Urban infrastructures have become imperative to human life. Any damage these as a result of detrimental activities would accrue huge economical costs and severe casualties. War in particular is major anthropogenic calamity with immense collateral effects on the social economic fabric nations. Therefore, damaged buildings assessment plays prominent role post-war resettlement reconstruction urban infrastructures. The data-analysis process this essential any post-disaster program can be carried...
This paper presents an analysis of the integration between interferometric and intensity-offset tracking-based SAR remote sensing for landslide hazard mitigation in Italian Alps. Despite advantages Synthetic Aperture Radar Interferometry (InSAR) methods quantifying deformation, some limitations remain. The temporal decorrelation, 1-D Line Of Sight (LOS) observation restriction, high velocity rate multi-directional movement properties make it difficult to monitor accurately complex landslides...
The Copernicus Sentinel-1 mission provides synthetic aperture radar (SAR) acquisitions over large areas with high temporal and spatial resolution. This new generation of satellites providing open-data products has enhanced the capabilities for continuously studying Earth surface changes. Over past two decades, several studies have demonstrated potential differential interferometry (DInSAR) detecting quantifying land deformation. DInSAR limitations challenges are linked to SAR properties...
Phase delay caused by atmospheric effects due to spatial and temporal variations of pressure, temperature, water vapor content is one the major error sources in estimation ground deformation interferometric synthetic aperture radar (InSAR>). Therefore, accuracy measurement highly contingent on robustness correction techniques. These techniques rely either auxiliary data such as numerical weather models (NWMs) or analysis phase itself. The delays mixing turbulent atmosphere stratified lower...
Changes in subsurface water resources might alter the surrounding ground by generating subsidence or uplift, depending on geological and hydrogeological site characteristics. Improved understanding of relationships between surface storage deformation is important for design maintenance hydraulic facilities stability. Here, we construct one longest series Interferometric Synthetic Aperture Radar (InSAR) to date, over twenty-five years, study level changes surroundings Lake Mead, United...
Selenga River Delta (SRD), Russia. How is water occurrence changing in the SRD, and what are hydroclimatic drivers behind these changes? The presence of on surface river deltas governed by land use, geomorphology, flux to from Delta. We trained an accurate image classification Landsat satellite imagery during last 33 years quantify its changes SRD. After comparing our estimations with global-scale datasets, we determined hydrological changes. find mild decreases 51% SRD's area 1987-2002...
<p>Man-made reservoirs and lakes are key elements in the terrestrial water system. The increased concern about impact of anthropogenic interventions on dynamics these resources has given rise to various approaches for representing human-water interactions land surface models. Synthetic aperture radar interferometry (InSAR) become a powerful geodetic tool this purpose, by evidencing changes ground surfaces across time space. In research, Lake Mead associated Hoover Dam studied...

<p>The interest for using Interferometric Synthetic Aperture Radar (InSAR) ground motion detection and monitoring is rapidly increasing, thanks to the Copernicus Senetinel-1 satellites which cover relatively large areas with a 6-days revisit time. Ground of many locations, especially urban around world have been studied Sentienl-1 data rate distribution movements reported. For Sweden, example, Fryksten Nilfouroushan (2019) Gido et al. (2020) active subsidence in Uppsala...
<p>Landslides and floods are the two most important geohazards in Sweden. Due to climate change effects, it is believed that risk of occurring these will increase Sweden causing for example land become more prone landslides. Additionally, due isostatic uplift caused by retreating ice sheet, approximately 10,000 years ago, marine sediments involving clays have exposed above sea level Scandinavia. Infiltration fresh water has (and is) leached salt from pores within leading...
<p>In the recent years, southern Sweden has experienced drought conditions during summer with potential risks of groundwater shortages. One main physical effects depletion is land subsidence, a geohazard that potentially damages urban infrastructure, natural resources and can generate casualties. We here investigate subsidence induced by and/or seasonal variations in Gotland, an agricultural island Baltic Sea experiencing hydrological droughts summer. Taking advantage multiple...
