Flood Water Protection in the City of Buenos Aires - Case Study
The Arroyo Mendrano is the second largest channeled stream of water running through Buenos Aires. In case of heavy rainfalls it overflows its banks and causes considerable material damage. When the retention basin which had been especially built to collect large quantities of water during strong precipitation events also overflowed, the government decided to have an alarm-system installed to monitor the water level in the basin.
The „Arroyo Medrano“ is the second largest channelled stream of water which runs directly through Buenos Aires, the largest urban area in Argentina.
In case of heavy rainfalls it overflows its banks, floods roads and often causes considerabel material damage. To prevent furhter flooding, the government had a retention basin built which has a volume of 300.000 m³ and which shall help to regulate the discharge of the Mendrano during strong rainfall.
As it happened that even the retention basin was overflowing during an extreme precipitation event, the government had a system installed to monitor the water level in the basin. This system triggers an alarm as soon as a defined threshold is reached.
