Methodology for the integrated analysis of hazards associated to flooding: proposal adapted to the spatial planning in Mediterranean regions

The objective of this research is to present a methodological proposal for flood analysis, incorporating associated hazards, to adapt the flood assessment to the particularities of the geographical area of the Spanish Mediterranean coast as a risk region. The aim is to give a territorial approach to the analysis of flooding, following the new requirements introduced by the legislation on natural hazards and floods, directing it directly to territorial management and planning for local and regional scales, and seeking an estimate most reliable of his study in Mediterranean regions. Spanish regulations currently establish the hydrological-hydraulic study as a document that evaluates the risk of flooding in an area. The methodology proposes to incorporate into this study an analysis of the potential generation of contributions to the flow by soil erosion in the basin, as well as by mass movements, thus including both quantitative and qualitative information on the contribution of solid particles to the flood flow. The results, after its application in a pilot basin on the Malaga coast, show a better estimation of the flood plate than the methodological proposal with respect to the conventional methodology
