The Costa Brava, made up of its beaches and its biodiverse marina, is also subject to climatic change. The floods in this coastal region of Catalonia represent one thing Amenaza Creciente for various events, especially during episodes of intense and temporal sea voyages. Due to the combination of beaches, acantiladies and urbanized areas surrounding the sea, the risk of flooding in this area is a reality that is of concern to authorities and residents. The Agència Catalana de l'Aigua (ACA), which deals with the monitoring and management of waterways, has prepared maps of the prey and the risk of flooding, which are more than 1,800 kilometers away and can reach the areas of greater vulnerability on the Costa Brava Blanes , Lloret de Mar and Castell-Platja d'Aro.

Why is the Costa Brava at risk of flooding?

The geographical and climatic characteristics of the Costa Brava, combined with the urban development in the coastal areas, increase the risk of flooding in different areas. The inviernos suelen traer temporales de March and luvias torrenciales, which affect the local coasts, erosion and the coast and cause problems from drainage in urban areas. The Agència Catalana de l'Aigua (ACA) has noted that climate change has intensified these extreme temperatures and increased the frequency and intensity of time, directly affecting coastal regions.

The INUNCAT civil protection plan contains the action protocols before flood events in Catalonia and identifies the flood zones for intensive stays as a result of floods and destruction on the Costa Brava. The expansion of ocean depths and extreme meteorological events particularly affects urban areas in lower zones or drenaje systems adapted to large volumes of water.

Capitals of the Costa Brava facing floods

• RosesLocated in the Alt-Empordà, Roses is one of the places most affected by the time of the sea and the Torrenciales. The ACA, in planning the Trencada Mountains, has identified critical areas that increase water accumulation in urban areas.
• L'Escala: Even in the Alt-Empordà you must be aware of the presence of canals and water bodies in the sea to avoid flooding. Riells' zones and areas near beaches are vulnerable to hazards, separate from the ACA's Peligrosidad maps.
• Sant Feliu de Guíxols and Palamós: These places in the Baix Empordà are close to their location and the presence of the urban districts that surround the municipalities and affect the lower urban areas and beach areas.
• Platja d'Aro and Tossa de Mar: these poblaciones, debido a su cercanía al mar and desarrollo urbanístico zonas bajas, presentan high riesgo de inundación, specialmente en reas Residential s commerciales. Según the ACA, Platja d'Aro and Tossa de Mar show increased vulnerability, both before temporal and intensive stays.

• Blanes: conocida como la Puerto de la Costa Brava, Blanes suffered from a high flood zone, which in its location had to be on the coast of the Tordera River. Intense Lluvias and the accumulation of water can affect different areas of the municipality, especially its coastal and surrounding zone.

• Lloret de Mar: This is a popular tourist place which also has significant significance. The ACA points out that the areas on the beach and in the Lloret area are particularly vulnerable and subject to flooding during intense episodes of life.

Prevention and adaptation measures

To mitigate the impact of floods, local and regional authorities have implemented prevention strategies. The ACA, in collaboration with the municipalities and the Consorci d'Aigües Costa Brava Girona, has promoted the improvement of the drenaje systems and the regeneration of water for the use of environmental and agricultural operations, contributing to a comprehensive response capacity before extreme events. INUNCAT also has emergency aircraft and meteorological warning systems to protect the city.
