Due to decades of aging engineering and ancillary problems, these reservoirs pose great threats to the safety of local people and the development of the surrounding economy. In this study, the surface deformation information for the Banqiao Reservoir is monitored with the small baseline subset\u2013synthetic aperture radar interferometry (SBAS-InSAR) method using 80 Sentinel-1A images acquired from 3 January 2020 to 20 August 2022. Additionally, ground measurements from the BeiDou ground-based deformation monitoring stations were collected to validate the InSAR results. Based on the InSAR results, the spatiotemporal deformation features of the dam were analyzed in detail. The results show that the deformation in most areas, including the dam in the study area, is relatively stable, and the regional deformation velocity of the Banqiao Reservoir dam and other hydraulic engineering facilities varies between \u22121 mm\/y and \u22124 mm\/y. The Ru River area has a relatively obvious subsidence trend, and the maximum subsidence velocity reaches 30 mm\/y. The InSAR monitoring results are consistent with the change trend in the BeiDou ground-based deformation measurement results. The monitoring results for the reservoir dam area provide a reference for local sustainable development and geological disaster prevention.<\/jats:p>","DOI":"10.3390\/rs15123062","type":"journal-article","created":{"date-parts":[[2023,6,12]],"date-time":"2023-06-12T01:59:07Z","timestamp":1686535147000},"page":"3062","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Deformation Monitoring and Analysis of Reservoir Dams Based on SBAS-InSAR Technology\u2014Banqiao Reservoir"],"prefix":"10.3390","volume":"15","author":[{"given":"Zhiguo","family":"Pang","sequence":"first","affiliation":[{"name":"China State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin, China Institute of Water Resources and Hydropower Research, Beijing 100038, China"},{"name":"Research Center of Flood and Drought Disaster Reduction of the Ministry of Water Resources, Beijing 100038, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingguang","family":"Jin","sequence":"additional","affiliation":[{"name":"School of Geography and Information Engineering, China University of Geosciences, 388 Lumo Road, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Fan","sequence":"additional","affiliation":[{"name":"Wuhan Nari Limited Company of State Grid Electric Power Research Institute, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Jiang","sequence":"additional","affiliation":[{"name":"China State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin, China Institute of Water Resources and Hydropower Research, Beijing 100038, China"},{"name":"Research Center of Flood and Drought Disaster Reduction of the Ministry of Water Resources, Beijing 100038, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Lv","sequence":"additional","affiliation":[{"name":"China State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin, China Institute of Water Resources and Hydropower Research, Beijing 100038, China"},{"name":"Research Center of Flood and Drought Disaster Reduction of the Ministry of Water Resources, Beijing 100038, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengjie","family":"Zhang","sequence":"additional","affiliation":[{"name":"China State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin, China Institute of Water Resources and Hydropower Research, Beijing 100038, China"},{"name":"Research Center of Flood and Drought Disaster Reduction of the Ministry of Water Resources, Beijing 100038, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangrui","family":"Cui","sequence":"additional","affiliation":[{"name":"China State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin, China Institute of Water Resources and Hydropower Research, Beijing 100038, China"},{"name":"Research Center of Flood and Drought Disaster Reduction of the Ministry of Water Resources, Beijing 100038, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun","family":"Zhao","sequence":"additional","affiliation":[{"name":"China State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin, China Institute of Water Resources and Hydropower Research, Beijing 100038, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhengjia","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Geography and Information Engineering, China University of Geosciences, 388 Lumo Road, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,12]]},"reference":[{"key":"ref_1","first-page":"221","article-title":"Monitoring dam structural health from space: Insights from novel InSAR techniques and multi-parametric modeling applied to the Pertusillo dam Basilicata, Italy","volume":"52","author":"Milillo","year":"2016","journal-title":"Int.
