The application of C-band InSAR techniques over densely vegetated areas faces critical limitations due to rapid temporal decorrelation, which requires the deployment of corner reflectors (CR) to ensure stable control points. In this context, traditional site selection criteria are often empirical and tend to overlook the spatiotemporal variability of interferometric coherence. In this study, a multicriteria methodology based on a spatial decision-making framework is proposed to optimize the selection of corner ref...

Mining activities can significantly affect water resources by altering their chemical composition and promoting the mobilization of contaminants in aquatic systems. In this context, this study analyzed the hydrochemical and isotopic characteristics of hydric resources in a mining-impacted region of southern Ecuador in order to identify the main processes controlling water chemistry, determine the origin, and identify potential sources of contamination. Eighteen water samples were collected (10 surface water and 8 ...
