Geomorphological analysis and evolution of an altered floodplain drainage system. The case of the Partido Stream (Spain)

The Partido Stream is a small torrential course that flows into the marsh of the Doñana National Park, an area that was declared a World Heritage Site in 1994. Before 1981, floods occurred, and the stream overflowed onto a floodplain. As an old alluvial fan, the floodplain has its singular orography and functionality. Fromthe floodplain, several drainage channels, locally called caño, discharged into themarsh. The Partido Streamhad themorphology of a caño and covered approximately 8 km from the old fan to the marsh. The stream was straightened and channelised in 1981 to cultivate the old fan. This resulted in floods that were concentrated between the banks in the following years, which caused the depth of water and the shear stress to increase, thus, scouring the river bed and river banks. In this case, the eroded materials were carried towards the marsh where a new alluvial fan evolved. Control measures on the old fan were implemented in 2006 to stop the development of the new alluvial fan downstream over the marsh. Thus, the stream would partially recover its original behaviour that it had before channelisation, moving forwards in a new, balanced state. The present study describes the geomorphological evolution that channelisation has caused since 1981 and the later slow process of recovery of the original hydraulic-sedimentation regime since 2006. Additionally, it deepens the understanding of the original hydraulic behaviour of the stream, combining field data and 2D simulations.

House of the Infinite. Vt House, Cádiz 2014

On a marvelous place like a piece of earthly paradise, at Cádiz, we have built an infinite plane facing the infinite sea, the most radical house we have ever made.

Rufo House, Toledo (Spain) 2010

The brief was to build a house on a hilltop outside of the city of Toledo. The hill faces southwest and offers interesting views of the distant horizon, reaching the Gredos Mountains to the northeast = Se trata de levantar una casa en lo alto de una loma, a las afueras de Toledo. La loma está orientada a suroeste y tiene unas vistas muy interesantes de horizonte lejano, al noroeste, que alcanzan hasta las montañas de Gredos.
