Dam | Reservoir Ground Stability
Canelles Dam, built in the 1950s, is located on a subsidiary river of Ebro in the Iberian Peninsula. With a capacity of 108 MW, the dam plays a major role in the south-eastern hydropower system of the river. This 140 m-high by 200 m-long gravity dam has a reservoir capacity of 912.6 hm3 and a total surface area of around 1,800 ha.
Two InSAR studies were carried out focusing on a complex relief and steep slope area covered by rock outcrops, bush and forest:
- a first historical study analysed the ground stability of the water reservoir from 2003 to 2010,
- while a second monitoring programme covered the period from 2015 to 2016.

Our InSAR studies have offered an entire picture of the dam and slopes complementing standard and discreet monitoring point surveys.
