Analyzing Joshimath’s sinking: causes, consequences, and future prospects with remote sensing techniques

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: May 13, 2024

The Himalayas are highly susceptible to various natural disasters, such as the tectonically induced land deformation, earthquakes, landslides, and extreme climatic events. Recently, Joshimath town witnessed a significantly large subsidence activity. phenomenon resulted in development of cracks roads over 868 civil structures, posing significant risk inhabitants infrastructure area. This study uses time-series synthetic aperture radar (SAR) interferometry-based PSInSAR approach monitor deformation utilizing multi-temporal Sentinel-1 datasets. line sight (LOS) velocity for region, calculated year 2022-2023 using PSInSAR-based approach, varies from - 89.326 + 94.46 mm/year. ve sign indicates LOS velocity/displacement away SAR sensor, whereas signifies earth's movement towards sensor direction LOS. In addition, investigates feature tracking displacement analysis high-resolution Planet result this is consistent with results. also estimated periods 2016-2017, 2018-2019, 2020-2021 separately. Our results show that region experienced highest during 2022-2023. During period, maximum was observed north-western part town. 60.45 mm/year (2022-2023), occurred around Singhdwar, north central moderate high order 10.45 south-west an expansion 84.65 13.13 (2022-2023). Towards south-east, rapid subsidence, 5 analyzes causative factors region. Furthermore, work assesses ground conditions UAV datasets acquired most critically affected areas Singhdhaar, Hotel Mountain View, Malhari Hotel, Manoharbagh. Finally, provides recommendations future prospects policies need be adopted critical Himalayan regions deformation. suggests primarily attributed uncontrolled anthropogenic activities, infrastructural development, along inadequate drainage systems.

Published: July 5, 2024

ABSTRACT The analysis of rainfall variability has significant implications for environmental studies since it influences the agrarian economy regions such as western Himalayas. main objective this research is to identify future precipitation trends in parts Beas River basin using modeled data from three models employed Climate Model Intercomparison Project Phase 6. ACCESS, CanESM, and NorESM were utilized obtain meteorological 2015 2100 (86 years). Data global climate downscaled regional level validated with India Meteorological Department (IMD). Mention that local level. nonparametric test, modified Mann–Kendall, Sen's slope estimator (Q) detect trend magnitude. Furthermore, sub-trends series evaluated utilizing innovative (ITA) approach. Results have shown a increasing timescales, indicating more frequent extreme events under all scenarios. maximum 24.9 12.2 (Sen's slope).This study findings hold policymakers water resource managers.

Streamflow Reconstruction Using Multi-Taxa Tree-Ring Records from Kullu Valley, Himachal Pradesh, Western Himalaya

Quaternary, Journal Year: 2025, Volume and Issue: 8(1), P. 9 - 9

Published: Feb. 8, 2025

To study the long-term hydroclimate variability in Satluj Basin, streamflow data was reconstructed using tree-ring width datasets from multiple taxa available Kullu Valley, western (Indian) Himalaya. Five ring-width chronologies of three conifer tree (Abies pindrow, Cedrus deodara, and Pinus roxburghii) significantly correlate with during southwest monsoon season. Based on this correlation, a 228-year (1787–2014 CE) June–August average chronology. The reconstruction accounts for 34.5% total variance gauge records 1964 to 2011 CE. annual showed above-average high-flow periods 1808–1811, 1823–1827, 1833–1837, 1860–1863, 1876–1881, 1986–1992 CE below-average low-flow 1792–1798, 1817–1820, 1828–1832, 1853–1856, 1867–1870, 1944–1947, 1959–1962 Furthermore, period prominent prolonged discharge low-frequency record is indicated 1788–1807, 1999–2011, 1966–1977, 1939–1949, 1854–1864.
