Rio Salado, Argentina

Mapping Historic Flood Exposure with Remote Sensing in the Rio Salado, Argentina

The Rio Salado River Basin generates almost 1/3rd of Argentina's key agriculture including meat and soy. Yet over a decade, floods caused nearly $4.5 billion USD in losses and affected 1.4 million local inhabitants almost every year.

Prior to Cloud to Street, the government agency managing the basin - La Autoridad del Agua (ADA) - lacked the information they needed to: zone farmland out of risk zones, design dykes and flood banks, provide tax relief to farmers affected by floods and identify and protect wetland within the watershed.

Now using the Cloud to Street system, the ADA has flood frequency maps for finding areas likely to flood and a watershed analytics tool to quickly assess which farms experienced damage, how flooding is changing over time and how dykes, green infrastructure, and urbanization need to be managed.

The dashboard analyzes over 10,000 MODIS and Landsat images with locally optimized machine learning and provides a history of floodable areas with specific return times, exposed land uses and population, precipitation hyetographs, and spatial and temporal flood trends in the basin.
