Temporal and spatial changes in the depth of floodwater and the extent of inundation form an essential part of flood studies. This work estimates the flood extent and depth from LiDAR DEM (light detection and ranging digital elevation model) using data from the Synthetic Aperture Radar (SAR)\u2013Unmanned Aerial Vehicle Synthetic Aperture Radar (UAVSAR) and satellite sensor\u2014Sentinel-1. The flood extent showed a decrease between 29\u201330 August and 5 September 2017. The flood depths estimated using the DEM were compared with the USGS gauge data and showed a correlation (R2) greater than 0.88. The use of Sentinel-1 and UAVSAR resulted in a daily temporal repeat, which helped to document the changes in the flood area and the water depth. These observations are significant for efficient disaster management and to assist relief organizations by providing spatially precise information for the affected areas.<\/jats:p>","DOI":"10.3390\/rs14061450","type":"journal-article","created":{"date-parts":[[2022,3,20]],"date-time":"2022-03-20T21:37:17Z","timestamp":1647812237000},"page":"1450","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Flood Depth Estimation during Hurricane Harvey Using Sentinel-1 and UAVSAR Data"],"prefix":"10.3390","volume":"14","author":[{"given":"Sananda","family":"Kundu","sequence":"first","affiliation":[{"name":"Department of Geography, Manipur University, Imphal 795003, Manipur, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7431-9004","authenticated-orcid":false,"given":"Venkat","family":"Lakshmi","sequence":"additional","affiliation":[{"name":"Department of Engineering Systems and Environment, University of Virginia, Charlottesville, VA 22904, USA"}]},{"given":"Raymond","family":"Torres","sequence":"additional","affiliation":[{"name":"Department of Geography, Manipur University, Imphal 795003, Manipur, India"},{"name":"Department of Earth and Ocean Science, University of South Carolina, Columbia, SC 29208, USA"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,17]]},"reference":[{"key":"ref_1","unstructured":"Munich Re (2020, December 01).
