Channeling of the arroyo Gómez

Existing Situation

Over the last years, the point of connection between the streams Churre and Gómez has been listed as a problematic point of flood risk , in the publication Plan de Prevención contra Avenidas e Inundaciones en Cauces Urbanos Andaluces (PCAI).

To identify the source of the problem it is necessary to know the interrelationship between the Guadalquivir River and the streams Gómez and Churre. This one flows into the Guadalquivir approximately one kilometre downstream. 

Aim of the Projected Works

The works consist of a section of channelling of Arroyo Gómez, delimited by the 3x3m frame in the p.k. 414/690 under the Madrid-Sevilla AVE line and the stream  Churre. The channelling consists in a vaulted conduction of approximate dimensions 1, 5 x 1, 5 m. 

The channelling of the stream will enhance the channelling of water, as well as the hydraulic capacity of the section and the angle of incidence with the Churre stream. 

Description of the Project

The project of the channelling of the stream Gómez in Lora del Río (Sevilla) has three distinct sections:

  • First Section

    The first part runs from P.K. 0+000 to P.K. 0+288 and this section is composed of a slope of riprap. The breakwater has a flooring of 2 meters wide and 1 meter in thickness. The width of the canal in its upper part is 19 meters. On both sides of the channel are two separate roads of 5 meters in width.
  • Second Section

    The second section of the channelling is form by a cross section as an arch in shape, made of textured concrete. This second part runs from P.K. 0+288 to P.K. 0+800, divided into three different sections.
  • Third Section

    Third part of the channelling runs from P.K. 0+800 to P.K. 0+826. The cross section is a concrete framework of 3 m wide and 2.85 metres tall, with a thickness of 25 cm. This framework passes under the road to Constantine and empties into the Churre stream.
