Assessing regressive erosion effects: Unveiling riverside land use land cover changes post hydroelectric project construction

Escuela Superior Politecnica del Litoral
Peer-Reviewed Publication

The energy crisis due to climate change is not the only challenge facing Ecuador's dependence on hydropower. On 2 February 2020, the San Rafael waterfall collapsed. Months later, land subsidence and sinkholes were more frequent in the proximity of the Coca River. The authors addressed the problems associated with the operations of the Coca Codo Sinclair hydroelectric

power plant using remote sensing techniques. This is the first study to assess changes in land use and land cover and to analyze fluvial dynamics processes; through a spatio-temporal assessment using satellite imagery.
