessary to review research studies on runoff coefficients in order to identify the appropriate methodology for this study. The methodology selected helped us to choose a mathematical formula that was constructive in finding the coefficient. We have worked with different spatial variables integrated into a Geographical Information System, in order to combine slops, lithology, land uses and vegetation. In the methodology followed, the process of photo-interpretation was crucial for adapting to the scale of the project and as an assessment tool of the surface.
