The Rivillas flood of 5–6 November 1997 (Badajoz, Spain) revisited: An approach based on Iber+ modelling

The flash flood registered in November 1997 the city of Badajoz (Spain) basin Rivillas river is analysed by means numerical code Iber+. This event constitutes one most destructive flash-floods an urban area Iberian Peninsula. Starting from precipitation data obtained rain stations, runoff entire was simulated to obtain discharge Badajoz. maps with Iber+ reproduce accurately field during actual event. Likewise, time evolution and water depths are accordance testimonies witnesses. Once capability assessed, several scenarios were considered order analyse main causes In particular, simulations show that catastrophic magnitude mainly due blockage bridges. Different hypothetical analyze role intensity bridge maintenance, concluding similar floods can occur under much lower rainfall but poor maintenance.
