Damage to agricultural wells The damage to agricultural wells was estimated using the available Sentinel 1 SAR images on January 04, 05, 16, 17, 28, 29, February 09, 10. This is a proxy measure of damage estimated by implementing the so-called coherence change detection (CCD) algorithm. Three image pairs were used — two pre-event sets and one post-event set. The coherence layers were calculated for each pair to assess the changes. This damage proxy map (DPM) detects the changes in the built-up area. The number of damaged agricultural wells was calculated based on their location within a 15-meter radius area around a damaged site. The grid depicts the severity of damage in localised areas; in each tile number of damaged wells was divided by the total number of wells.
