Shear Wave Velocity Profiling & Rock Mass Characterization at Pavagadh Hill Using the Multichannel Analysis of Surface Waves (MASW)
A novel application of the Multichannel Analysis of Surface Waves (MASW) method at Pavagadh Hill, part of the UNESCO World Heritage Site Champaner-Pavagadh Archaeological Park, reveals critical insights into subsurface rock mass conditions and engineering properties. The study demonstrates that MASW can effectively characterize shear-wave velocity (Vs) profiles across varying elevations, providing a non-destructive alternative to traditional borehole-based seismic testing. Key findings include the evaluation of subsurface stiffness, rock mass deformation modulus (Em), Geological Strength Index (GSI), uniaxial compressive strength (UCS), and bearing capacity, which are essential for safe foundation design, slope stability assessment, and infrastructure development. The study also classifies sites based on NEHRP criteria using Vs₃₀ values, offering a robust framework for geotechnical engineering applications in heterogeneous geological settings.
Checklist of Spiders (Arachnida Araneae) from Champaner Pavagadh Archaeological Park, Gujarat
A comprehensive checklist of spiders from Champaner-Pavagadh Archaeological Park, a UNESCO World Heritage Site in Gujarat, India, identifies 189 species across 32 families. The study, conducted between 2016 and 2019, highlights the site's rich arachnid diversity, including 27 new records for the region. Dominant families included Salticidae, Araneidae, Lycosidae, Theridiidae, Oxyopidae, and Thomisidae. Spiders were collected using active searching, pitfall traps, and sweep nets, providing the first holistic documentation of this understudied ecosystem's spider fauna.
