Study goals
Estimate the magnitude of the combined hydrodynamic effects – intense rain and high tide – in Vila Velha (ES), through low-cost Information and Communication Technologies (ICTs) and demonstrate that several SDGs can be simultaneously achieved.
Relevance / originality
The hydrodynamic behavior of floods is not well known because there is a lack of monitoring actions/strategies, whether due to technical or financial gaps. With the development, improvement and dissemination of the strategies adopted in this work, such difficulties can be overcome.
Methodology / approach
An environmental monitoring device, using an Arduino board and other electronic components, was built to record the height in the water depth. After calibration, this device was installed in the Ataíde stream, given the location's history of flooding.
Main results
On January 12, 2023, the combination of intense rain and a high tide wave produced a scenario of great vulnerability. The most aggravating factor in the recorded hydrodynamics was the increase in the duration of the flood.
Theoretical / methodological contributions
The research demonstrated that it is possible to innovate environmental monitoring strategies using low-cost ICTs. With just 49 dollars it was possible to understand an important behavior of the analyzed site, generating information capable of supporting other important social protection actions.
Social / management contributions
The DWL-5025 device will contribute to face climate change in urban areas. It is currently being improved, but is already capable of providing data for environmental modeling, hydrodynamic risk management and, in real time, supporting civil defense actions.
