Bridges crossing the Biobío river ensure a fast and dependable connection, which contributes to the transport options in the region. With the Biobío region being the second largest contributor to the country's GDP, an unreliable transport network is highly undesirable. However, this is exactly what happened since 2016. Some of the bridges crossing the river collapsed, excessive local pier scour near the foundation and negative effects of morphological dynamics were deemed to be one of the causes. Furthermore, Chile is prone to earthquakes and the resulting tsunamis, which can also damage the structural integrity of the bridge. The Chilean Railroad Agency (EFE) wants to realise a new railroad bridge crossing the Biobío river in Concepción, replacing the existing century old railway bridge. To prevent the failure of the new railway bridge, which can result in unnecessary economic damages, the morphological influence and damages due to scour, earthquakes and tsunamis, must be thoroughly understood and modelled. This process of modelling the current and future situations of the Biobío river is part of this project, using Delft3D-FLOW and NeoWave as modelling agents. With the outcomes the programme of requirements and the preliminary design for the bridge are updated and presented.
