Flood Hazards in Flat Coastal Areas of the Eastern Iberian Peninsula: A Case Study in Oliva (Valencia, Spain)

Enhancing resilience against flooding events is of great importance. Eastern Iberian Peninsula coastal areas are well known for high intensity rainfalls as DANA or “cold drop”. Extreme records in 24 h can exceed the annual average historical series. This phenomenon occurs normally autumn due to convective storms generated by existence cold air upper layers atmosphere combined with warm winds coming from Mediterranean Sea. In many Peninsula, their flat topography, sometimes a marsh nature, and natural (e.g., dune ridges) man-made infrastructures) factors, result devastating potential damage risk urban rural areas. this context, paper presents case study town Oliva (Valencia, Spain) how event flow tends spread accumulate along strip populated area, causing damage. From that point, discusses particular issues flood studies should consider such heavy rainy terms hydrological hydraulic models be conducted serve key tool correct assessment. includes statistical simulation rainfalls, model dependency on return period geometry definition all possible water barriers. An analysis disturbance climatic change effects may introduce future also performed.
