description |
The progress of urbanization on the Paranaense rainforest –located in the Central Highlands (Sierra Central) area within the province of Misiones– occurred during these last years has recently started to highlight the need of a comprehensive study on the hydrological response of such anthropized systems. Given that natural conditions of this area (i.e. vegetation cover, soil type, ground elevation) have so far minimized the impacts of flooding, little interest was being put on urban hydrology. Urbanization has changed the natural conditions of surface runoff, increasing the risk of flooding in cities, with the occurrence of higher water levels and faster velocities of flow over the streets. This work focuses on the assessment of the dynamics of surface runoff on the streets within the basin of the Mbotaby stream, in the city of Oberá, Misiones. The identification of maximum water levels and flow velocities on street-ditches within the basin was achieved with the aid of the setting up of a hydrological-hydraulic model, using the SWMM 5.0vE environment onto a number of recurrences. Maps of maximum water levels and flow velocities were developed using rainfall events related to 2, 5 and 100 years of recurrence. Flooding areas over street-ditches were located and quantified for each one of the hydrological events; areas with different flow velocities were identified as well. Finally, threatened areas were detected due to the combination of overflowing water levels and high velocities within the basin. |

A partir del avance de la urbanización sobre la selva Paranaense en la Sierra Central de Misiones, se ha comenzado a evidenciar la necesidad de estudiar la respuesta hidrológica de los sistemas antropizados, en una región que hasta el momento había despertado poco interés en la hidrología urbana, donde las condiciones naturales de cobertura vegetal, tipo de suelo y topografía han minimizado los impactos por inundación. La urbanización ha cambiado las condiciones naturales de escurrimiento superficial, aumentando los riesgos por inundación en las ciudades, con la ocurrencia de tirantes y velocidades cada vez mayores en las calles. Este trabajo se focaliza en la evaluación de la dinámica del escurrimiento superficial en las calles dentro de la cuenca del arroyo Mbotaby, en la ciudad de Oberá, Misiones. Con la constitución de un modelo matemático hidráulico - hidrológico con un alto nivel de detalle, en el entorno de SWMM 5.0vE, se logró la determinación de los niveles y velocidades máximas en las cunetas de calle dentro de la cuenca, para distintas recurrencias. Se elaboraron mapas de niveles máximos y de velocidades máximas para eventos lluviosos de 2, 5 y 100 años de recurrencia. Para los diferentes eventos se localizaron y mensuraron las zonas de desborde de cunetas, como así también se sectorizaron las zonas con distintas velocidades de flujo. Finalmente se detectaron zonas de riesgo por inundación de calles debido a la combinación de niveles de desborde y grandes velocidades CURIHAM: Centro Universitario Rosario de Investigaciones Hidroambientales Facultad de Ciencias Exactas, Ingeniería y Agrimensura.
