Changes in the hydrographic network in a periurban sector of Bahía Blanca due to anthropogenic influence

The lower basin of the Saladillo de García stream, on which the northwestern and western peri-urban area of the city of Bahía Blanca develops, has undergone in recent years a notable intervention resulting from the development of urbanization and related activities. The complex and accelerated proce...

The complex and accelerated process of reconversion in land uses triggers various effects on the hydrographic and geomorphological dynamics of the sector, giving it a new imprint. The urban and industrial expansion mainly produced changes in the configuration of the drainage network in areas prone to flooding and waterlogging mainly to the low values of the land slopes. Therefore, the objective of this work is to identify the changes in the layout of the hydrographic network induced by the anthropic action. In these areas, naturally affected by flooding and waterlogging, a hydrogeomorphological configuration strongly influenced by the diversity in land uses was observed, recognizing different anthropic interventions such as the rectification and channeling of river courses and rectilinear sections adapted to the urban layout. La cuenca baja del arroyo Saladillo de García, sobre la que se desarrolla el periurbano noroeste y oeste de la ciudad de Bahía Blanca, ha experimentado en los últimos años una notoria intervención producto del avance de la urbanización y las actividades vinculadas a ello. El complejo y acelerado proceso de reconversión en los usos del suelo desencadena diversos efectos sobre la dinámica hidrográfica y geomorfológica del sector otorgándole una nueva impronta. La expansión urbana e industrial produjo principalmente modificaciones en la configuración de la red de drenaje en áreas propensas a anegamientos e inundaciones debido principalmente a los bajos valores de las pendientes del terreno. Por ello, el objetivo del presente trabajo es identificar los cambios en el trazado de la red hidrográfica inducidos por la acción del hombre. En estas áreas afectadas naturalmente por anegamientos e inundaciones se observó una configuración hidrogeomorfológica fuertemente influenciada por la diversidad en los usos del suelo reconociéndose distintas intervenciones antrópicas tales como la rectificación y canalización de los cursos fluviales y tramos rectilíneos adaptados al trazado urbano. En mucho de los casos contribuyen al aumento de áreas inundables.
